1.13 – Portfolio Analysis Excel: What Most Investor Spreadsheets Miss
Your Spreadsheet May Track Your Portfolio Without Actually Analysing It
Most investors who use Excel to manage their investments already have a substantial amount of portfolio data.
They know what they own.
They know how much each investment is worth.
They may track purchase prices, gains and losses, dividends, asset allocation and even investment performance.
Some have spent years developing increasingly sophisticated spreadsheets.
Yet there is an important distinction between recording portfolio information and analysing a portfolio.
A spreadsheet can contain hundreds of rows, dozens of formulas and years of investment history while still failing to answer some surprisingly fundamental questions:
What is actually driving my portfolio performance?
Where is my portfolio becoming concentrated?
How far has my allocation moved from the strategy I intended?
Are several investments creating the same underlying exposure?
What does my portfolio look like when every investment account is combined?
Which holdings are contributing meaningfully—and which are simply occupying capital?
What should the information in my spreadsheet cause me to do differently?
These are not tracking questions.
They are portfolio analysis questions.
And that distinction matters.
A portfolio tracker tells you what has happened.
Portfolio analysis helps you understand why it happened, what it means and whether anything should change.
That is the point at which Excel becomes much more than an investment record. It becomes part of a structured investment process. Many investor spreadsheets never make that transition. They become excellent at storing information but relatively weak at turning that information into insight.
The problem is rarely a lack of data.
It is usually that the data remains fragmented.
Performance sits in one worksheet.
Holdings sit somewhere else.
Allocation is reviewed separately.
ETF exposure may not be analysed at all.
Different investment accounts may each appear perfectly sensible when viewed independently.
Nothing brings those pieces together to answer the bigger question:
“What is my portfolio actually telling me?”
This is where the Investor Progression Model becomes useful. Early-stage investors naturally focus on recording investments and monitoring portfolio value.
As their process develops, they begin measuring performance, allocation and other portfolio metrics. More structured investors go further.
They connect those measurements.
They examine relationships between holdings, performance, allocation, diversification, exposure and investor behaviour rather than treating each metric as an isolated number.
A Structured Compounder therefore doesn’t simply maintain a better spreadsheet. They use their spreadsheet differently. The objective shifts from:
“Can I see everything in my portfolio?”
to:
“Can I understand what everything in my portfolio means?”
That is the difference between portfolio tracking and portfolio analysis.
In this guide, you’ll learn how to use Excel to analyse your investment portfolio more systematically, which dimensions most investor spreadsheets overlook and how to turn portfolio data into information that supports better long-term investment decisions.
Discover What Your Portfolio Data Is Really Telling You
Your spreadsheet may already track everything you own.
But tracking more information doesn’t automatically create better investment decisions.

Who This Guide Is For
This guide is designed for investors who already use Excel or another spreadsheet to track their investments but want to extract more meaningful insight from the information they collect. It is particularly valuable for investors who:
already maintain an investment portfolio spreadsheet
track holdings, values, transactions or investment performance
manage investments across multiple accounts
want to understand portfolio allocation and concentration more clearly
own both individual shares and ETFs
have accumulated years of investment data but are unsure which metrics actually matter
want their spreadsheet to support investment decisions rather than simply document them
are moving towards a more structured long-term investment process
You do not need an exceptionally complicated spreadsheet. In fact, complexity is not the objective.
A relatively simple Excel workbook that connects the right information can provide far more useful analysis than an elaborate spreadsheet containing dozens of disconnected metrics. The important question is not:
“How sophisticated is my spreadsheet?”
It is:
“What can my spreadsheet tell me about the portfolio I have actually built?”
If you can see your investments clearly but still struggle to explain your portfolio’s performance, allocation, concentration or underlying exposures, this guide is designed to help you make that transition.

Final Thought
What Is Portfolio Analysis in Excel?
Portfolio analysis in Excel is the process of using your investment data to understand how your portfolio is actually behaving, rather than simply recording what you own. A basic spreadsheet might show:
Investment name
Number of shares
Purchase price
Current value
Gain or loss
Dividend income
Portfolio analysis goes further. It connects those individual data points to answer broader questions about performance, allocation, diversification, concentration and portfolio structure. For example:
Is your portfolio outperforming the benchmark you selected?
Has strong performance in one sector quietly changed your asset allocation?
Are several ETFs exposing you to the same underlying companies?
Are apparently small positions becoming significant when holdings across multiple accounts are combined?
