How do you know if your portfolio beats the market (S&P 500)?
Updated June 27, 2026 · DeepTicker
Knowing how to know if your portfolio beats the market (S&P 500) is the question that really matters, and almost no one answers it well. Most people look at "how much have I made" in euros and stop there, but that says nothing: making 15% sounds great until you discover that the S&P 500 rose 25% that year. Beating the market means getting more return than the index while taking on a reasonable level of risk, and to measure it well you need four numbers that almost no broker shows you clearly. In this guide you will see, step by step and without jargon, how to truly compare your portfolio with the index and stop fooling yourself with half-figures.
The first obstacle is that "return" is not a single number. If you put money in and take it out throughout the year —something normal—, the gross gain in euros mixes your skill with the timing of your contributions. To compare cleanly with the S&P 500 you need the TWR (Time-Weighted Return), which isolates the performance of your investment decisions from the effect of your contributions and withdrawals. It is the industry standard precisely so that the comparison is fair. Without TWR, comparing your portfolio with the index is comparing apples with oranges.
The second obstacle is risk. Beating the index one year by taking on triple the volatility is not talent, it is having rolled the dice luckily. That is why, to know whether you really beat the market, you have to adjust for risk. Two ideas come in here: alpha, which measures how much you return above the S&P 500 once the risk you take is accounted for, and Sharpe, which measures how much return you get for each unit of risk. A portfolio that returns less but with much less turbulence can be, in adjusted terms, better than one that earns more at the cost of roller coasters.
The third obstacle is luck and sample size. A good quarter does not prove skill; it could be chance. That is why it pays to measure with an anti-luck brake: the more operations and more time, the more reliable the conclusion. And it pays to look at the drawdown (the largest fall from a peak), because a portfolio that fell 50% one year and recovered is not "the same" as one that never went past -15%, even if they end up at the same point. The journey matters as much as the destination, especially for your ability to hold on without panic-selling.
DeepTicker brings all this together in My Portfolio, with professional metrics —TWR, alpha, Sharpe, drawdown— calculated and, above all, explained, without you having to know statistics. The brand idea is the usual one: a rigorous yet simple method, and since you see how each metric is calculated, you learn by using it. My Portfolio is free forever. This is not financial advice: it is giving you the dashboard that lets you judge, honestly, whether you are doing better or worse than the index.
It also pays to separate two questions people mix up: "did I make money?" and "did I beat the market?". They are different things. You could have made 8% and lost against the index if the S&P 500 did 20%; and you could have lost 3% in a terrible year and still beat the market if the index fell 12%. Beating the market is always a relative comparison, not an absolute one. This matters because it defines your real alternative: if you do not consistently and risk-adjustedly beat the index, the sensible option for many investors is simply to buy a cheap index fund. Measuring yourself well is what lets you make that decision with data instead of with pride.
Step by step
- 1
Choose the right index to compare against
It makes no sense to compare a portfolio of US tech stocks with the IBEX. The honest benchmark for most US equity portfolios is the S&P 500 (in its total return version, which includes reinvested dividends). If your portfolio is global or European, choose the index that best represents your universe. The key is to set a single benchmark before measuring and not change it afterward to look good. Always comparing against the same index is what makes the question "do I beat the market?" have a credible answer.

Calculate your real return with TWR
Forget the gross gain in euros: it mixes your decisions with the timing of your contributions. Use the TWR (Time-Weighted Return), which neutralizes the effect of putting money in and taking it out and leaves only the performance of your investments. It is the industry standard precisely to compare portfolios fairly against an index. If you contributed money just before a rise, the TWR does not "reward" you for that timing luck; it measures your selection skill. Without this step, any comparison with the S&P 500 will be biased.
- 3
Compare your TWR with that of the S&P 500 over the same period
With your TWR calculated, put it next to the TWR of the S&P 500 over the exact same period. If your portfolio did 14% and the index 11%, you are ahead on gross return; if the index did 19%, you are behind even if you made money. Be careful about comparing different periods or starting to count from your best moment. The honest comparison uses the same start and end dates. This step answers the literal question, but risk is still missing to know whether the result is skill or chance.

