You open your investment account.

You see:

+$2,350

Your first reaction is:

“Great! I’m making money.”

But wait.

Are you really doing well?

Maybe your portfolio is up 8%.

That sounds good.

But what if a comparable investment gained 15% during the same period?

Now the question changes.

You didn’t simply need to know whether your portfolio made money.

You needed to know whether the return was good relative to the risk you took and the alternatives available to you.

That is the foundation of objective investment analysis.

Instead of asking:

“Am I making money?”

start asking:

“Is my portfolio producing an appropriate return for the amount of risk I am taking?”

This article will show you how to analyse your investments using a practical framework designed for investors in the United States.

1. Start With the Most Basic Number: Your Total Return

The first step is determining how much your investment actually gained or lost.

Imagine you invested:

$10,000

Your investment is now worth:

$11,500

Your simple gain is:

$1,500

Your simple return is:

15%

The basic formula is:

Return = (Ending Value − Starting Value) ÷ Starting Value × 100

Example

That is useful.

But there is a problem.

Most real portfolios involve deposits, withdrawals and dividends.

That makes performance more complicated.

2. Don’t Confuse Deposits With Investment Returns

Imagine you started with:

$10,000

One year later, your account shows:

$20,000

You might think:

“I made $10,000!”

But what if you deposited another $8,000 during the year?

Your actual investment gain was closer to:

$2,000

This is why you need to distinguish between:

Money you contributed

and

Money your investments generated.

Portfolio Contribution Tracker

The change in your account balance is not necessarily your investment return.

3. Understand Your Actual Rate of Return

If you regularly add money to your investments, a simple return calculation can become misleading.

This is where concepts such as time-weighted return and money-weighted return/internal rate of return (IRR)become useful.

Time-Weighted Return

Time-weighted return is designed to evaluate the performance of the investments themselves while reducing the impact of the timing of your own deposits and withdrawals.

It can be useful when evaluating an investment manager or strategy.

Money-Weighted Return

Money-weighted return takes into account when you personally put money into or withdrew money from the portfolio.

This can be more useful for answering:

“How well did my actual money perform?”

For a personal investor, this distinction matters because adding a large amount of money immediately before a market decline can make your personal return look very different from the investment’s return over the same period.

4. Compare Your Portfolio With a Benchmark

This is one of the most important steps.

Suppose your portfolio returned:

10%

Is that good?

You need context.

Imagine the relevant benchmark returned:

15%

Now your 10% looks less impressive.

On the other hand, if the benchmark returned:

4%

your 10% may look much better.

The Benchmark Test

This is why:

Return without context is incomplete information.

5. Which Benchmark Should You Use?

The benchmark should match the investment you are evaluating.

For example:

US Large-Cap Stocks

A broad large-cap US equity benchmark may be appropriate.

The S&P 500 is commonly used as a reference point for large US companies.

US Small-Cap Stocks

A small-cap benchmark may be more appropriate.

International Stocks

Use a relevant international or global benchmark.

Bonds

Compare with an appropriate bond-market benchmark rather than a stock index.

Real Estate

A relevant real estate benchmark may be more useful.

The mistake is comparing everything with the S&P 500.

Your portfolio does not necessarily need to beat the S&P 500.

It needs to be evaluated against a benchmark that makes sense for its strategy and risk level.

6. Your Portfolio vs the S&P 500

Let’s imagine:

Your portfolio: +9%

S&P 500: +12%

You underperformed by:

3 percentage points

But does that mean your portfolio is bad?

Not necessarily.

Imagine your portfolio contains:

• US stocks
• International stocks
• Bonds
• Cash

Meanwhile, the S&P 500 contains US large-cap stocks.

The two portfolios have different objectives.

Your diversified portfolio may have lower volatility and lower downside risk.

That is why you need to compare both return and risk.

7. Look at Risk, Not Just Return

Imagine two investments.