These questions require more than a list of investments. They require the spreadsheet to analyse how the different parts of your portfolio interact.
That is where Excel becomes particularly powerful.
Because the structure is controlled by the investor, information from different accounts, holdings and investment types can be consolidated into one connected portfolio view.
The objective isn’t to create the most complicated spreadsheet possible. It is to create enough structure to understand the portfolio you actually own.
Portfolio Tracking vs Portfolio Analysis
Portfolio tracking and portfolio analysis are closely related, but they perform different jobs.
Portfolio tracking records what happened.
It tells you:
what you bought
what you sold
what you currently own
how much each investment is worth
how much income you received
how your portfolio value has changed
Those are essential foundations. But they don’t necessarily explain what the information means.
Portfolio analysis interprets what happened.
Instead of simply observing that your portfolio increased by 12%, analysis asks:
Why did it increase?
Was the increase caused by investment returns, new contributions or both?
Instead of simply recording that an ETF represents 15% of your portfolio, analysis asks:
What underlying exposure does that ETF create?
Instead of showing five investment accounts separately, analysis asks:
The distinction is important.
Portfolio Tracking | Portfolio Analysis |
Records holdings | Examines concentration |
Records transactions | Explains portfolio changes |
Shows current value | Separates growth from contributions |
Calculates returns | Evaluates performance |
Shows account balances | Consolidates the total portfolio |
Records ETFs | |
Shows allocation |
A Structured Compounder needs both. Tracking provides the data.
Analysis turns that data into information that can influence decisions.
What Most Investor Spreadsheets Actually Measure
Most investor spreadsheets begin for a practical reason. The investor wants somewhere to record their investments. As the portfolio develops, more information is gradually added. A typical spreadsheet may eventually contain:
Holdings
Purchase prices
Current prices
Portfolio values
Gains and losses
Annual returns
Account balances
Some spreadsheets become extremely sophisticated.
They may contain dashboards, charts, automated prices and years of transaction history. But the majority of these measurements still answer variations of three relatively simple questions:
What do I own?
What is it worth?
How has its value changed?
All three are useful.
None provides a complete analysis of the portfolio.
This is why spreadsheet sophistication can sometimes be misleading. An investor may have significantly improved the quantity of information being tracked without improving the quality of the decisions that information supports.
The next stage is therefore not necessarily adding more data. It is learning how to connect and interpret the data already being collected.
What Most Investor Spreadsheets Miss
The biggest weakness in many portfolio spreadsheets isn’t an incorrect formula or a missing column. It is context.
Individual measurements are often viewed independently.
Performance is calculated without considering contributions.
ETFs are recorded without analysing their underlying holdings.
Accounts are tracked separately without consolidating the portfolio.
Individual holdings are monitored without measuring their combined sector or geographic exposure.
The spreadsheet therefore contains the information—but doesn’t always reveal the relationships between it. Consider an investor whose spreadsheet shows:
Portfolio return: +11.8%
That number alone says relatively little. Useful analysis might ask:
How does that compare with the investor’s benchmark?
How much portfolio growth came from contributions?
Which holdings generated most of the return?
Did that performance materially change asset allocation?
Has the portfolio become more concentrated as a result?
Was the return consistent with the amount of risk being taken?
The same principle applies throughout portfolio management.
A number becomes considerably more useful when it is connected to another number, a target, a benchmark or an investment objective.
That is what many investor spreadsheets miss.
Not more data.
More interpretation of the data they already contain.
The Investor Progression Model: From Recording Data to Analysing Decisions
The difference between tracking and analysis also reflects how investors progress.
Within the Investor Progression Model, early-stage investors typically focus on visibility.
They want to know: What do I own and how much is it worth?
As their investment process develops, measurement becomes more sophisticated. They begin calculating returns, monitoring dividends, tracking allocation and comparing portfolio performance over time. But another transition eventually becomes necessary.
The investor must move from measuring individual outputs to interpreting the portfolio as a system.
The progression looks something like this:
An investor might first record portfolio value.
Then measure performance.
Then analyse why performance differed.
Finally, they decide whether anything within the portfolio actually requires attention.
The same progression can be applied to allocation, diversification, ETF exposure and multiple investment accounts.
This is why becoming a Structured Compounder isn’t simply about tracking more metrics.
It is about developing a repeatable process for turning those metrics into better investment decisions.
