How to Measure Your Own Portfolio Performance: 5 Basic Metrics & How to Compare Against the Index

Tell me if this sounds like you. You have been investing on Bursa Malaysia for a few years. You know your portfolio "is up" or "is down" — but if asked what percentage return you have made per year, or whether your portfolio is beating the FBM KLCI, you stumble. Most retail investors are in this situation. They know what their portfolio is worth today, but have no idea whether their performance is actually good or bad.
The problem is, without measuring properly, you cannot know if your strategy is working. You may feel "good" because your portfolio is up in a bull market — but the market may be up even more, meaning you are actually lagging. Or you may feel "bad" because your portfolio is down in a bear market — but it may be down less than the market, meaning your strategy is actually working.
This article explains a simple, practical way for retail investors to measure their own portfolio performance on Bursa Malaysia. No crazy formulas you need a fund manager to understand — just 5 basic metrics, free tools you can use, and a few common mistakes you should avoid.
Short Answer
For retail investors, measure portfolio performance with 3 basic steps: calculate annualised total return (CAGR), compare against a benchmark index (FBM KLCI or FBM 100), and track maximum drawdown. Do this at least quarterly. If your CAGR beats the index after 3-5 years and your drawdown does not exceed 25%, your strategy is working.
Why "Just Looking at Portfolio Value" Is Not Enough
This is the biggest mistake. Many investors open their brokerage app, look at the total portfolio value for the day, and feel satisfied if the number is higher than last month. But the "portfolio value" number alone is misleading, because it mixes several different things together.
First, it does not distinguish between returns from investments and new money you have put in. If you added RM5,000 in capital last month, of course your portfolio value goes up — but that is not because your stocks worked well. It is because you added money.
Second, it does not account for dividends you have already received and spent (or withdrawn) versus dividends you have reinvested. A high-dividend portfolio may look "stagnant" in terms of price, but is actually generating good returns through cash flow.
Third, it does not give you context. Up 8% a year sounds good — until you know the market went up 15% in the same year. Without a benchmark, you cannot tell whether you are beating, matching, or lagging the market.

5 Basic Metrics for Measuring Portfolio Performance
Here are the metrics you need to track. None require a finance degree — just Google Sheets or Excel.
1. Total Return
Total return = (Ending value - Starting value + Dividends received) / Starting value × 100%.
Simple example: You start the year with RM50,000 portfolio in January. By December, the portfolio is worth RM55,000 and you received RM1,500 in dividends throughout the year. Total return = (55,000 - 50,000 + 1,500) / 50,000 = 13%.
The key point: new money you added during the year is NOT counted as a return. If you added RM10,000 in capital in June, you need to adjust the calculation. Easy approach for investors who add capital regularly (DCA, say): use time-weighted return (see the section below).
2. CAGR (Compound Annual Growth Rate)
CAGR gives you the average annual return — but accounting for the effect of compounding. It is the industry-standard metric for comparing long-term investment performance.
Formula: CAGR = (Ending Value / Starting Value)^(1/n) - 1, where n = number of years.
Example: Your portfolio was RM30,000 in 2020 and RM48,000 in 2025 (5 years). CAGR = (48,000/30,000)^(1/5) - 1 = 9.86% per year.
CAGR lets you compare investments over different time periods fairly. For a deeper understanding of CAGR and when it misleads, read What Is CAGR? Formula, Calculation Examples & Why Every Investor Needs to Know.
3. Return vs Benchmark (FBM KLCI or FBM 100)
The single most important metric for individual stock investors on Bursa Malaysia: are you beating the index?
Common benchmark indices for Bursa Malaysia investors:
- FBM KLCI — the 30 largest companies (Maybank, CIMB, Tenaga, etc.)
- FBM 100 — the 100 most liquid companies (KLCI + Mid 70 combined)
- FBM Emas Shariah — if you are a shariah-compliant investor
How to calculate: take the index value at the start of the period, the value at the end of the period, calculate the index's % return. Compare with your portfolio's % return.
Example: FBM KLCI 1,500 → 1,650 in one year = +10%. Your portfolio +13%. You beat the index by 3 percentage points (alpha = +3%).
Important: If your performance consistently lags the index over 3-5 years, be honest with yourself. You may be better off buying an index ETF (like the FBMKLCI ETF) and getting market returns at low cost, rather than trying to "pick your own stocks" but underperforming.
4. Maximum Drawdown
Maximum drawdown = the percentage decline from peak to trough in a given period.
Example: Your portfolio reaches RM60,000 in March. Then drops to RM48,000 in September. Drawdown = (60,000 - 48,000) / 60,000 = 20%.
Why does this metric matter? Because it shows the real risk of your portfolio — not just returns. Two portfolios can have the same annual return, but one may go through a 40% drawdown (hard to bear emotionally) while the other only 15%. The second is actually better risk management.
A healthy maximum drawdown for retail investors: less than 25% in normal market conditions, and less than 35% even in a severe bear market.
5. Win Rate & Average Size of Wins vs Losses
For active investors who buy and sell stocks, two metrics are useful:
Win rate = the percentage of trades that turn out profitable. Example: 60 out of 100 trades profitable = 60% win rate.
Average size of wins vs losses = average profit per winning trade divided by average loss per losing trade.
You can have a low win rate and still win big — if each win is much bigger than each loss. Conversely, a win rate of 80% but each loss is twice the size of each win = you can still end up losing overall.