Investment A

Return:

12%

Maximum decline:

−35%

Investment B

Return:

10%

Maximum decline:

−12%

Which is better?

There is no universal answer.

But Investment B may be more attractive to an investor who values stability and cannot tolerate large losses.

This is why a good portfolio analysis includes:

Return + Risk + Time Horizon

8. What Is Volatility?

Volatility describes how much an investment’s price fluctuates.

An investment that moves:

+2%, −1%, +3%, −2%

is relatively less volatile than one that moves:

+15%, −20%, +25%, −18%

even if both eventually produce the same long-term return.

High volatility isn’t automatically bad.

But you need to know whether you are comfortable with it.

9. Measure Maximum Drawdown

One of the most useful risk measurements for ordinary investors is maximum drawdown.

It measures the largest decline from a previous peak during a particular period.

Imagine your portfolio reaches:

$100,000

Then falls to:

$75,000

Your drawdown is:

−25%

Later, it recovers to $100,000.

You did not permanently lose money if you held through the recovery.

But you experienced a 25% decline.

That matters because investors often underestimate how difficult it is psychologically to watch a portfolio fall.

Drawdown Tracker

This gives you a much clearer picture of the ride your money experienced.

10. Understand the Power of Losses

Losses have an unusual mathematical effect.

If an investment falls:

50%

you do not need a 50% gain to recover.

You need a:

100% gain

to return to the original value.

Example

$10,000

↓

−50%

↓

$5,000

↓

+100%

↓

$10,000

This is why avoiding catastrophic losses can be extremely important.

11. Analyse Your Investments Individually

Don’t analyse only your entire portfolio.

Look at each investment.

Create a table like this:

Now you can ask better questions.

12. Why Do You Own Each Investment?

This may be more important than its recent return.

Every investment should have a reason for being in your portfolio.

For example:

Investment A: long-term growth

Investment B: diversification

Investment C: income

Investment D: inflation protection

Investment E: speculative opportunity

If you cannot explain why you own something, that’s a warning sign.

You may be holding it simply because:

“It went up before.”

That is not an investment strategy.

13. The “Would I Buy It Today?” Test

Here’s a powerful psychological test.

Imagine you own a stock today.

It has fallen 20%.

Ask yourself:

“If I didn’t already own this investment, would I buy it today at the current price?”

If the answer is no, ask:

Why am I still holding it?

Maybe your investment thesis has changed.

Maybe the company fundamentals have deteriorated.

Or maybe you’re simply emotionally attached to the investment.

This question can expose loss aversion and emotional decision-making.

14. Don’t Fall in Love With Your Investments

Investors sometimes say:

“I believe in this company.”

That’s fine.

But belief is not analysis.

A company can be excellent and still be a bad investment if you pay too much for it.

Ask:

Is the business improving?

Are revenues growing?

Are profits improving?

Is debt manageable?

Is the valuation reasonable?

What could go wrong?

15. Analyse Company Fundamentals

If you own individual stocks, look at the underlying business.

Important metrics can include:

Revenue Growth

Is the company generating more sales?

Earnings

Is profitability improving?

Free Cash Flow

Is the business generating cash after necessary capital spending?

Debt

Does the company carry manageable debt?

Margins

Is the company becoming more or less efficient?

Valuation

Are you paying a reasonable price relative to the company’s financial performance and prospects?

No single metric should determine your decision.

16. Look at Fees

Fees are easy to ignore because they often appear small.

But they compound over time.

Imagine two investments generate similar gross returns.

One has very low costs.

The other has substantially higher annual expenses.

Over decades, the difference can become meaningful.

Fee Comparison

Always understand:

What am I paying?

and:

What am I receiving for that cost?

17. Consider Taxes

For investors in the United States, investment returns should also be considered after taxes when appropriate.

Different accounts and investments can receive different tax treatment.

For example, investors may have:

• Taxable brokerage accounts
• Traditional IRAs
• Roth IRAs
• Employer-sponsored retirement plans

Capital gains, dividends, interest and distributions can have different tax consequences depending on the investment and account.