Move From Measuring Your Portfolio to Understanding It
As investors progress through the Investor Progression Model, the challenge changes. It is no longer simply:
“Am I tracking the right information?”
It becomes:
“Am I using that information to make better investment decisions?”

The Core Dimensions of Portfolio Analysis
Effective portfolio analysis doesn’t depend on one perfect metric. It requires several different perspectives on the same portfolio. At a minimum, a structured analysis should consider:
Portfolio Performance – How the investments themselves have performed over different periods.
Contributions and Withdrawals – How much portfolio growth came from additional capital rather than investment returns.
Asset Allocation – How capital is distributed between equities, bonds, cash and other asset classes relative to your intended allocation.
Holding Concentration – Whether individual investments have become disproportionately important to overall portfolio outcomes.
Sector Exposure – How much of the portfolio depends on particular industries.
Geographic Exposure – Where the portfolio’s economic exposure is concentrated.
ETF Exposure and Overlap – Which underlying companies, sectors and markets are being owned indirectly through multiple funds.
Multiple Account Exposure – What the portfolio looks like when investments held across different accounts are consolidated.
Portfolio Drift – How market movements, contributions and investment decisions have moved the portfolio away from its intended structure.
None of these dimensions should be considered entirely independently. A strong-performing holding can create concentration.
Concentration can change allocation.
ETF overlap can increase sector exposure.
Different accounts can hide both.
The purpose of portfolio analysis is therefore to connect these dimensions into one coherent view of the portfolio.
Analysing Portfolio Performance Properly
Portfolio performance is one of the most commonly measured—and most easily misunderstood—parts of investment analysis.
An investor might begin the year with $100,000 and finish with $125,000.
At first glance, the portfolio appears to have grown by 25%.
But if the investor contributed another $15,000 during the year, the investments themselves clearly did not generate the entire increase.
This is why portfolio growth and investment performance must be separated. A useful performance analysis should distinguish between:
Beginning portfolio value
New contributions
Withdrawals
Dividend and income distributions
Capital appreciation
Total investment return
Portfolio growth
Relevant benchmark performance
Different calculations can then answer different questions.
Simple return can help measure straightforward changes in value.
CAGR can show the annualised rate at which an investment has compounded across several years.
XIRR can account for the timing of irregular cash flows.
Benchmark comparison can provide context for the resulting performance.
No single calculation answers every question.
The objective is therefore not to find the “best” portfolio return formula.
It is to understand which calculation answers the question you are trying to analyse. That distinction turns performance measurement from another spreadsheet output into something that can actually inform your investment process.
Separating Investment Returns From Contributions
One of the most important distinctions in portfolio analysis is also one of the simplest:
A larger portfolio doesn’t necessarily mean a better-performing portfolio.
Imagine an investor starts with a $200,000 portfolio.
During the year they contribute another $30,000.
By year-end, the portfolio is worth $245,000.
Portfolio value has increased by: $45,000
But the investments did not generate $45,000 of return.
$30,000 came from the investor.
Only the remaining change reflects investment performance, before accounting for the timing of those contributions and any withdrawals or income treatment.
This distinction becomes increasingly important for investors making regular monthly contributions.
A chart showing portfolio value steadily rising can create the impression of strong investment performance when a substantial proportion of that growth is simply new capital entering the portfolio.
A structured spreadsheet should therefore allow the investor to see two different things:
Portfolio GrowthHow much larger has my portfolio become?
Investment PerformanceHow effectively has the capital already invested performed?
Both matter.
But they answer completely different questions.
Structured Compounders understand that distinction because they aren’t simply trying to make the portfolio number become larger.
They want to understand what is causing it to become larger.
And that is exactly the type of question portfolio analysis should be designed to answer.
Analysing Asset Allocation and Portfolio Drift
Asset allocation tells you how your capital is distributed across the portfolio.
Portfolio analysis asks a second question:
“Is that still the allocation I intended to own?”
Suppose your target allocation is:
Asset Class | Target | Actual | Variance |
US Equities | 40% | 47% | +7% |
International Equities | 30% | 27% | -3% |
Bonds | 20% | 18% | -2% |
Cash | 10% | 8% | -2% |
The actual percentages provide useful information.
The variance provides context.
It shows where the portfolio has moved away from its intended structure.
This is portfolio drift.
Drift can develop through:
different investment returns
regular contributions
withdrawals
dividend reinvestment
new purchases
deliberate portfolio changes
The objective isn’t to eliminate every variance.