Time-Weighted vs Money-Weighted Return
If you never added capital after starting to invest, total return is easy to calculate. But most retail investors invest regularly (monthly DCA, or occasional top-ups). This is the issue — what is your "real" return?
Time-weighted return (TWR) ignores the timing of capital additions. It measures the performance of your investment decisions alone. How to calculate: break the period into sub-periods every time there is a capital addition/withdrawal, calculate the return of each sub-period, then compound. This is the metric professional funds use for benchmarking.
Money-weighted return (MWR / IRR) takes into account the size and timing of cash flows. It measures the actual return you got from your personal perspective. The IRR() or XIRR() function in Excel calculates this for you.
For an ordinary retail investor, MWR (XIRR) is more personally relevant. But for comparing your strategy with a fund manager or index, TWR is fairer. Many brokers and investment apps now display both.
Tools for Tracking Portfolio Performance
You do not need an expensive system. Options for Malaysian investors:
Bursa Anywhere app — Bursa Malaysia's official app. Shows your portfolio value and transactions, but not much performance analysis.
ShareInvestor (subscription) — displays portfolio return, comparison with index, and a few other metrics. Paid.
Google Sheets / Excel — most flexible and free. You can build your own template with XIRR() formulas for MWR, or use templates shared in Malaysian investor communities. Suitable for those serious about controlling their own calculations.
Your broker's app — most platforms like M+ Online already show basic return numbers, although most do not compute CAGR or do benchmark comparison automatically.
Watching the economic news calendar also helps you understand when markets make big moves (which will affect your portfolio drawdown) — we list the important dates in Economic Calendar for Bursa Investors.
When & How Often to Review
Appropriate frequency depends on your investor type:
Long-term (buy & hold) investors: Quarterly (every 3 months) is enough to check value and metrics. An annual deeper review for benchmark comparison and adjusting allocation if needed.
Active investors / swing traders: Monthly for key metrics, quarterly for overall strategy review.
What NOT to do: Check your portfolio every day. This only triggers emotion — panic when the market drops, FOMO when it rises. Excessively frequent reviews have been statistically shown to reduce investor returns.

5 Common Mistakes When Measuring Performance
Mistake 1: Not adjusting for new capital added. If you added RM10k this month, your "return" looks high — but that is actually new money, not investments working. Always separate investment returns from added capital.
Mistake 2: Ignoring dividends. Bank and REIT stocks may "not move much in price" but pay 5-7% dividends per year. Without including dividends in the calculation, you underestimate the real performance.
Mistake 3: Comparing with the wrong benchmark. Comparing a portfolio full of small-caps to FBM KLCI (which is large-cap) is not fair. Pick a benchmark that matches your portfolio's composition — perhaps FBM 100 or FBM Mid 70.
Mistake 4: Forgetting that short periods mislead. A 30% return in 6 months can be luck, not skill. The minimum period to assess performance meaningfully: 3 years, ideally 5 years. Short periods are dominated by market luck.
Mistake 5: Focusing only on returns and forgetting risk. A 20% annual return with a 50% drawdown is a portfolio many people cannot bear emotionally. A 12% annual return with a 15% drawdown may be more meaningful — more sustainable for the long run.
FAQ
1. How often should I calculate portfolio performance? For long-term investors, quarterly (every 3 months) is enough. For active investors, monthly. Avoid daily checking — it only triggers emotion without adding value.
2. Is a benchmark like FBM KLCI always fair? Not necessarily. FBM KLCI represents the 30 largest companies — if your portfolio is full of small-cap or tech stocks, it is not a suitable benchmark. Pick an index closest to your portfolio's composition.
3. What is "alpha" in performance measurement? Alpha = the difference between your portfolio's return and the benchmark's return over the same period. Positive alpha = you beat the market. Negative alpha = you lagged. Professional investors are very focused on alpha.
4. Should I count returns including or excluding dividends? MUST include dividends. Returns without dividends are half-returns only. The proper format: "total return" which accounts for capital gains + dividends received.
5. If I lose every year, should I stop? Depends on context. If you lose in a bull market that generated 15% a year, yes — your strategy may not be working. But if you lose 10% in a market that fell 20%, you actually outperformed — your strategy may be effective at risk management, wait for the market to reverse.
6. What CAGR is "good" for a Bursa Malaysia portfolio? For reference: FBM KLCI generates a CAGR of around 4-6% per year over the past decade. Retail investors who can achieve 8-10% after fees and tax already outperform the market. Consistent returns of 15%+ are excellent — but be wary of such claims if not over long periods and not audited.
7. What is the main difference between TWR and MWR? TWR (time-weighted) ignores the timing of capital additions — it measures the performance of investment decisions. MWR (money-weighted / XIRR) takes cash flows into account — it measures actual personal returns. Professional funds use TWR for fair comparisons; retail investors find MWR more relevant.
8. Should I calculate after brokerage fees and dividend tax? Yes, for the real picture. "Gross" returns before fees always look better than reality. Calculate net returns after transaction fees, CDS clearing fees, and dividend tax if applicable (10% for foreign stocks, for example).
Conclusion
Measuring portfolio performance is not rocket science — it is a basic discipline every retail investor should practise. Five simple metrics — total return, CAGR, return vs benchmark, maximum drawdown, and win rate — already give you a clear picture of whether your strategy is working. The key: be honest with yourself, use the appropriate benchmark, and give it at least 3-5 years before drawing conclusions about your strategy.
Without measurement, you are just reacting on feeling — and in investing, feeling is the worst possible advisor.
To start investing with discipline you can measure, you need a platform that gives you exposure to stocks on Bursa Malaysia and overseas, with access to performance metrics.
Open a CDS and trading account to start investing in stocks on Bursa Malaysia as well as foreign markets such as the United States and Hong Kong through a single platform.