Therefore:

A 10% pre-tax return is not necessarily equivalent to a 10% after-tax return.

Tax considerations can be especially important when comparing investments held in taxable accounts.

18. Inflation Matters

Imagine your investment grows:

4%

but inflation is:

3%

Your nominal return is 4%.

But your purchasing power has increased by much less.

A simplified approximation is:

Real return ≈ nominal return − inflation

So:

4% − 3% ≈ 1%

The exact calculation is slightly different, but the concept is important.

Your goal is not simply to make your account balance larger.

Your goal is to increase your purchasing power over time.

19. Analyse Your Portfolio’s Diversification

Imagine you own ten different stocks.

That sounds diversified.

But what if all ten companies are technology companies?

You may have ten investments but essentially one major economic bet.

Diversification means spreading exposure across different investments and risk sources.

Consider:

• Companies
• Industries
• Asset classes
• Geographic regions
• Investment styles

Diversification Spreadsheet

20. Check for Concentration Risk

You may think you have a diversified portfolio.

But perhaps one stock represents:

35%

of your entire portfolio.

That’s significant concentration.

Calculate:

Investment value ÷ total portfolio value × 100

Example

$30,000 in one stock

÷

$100,000 portfolio

=

30%

That means one company determines a large part of your financial outcome.

21. Compare Your Portfolio With Your Goals

A portfolio should serve a financial purpose.

Your goal could be:

Retirement

Buying a home

Education

Financial independence

Building wealth

Generating income

The appropriate investment strategy depends heavily on the goal and time horizon.

Imagine you need $50,000 in two years.

Investing that money in a highly volatile asset could create a serious problem if the market falls immediately before you need the cash.

The question isn’t:

“What’s the highest-return investment?”

It’s:

“What’s an appropriate strategy for this specific goal?”

22. Use Different Time Horizons

Never judge a long-term investment solely on a few weeks of performance.

Analyse:

1 month

3 months

1 year

3 years

5 years

10 years, where appropriate.

Short-term results can be heavily influenced by market noise.

Longer periods can provide more meaningful context, although they do not guarantee future performance.

Performance Tracker

23. What About Dividends?

Suppose a stock price stays exactly the same.

You buy it for:

$10,000

At the end of the year, it is still worth:

$10,000

But you received:

$400 in dividends.

Your total return was not zero.

It was approximately:

4%

before considering taxes and other factors.

Therefore, when comparing investment performance, use total return where appropriate rather than looking only at price changes.

24. Reinvested Dividends Matter

If dividends are reinvested, they can purchase additional shares.

Those additional shares can potentially generate more dividends and participate in future price changes.

This creates another form of compounding.

Over long periods, reinvestment can significantly affect total wealth accumulation.

25. Don’t Judge an Investment Only by Its Last Year

Imagine an investment produced:

−15%

last year.

That doesn’t automatically make it a bad investment.

Maybe:

3-year annualised return = 12%

5-year annualised return = 11%

The recent decline could simply be part of normal market volatility.

On the other hand, a company with a long history of declining fundamentals may deserve serious reconsideration.

Context matters.

26. The Investment Thesis Test

For every major investment, write down:

Why did I buy it?

What do I expect to happen?

What would prove me wrong?

What is my time horizon?

What is the biggest risk?

What would make me sell?

This turns investing from an emotional activity into a process.

27. Create a “Sell Rules” Document

Before a crisis happens, decide what would cause you to reconsider an investment.

For example:

Business fundamentals deteriorate significantly

Debt becomes unsustainable

Investment thesis changes

Valuation becomes extremely disconnected from fundamentals

My financial circumstances change

These rules should be based on your investment strategy rather than daily emotions.

28. Your Monthly Investment Review

You do not need to obsess over your portfolio every day.

A monthly or quarterly review may be more useful for many long-term investors.