A 2% difference doesn’t automatically require a trade, just as a 7% difference doesn’t automatically mean an investment should be sold.
Analysis should establish why the difference exists and whether it matters.
That creates a more useful sequence:
Target → Actual → Variance → Cause → Decision
Portfolio allocation therefore becomes more than a pie chart showing where you are today.
It becomes a way of understanding how the portfolio has evolved and whether that evolution remains consistent with your investment strategy.
Measuring Concentration Across Holdings, Sectors and Geographies
Concentration is easy to recognise when one investment represents 30% of a portfolio.
It becomes harder when the concentration is distributed across several apparently different investments.
That is why portfolio analysis should examine concentration at several levels.
Holding Concentration
Start by calculating each investment as a percentage of total portfolio value.
This identifies individual positions that have become unusually influential.
But holding concentration is only the first layer.
Sector Concentration
Several different shares and ETFs may collectively create substantial exposure to one sector.
A portfolio containing ten investments might therefore appear diversified at holding level while remaining heavily dependent on technology, financials, healthcare or another part of the economy.
Geographic Concentration
The same principle applies geographically.
An investor may own global funds alongside individual US shares and assume the portfolio is internationally diversified.
But if those global funds themselves contain substantial US exposure, the portfolio’s true geographic concentration may be considerably greater than the fund names suggest. A structured spreadsheet therefore moves through:
Holding → Sector → Geography → Portfolio
Each view reveals something different. The important question isn’t simply:
“How many investments do I own?”
It is:
“How much of my portfolio depends on the same companies, sectors and markets?”
That is a much more useful measure of diversification.
Identifying Hidden ETF Exposure and Overlap
ETFs can make portfolio analysis more difficult because one line in your spreadsheet can represent hundreds or even thousands of underlying investments. Imagine an investor owns:
a global equity ETF
an S&P 500 ETF
a technology ETF
several individual US technology shares
At spreadsheet level, these appear to be separate holdings.
At underlying company level, some of the same businesses may appear repeatedly. This creates ETF overlap.
The issue isn’t necessarily that overlap exists.
Some overlap may be completely intentional.
The analytical problem is not knowing that it exists.
For important ETFs, portfolio analysis can therefore include:
underlying company exposure
sector exposure
geographic exposure
percentage overlap with other funds
duplicated exposure to individually owned shares
This allows the investor to move beyond:
“I own four different funds.”
towards:
“What do those four funds collectively cause me to own?”
That distinction is particularly important as portfolios become more complex.
The ETF name tells you what product you purchased.
Underlying exposure tells you what investment risk you actually added to the portfolio.
Analysing Multiple Investment Accounts as One Portfolio
Investment accounts are administrative structures. Your portfolio is an investment structure. Those two things should not be confused. An investor might hold:
retirement investments
a taxable brokerage account
an employer investment plan
an older investment account
a separate account used for ETFs
Each account may be well diversified when viewed independently. But portfolio analysis needs to combine them. Once consolidated, the investor may discover:
the same investments held in several accounts
duplicated ETF exposure
greater sector concentration than expected
geographic imbalance
asset allocation that differs substantially from the apparent allocation within individual accounts
This is why analysing accounts separately can create a portfolio blind spot.
A structured Excel system should therefore allow holdings from every relevant account to feed into one consolidated portfolio view.
You can still retain account-level information. But analysis should also occur at portfolio level. That changes the question from:
“Is each account properly structured?”
to:
“What structure do all of my accounts collectively create?”
For portfolio analysis, that is the more important question.
Connecting Performance, Allocation and Exposure
The real value of portfolio analysis appears when different measurements stop being treated independently.
Consider an investor whose technology holdings have produced exceptional returns.
Performance analysis shows that technology contributed strongly to portfolio growth.
Allocation analysis shows that technology has increased from 18% to 29% of the portfolio.
ETF analysis reveals additional technology exposure inside two broad-market funds.
Concentration analysis shows that several of the same companies appear across those investments.
Individually, each measurement tells you something useful. Connected together, they tell you much more:
strong performance has materially changed the structure and concentration of the portfolio.
That does not automatically mean anything should be sold.
But it creates a decision that wasn’t visible from the performance number alone. This is the fundamental advantage of connected portfolio analysis.
Performance tells you what happened.
Allocation tells you what changed.
Exposure tells you what the portfolio now depends upon.
Together, they provide context for deciding what happens next. A Structured Compounder therefore doesn’t analyse portfolio metrics as isolated outputs.
They look for the relationships between them.
Why More Portfolio Metrics Don’t Necessarily Mean Better Analysis
It is easy to assume that a better investment spreadsheet needs more metrics. That can become a trap. An investor might track:
daily portfolio movements
weekly returns
monthly returns
annual returns
dividend yield
yield on cost
CAGR
XIRR
volatility
dozens of allocation percentages
multiple benchmarks
numerous charts
None of those measurements is inherently unnecessary. But every additional metric should have a purpose. Ask:
If the answer is unclear, the metric may be adding complexity rather than insight.
This is particularly important with dashboards.
A visually impressive dashboard can display an enormous amount of portfolio information while still failing to highlight the few things that actually require attention. Better analysis therefore does not mean:
More Data → More Metrics → More Charts
It means:
Relevant Data → Context → Insight → Decision
For a Structured Compounder, the objective is not maximum information.
It is decision-useful information.
Turning Portfolio Analysis Into Better Investment Decisions
Portfolio analysis has little value if it ends with observation. The final step is deciding whether the evidence requires action. A useful review process might identify:
Performance:One group of holdings generated a disproportionate share of recent returns.
Allocation:Those holdings are now materially above their intended portfolio weight.
Exposure:Several ETFs increase exposure to the same companies.
Concentration:The portfolio is more dependent on one sector than the headline number originally suggested.
The investor can then ask:
Is this concentration intentional?
Has my investment thesis changed?
Should new contributions be directed elsewhere?
Does my target allocation still reflect my strategy?
Is rebalancing necessary?
Or is doing nothing currently the most rational decision?
That last question matters.
Good portfolio analysis does not exist to create more trading. Sometimes the correct conclusion is:
No action required.
The purpose is to make that decision consciously. This creates the complete analytical process:
Record → Measure → Compare → Analyse → Decide → Review
Excel supports each stage.
But the spreadsheet itself is not the investment system.
The system is the repeatable process through which information becomes a decision.
That is the transition at the heart of this guide. Most investor spreadsheets are already capable of recording enormous amounts of information.
A Structured Compounder goes further.
They build a portfolio analysis process that helps them understand what that information means, how the different parts connect and whether anything genuinely needs to change.

Real Investor Case Study (Bangalore, India 🇮🇳) — The Spreadsheet That Knew Everything Except What to Do Next
This Investor was a 44-year-old technology executive in Bangalore who had tracked his investments in Excel for more than a decade.
His spreadsheet was sophisticated.
It measured performance, CAGR, dividends, allocation, sector and geographic exposure, and investments across multiple accounts.
Almost every conventional measure looked healthy. Yet whenever new money became available, Arjun still found himself asking:
“What should I buy next?”
So rather than adding another metric, the review asked a different question:
What The Review Revealed
We reviewed the Investor's recent investment decisions using a simple sequence:
A pattern quickly appeared.
The Investor researched individual investments carefully. But most decisions started with an attractive stock or ETF rather than with the needs of his existing portfolio.
One ETF duplicated exposure he already held elsewhere.
Another purchase increased an already overweight sector.
Regular contributions frequently went towards whichever investment currently looked most attractive.
His spreadsheet identified all of this. But usually after the investment had been made. The problem wasn’t the quality of his data. It was when he was using it.
The Real Issue
The Investor didn’t need a more sophisticated spreadsheet. He needed to reverse his decision process. His existing approach was:
Investment Idea → Research → Buy → Analyse Portfolio Effect
The structured approach became:
Analyse Portfolio → Identify Need → Evaluate Options → Decide
That changed the question from:
“Is this a good investment?”
to:
“What would this investment do to the portfolio I already own?”
Both questions matter. But the second is what turns investment research into portfolio analysis.
What Changed
The Investor added a simple pre-investment review. Before committing significant new capital, he asked:
What exposure would this investment add?
What would it duplicate?
How would it change allocation or concentration?
Why does the portfolio need it?
He didn’t rebuild his spreadsheet.
He actually began making fewer investment decisions.
Sometimes new money was better directed towards an existing underweight holding.
Sometimes the portfolio needed nothing at all.
The breakthrough came from adding almost no new data. It came from changing when he used the data he already had. His process moved from:
Record → Measure → Compare → Analyse
to:
Record → Measure → Compare → Analyse → Decide
That is the purpose of structured portfolio analysis. Not simply to explain the portfolio you have already built. But to improve the decisions that determine what you build next.