Monthly Review

29. Your Complete Investment Scorecard

Now let’s build a simple scorecard.

Give each category a score from 1 to 10.

This isn’t a professional investment rating system.

It is a tool for forcing yourself to examine the entire picture.

30. How to Interpret Your Score

80–100

Your portfolio may have a strong overall structure, although it still requires ongoing review.

60–79

There may be areas worth investigating.

40–59

Your portfolio may have meaningful weaknesses in risk, diversification or strategy.

Below 40

Stop and conduct a deeper review before increasing your exposure.

The score is not a prediction of future returns.

It is simply a structured way to identify questions.

31. The Cold Investment Analysis Formula

When analysing an investment, forget:

“I like it.”

“Everyone is buying it.”

“My friend recommended it.”

“It used to be worth more.”

Instead, ask:

Return

What has it actually returned?

Benchmark

How did it perform relative to an appropriate benchmark?

Risk

How much volatility and drawdown did I experience?

Fundamentals

Is the underlying asset improving or deteriorating?

Cost

How much am I paying?

Taxes

What is my after-tax outcome?

Diversification

Does this increase or reduce concentration?

Goal

Does this investment help me achieve my financial objective?

Future

Would I buy it today based on what I know now?

That is what objective analysis looks like.

32. A Complete Portfolio Spreadsheet

Use this as your master investment spreadsheet.

Update it periodically.

Over time, this spreadsheet can become your personal investment dashboard.

33. The “Cold Room” Exercise

Imagine that tomorrow morning you wake up and all your investments have been converted into cash.

You have the same amount of money.

Now you have to rebuild your portfolio from zero.

Ask yourself:

Would I buy the same investments again?

Would I use the same allocation?

Would I take the same amount of risk?

Would I keep the same individual stocks?

Would I hold the same amount of cryptocurrency?

Would I use the same funds?

If your answer is different from your current portfolio, investigate why.

This exercise helps separate:

investment conviction

from

emotional attachment.

34. The Three Numbers Every Investor Should Know

If you want to simplify everything in this article, start with three numbers.

Number 1: Your Total Return

How much did your portfolio actually make?

Number 2: Your Maximum Drawdown

How much did you have to endure during the worst decline?

Number 3: Your Benchmark

How did you perform relative to an appropriate comparison?

Then add three questions:

Why did I earn this return?

What risks did I take to earn it?

Does the portfolio still match my goals?

That is already a powerful investment review system.

Conclusion: Stop Asking “Am I Making Money?”

One of the biggest mistakes investors make is judging their portfolio using only one question:

“Am I up?”

Being up is good.

But it isn’t enough.

A serious investment analysis should consider:

Return

Benchmark

Risk

Drawdown

Fees

Taxes

Inflation

Diversification

Concentration

Time horizon

Investment goals

Fundamentals

Behaviour

The objective is not to find a portfolio that never loses money.

That does not exist in the world of investing.

The objective is to build a portfolio whose potential returns, risks and costs make sense for your financial goals.

And perhaps the most powerful question is this:

“Knowing everything I know today, would I still choose to own these investments?”

If the answer is yes, you have a reason.

If the answer is no, don’t ignore that feeling.

Investigate it.

Your portfolio should be based on a strategy, not on inertia.

Final Investment Review Checklist

Before making a major investment decision, ask:

☐ What is my actual return?

☐ What is my annualised return?

☐ What is my appropriate benchmark?

☐ Did I outperform or underperform it?

☐ How much risk did I take?

☐ What was my maximum drawdown?

☐ What fees am I paying?

☐ What is the tax impact?

☐ What is my real return after inflation?

☐ Is my portfolio diversified?

☐ Is any single investment too large?

☐ Do I understand every major position?

☐ Does each investment have a purpose?

☐ Has my investment thesis changed?

☐ Would I buy this investment today?

☐ Does my portfolio still match my financial goals?

If you can answer these questions honestly, you are no longer simply watching your investments.

You are analysing them.