Portfolio Tracking vs Structured Portfolio Analysis
Portfolio tracking and portfolio analysis use much of the same information.
The difference is what happens next.
Portfolio Tracking | Structured Portfolio Analysis |
Records what you own | Examines what the holdings collectively create |
Shows portfolio value | Explains what is driving changes in value |
Calculates investment returns | Interprets returns against contributions and benchmarks |
Shows current allocation | Compares allocation with targets and identifies drift |
Records individual ETFs | Examines underlying exposure and overlap |
Tracks individual accounts | Consolidates accounts into one portfolio |
Displays portfolio metrics | Connects metrics to reveal relationships |
Helps you see the portfolio | Helps you decide what the portfolio needs |
Both are important. You cannot analyse a portfolio effectively without accurate tracking underneath it. But a Structured Compounder goes beyond asking:
“What does my spreadsheet show?”
They ask:
“What does this information mean, how does it connect, and should it influence my next decision?”
Common Portfolio Analysis Spreadsheet Mistakes
A portfolio spreadsheet can become increasingly sophisticated without necessarily producing better analysis. Common mistakes include:
tracking portfolio growth without separating contributions from investment returns
calculating performance without appropriate context or benchmarks
measuring current allocation without comparing it with targets
analysing individual holdings while ignoring portfolio-wide concentration
treating ETFs as single investments without considering underlying exposure
reviewing investment accounts separately rather than consolidating them
collecting metrics that have no clear connection to an investment decision
creating dashboards that display information without highlighting what requires attention
analysing portfolio changes only after investment decisions have been made
assuming that more data automatically means better analysis
The final mistake is particularly important.
Portfolio analysis isn’t a competition to build the most complicated spreadsheet.
Every calculation should help you understand something meaningful about the portfolio.
If it doesn’t, it may be adding information without adding insight.
Quick Portfolio Analysis Audit
Ask yourself:
✓ Can I distinguish portfolio growth from actual investment performance?
✓ Can I explain what has driven my returns?
✓ Can I compare actual allocation with my intended allocation?
✓ Can I identify concentration across holdings, sectors and geographies?
✓ Do I understand the underlying exposures within my ETFs?
✓ Can I see every investment account as part of one consolidated portfolio?
✓ Can I identify relationships between performance, allocation and exposure?
✓ Does my spreadsheet highlight information that may require a decision?
✓ Do I use portfolio analysis before making significant new investment decisions?
✓ Can I explain what my portfolio currently needs rather than simply what I want to buy next?
If several answers are “No”, your spreadsheet may be doing a better job of recording your investments than analysing them.
The objective isn’t to answer every possible portfolio question.
It is to answer the questions that improve your investment process.
Who This Guide Is For
This guide is designed for investors who already track their investments but want to understand their portfolio more deeply. It is particularly valuable if you:
use Excel or another spreadsheet to manage your investments
already track holdings, values, returns or dividends
want to understand what is actually driving portfolio performance
want to analyse allocation, concentration and portfolio drift
own ETFs and want greater visibility of underlying exposure
manage investments across multiple accounts
have accumulated substantial portfolio data but aren’t sure how to use it
want analysis to influence investment decisions rather than simply document them
are building a more structured long-term investment process
are progressing towards becoming a Structured Compounder
You don’t need a highly complex workbook.
You need a spreadsheet that helps you move from:
Data → Context → Insight → Decision
Who This Guide Is NOT For
This guide is unlikely to be useful if you:
are looking for individual stock or ETF recommendations
want short-term market predictions
primarily use spreadsheets for active trading
simply want to monitor daily portfolio movements
want to add as many investment metrics as possible
expect Excel to make investment decisions for you
It also isn’t an argument that every investor needs sophisticated portfolio analysis. A simple portfolio may require a relatively simple system.
The objective is not complexity.
It is to understand enough about your portfolio to make deliberate, informed and repeatable decisions.
Discover What Your Portfolio Analysis Reveals About You
Most investors who analyse their portfolios already track substantial amounts of information. They can see:
Individual holdings
Portfolio value
Investment performance
Asset allocation
Sector and geographic exposure
Yet many still cannot answer some of the most important questions about their portfolio.
What is actually driving my portfolio performance?
Where is concentration developing across holdings, ETFs and accounts?
Are the different metrics in my spreadsheet helping me make better investment decisions?
What stage of the Investor Progression Model am I currently at?
What should I change to become a more structured long-term investor?
Your spreadsheet may already contain everything you need. But having portfolio data isn’t the same as understanding what that data collectively reveals. The Free Investor Assessment helps identify:
hidden weaknesses in how you analyse your portfolio
your current Investor Progression Model stage
portfolio analysis blind spots affecting long-term decisions
opportunities to build a more structured investment system
practical next steps towards becoming a Structured Compounder
Because the strongest investors don’t simply collect more portfolio information.
They understand how that information connects and what it should tell them about their next decision.

FAQ
What is portfolio analysis in Excel?
Portfolio analysis in Excel uses investment data to understand performance, allocation, concentration, diversification, exposure and other characteristics of your overall portfolio.
Rather than simply recording investments, the objective is to interpret what the information means and whether it should influence future decisions.
What should a portfolio analysis spreadsheet include?
A useful spreadsheet may include:
holdings and current values
contributions and withdrawals
dividends
portfolio returns
CAGR or other relevant return calculations
target and actual allocation
sector and geographic exposure
concentration
ETF exposure
The exact structure should reflect the questions you need the spreadsheet to answer.
What is the difference between portfolio tracking and portfolio analysis?
Portfolio tracking records what happened. Portfolio analysis examines why it happened, what it means and whether anything should change. Tracking provides the underlying data. Analysis provides context for interpreting it.
How do I analyse portfolio performance in Excel?
Start by separating investment performance from new contributions and withdrawals.
You can then use appropriate return calculations, such as total return, CAGR or XIRR, depending on the question being analysed, and compare results with a relevant benchmark where appropriate.
How do I analyse portfolio concentration?
Calculate individual holdings as percentages of total portfolio value, then aggregate investments by relevant categories such as sector and geography. For ETFs, you may also need to examine underlying holdings to identify concentration that is not visible from the fund-level allocation.
Why should multiple investment accounts be analysed together?
Because separate accounts can contain duplicated holdings and exposures. Consolidating them allows you to analyse the allocation, concentration and diversification of the complete portfolio, rather than treating administrative account boundaries as separate investment strategies.
Can Excel identify ETF overlap?
Yes, provided you have the underlying holdings data. ETF holdings can be compared with other funds and individually owned shares to identify repeated company, sector or geographic exposure.
How many portfolio metrics should I track?
There is no ideal number. A better test is:
“What does this metric help me understand or decide?”
If a metric has no meaningful role in your investment process, adding it may increase complexity without improving analysis.
How often should I analyse my portfolio?
The appropriate frequency depends on your portfolio and investment process. For long-term investors, the objective is generally a repeatable review process rather than constant monitoring. Significant contributions, allocation changes or investment decisions may also justify additional analysis.
Does better portfolio analysis mean making more changes?
No. Better analysis should improve the quality of decisions—not increase their frequency. Sometimes the most useful conclusion from a portfolio review is: No action required.

Understand what is actually driving portfolio growth by separating investment performance, contributions, dividends and return calculations.
Look beneath fund names to identify hidden company, sector and geographic exposure across your ETFs.
See what changes when investments held across separate accounts are consolidated and analysed as one portfolio.
Understand why complete portfolio visibility requires more than simply seeing every holding, value and conventional classification.
Connect target allocation, actual allocation, portfolio drift and investment decisions within a structured allocation system.
Final Thought
Most investors don’t suffer from a shortage of portfolio information. They suffer from a shortage of connection between the information they already have. A spreadsheet can tell you what you own.
It can calculate returns.
It can measure allocation.
It can record dividends.
It can show sector exposure, geographic exposure and account values.
But each number becomes considerably more useful when you understand how it relates to the others.
Strong performance can create concentration.
Concentration can change allocation.
ETF overlap can increase exposure.
Multiple accounts can hide all three.
And new contributions can either correct those changes or reinforce them.
That is why portfolio analysis is different from portfolio tracking. The objective isn’t simply to create a more sophisticated record of your investment history. It is to build a process that moves from:
Record → Measure → Compare → Analyse → Decide → Review
Sometimes that analysis will lead to a change.
Sometimes it will confirm that nothing needs to change at all.
Both are valuable outcomes.
Because the purpose of portfolio analysis isn’t to create more activity.
It is to create better-informed decisions.
And that is one of the defining transitions towards becoming a Structured Compounder.