Adjust for risk with alpha and Sharpe
Earning more than the index by taking on much more risk is not beating the market sustainably. Alpha measures your excess return over the S&P 500 once risk is accounted for; a positive and stable alpha is the real sign of skill. Sharpe tells you how much return you get for each unit of volatility. Between two portfolios that match the index, the one with the higher Sharpe does it with fewer scares. Looking only at return without these two numbers is like judging a driver by their speed while ignoring how many times they nearly crashed.

Review the drawdown and your real tolerance
The drawdown is the largest fall from a peak to the next trough, and it measures the pain your portfolio put you through along the way. Two portfolios can end up in the same place: one fell 18% at most and another 45%. The second looks the same on paper, but it would have pushed you to sell at the worst moment. Reviewing the drawdown tells you whether your strategy is bearable for you, not just profitable. A portfolio that beats the S&P 500 but that you could not emotionally withstand is not, in practice, a portfolio you will hold on to.

Measure with enough sample and avoid self-deception
A winning quarter proves nothing: it can be luck. To know whether you beat the market reliably you need time and a reasonable number of decisions. DeepTicker incorporates an anti-luck brake that weights reliability according to the sample and penalizes large drawdowns, so you do not confuse a lucky stroke with skill. Repeat the measurement regularly —quarterly or annually— and watch the trend, not a loose data point. The consistency of alpha over time, not an isolated spike, is what truly indicates you are doing well.
Why almost no one knows if they really beat the market
Most investors answer "do you beat the market?" by looking at their balance in euros, and that is exactly what you should not do. The gain in euros mixes contributions, withdrawals, dividends and the timing of each move; it does not isolate your skill. That is why the TWR exists, which is the professional standard. The second reason for self-deception is ignoring risk: it is easy to beat the S&P 500 one year by concentrating in three volatile stocks, but that result is not repeatable and does not prove talent, only a bet. Without adjusting for risk with alpha and Sharpe, the comparison is incomplete.
The third reason is selective memory: we tend to remember the hits and forget the misses, and to start counting from our best moment. That is why it pays to have a system that measures objectively, with fixed dates and the same yardstick for your portfolio and for the index. DeepTicker calculates these metrics automatically and, importantly, explains what each one means, so you go from "I think I'm doing well" to "I'm 2% above the index with less risk and a sustained positive alpha". That difference between intuition and data is what separates the investor who improves from the one who just hopes to get lucky.
How to interpret your alpha against the S&P 500
Alpha is the metric that best answers whether you beat the market adjusting for risk. A positive alpha means you return above what could be expected given the risk you take versus the S&P 500; a negative alpha means a simple index fund would have done better for you in adjusted terms. Do not obsess over a single value: what is relevant is that the alpha is positive and stable over several periods, because that suggests skill and not coincidence.
To make it motivating and honest, DeepTicker translates that risk-adjusted skill into a system of 11 animal leagues, from 🦠 Plankton to 🐙 Kraken, with an anti-luck brake by sample size and an anti-ruin penalty for large drawdowns. This way, moving up a league is not achieved with a lucky bet, but by beating the index with consistency and risk control. It is the same underlying idea: professional-level metrics, presented clearly and even enjoyably, so anyone understands where they stand and learns to improve. Remember that this is educational information, not advice: the decision about your portfolio is always yours.
Knowing whether your portfolio beats the market (S&P 500) is not about looking at euros: it is measuring your TWR against the index, adjusting for risk with alpha and Sharpe, watching the drawdown and demanding enough sample to rule out luck. DeepTicker does all those calculations for you in My Portfolio —free forever— and explains them so you learn while using them. It is a rigorous, simple and transparent method; it is not financial advice, it is the dashboard so you can judge your own performance honestly.
Frequently asked questions
What exactly does beating the market mean?
It means getting more return than a benchmark index, such as the S&P 500, while taking on a reasonable level of risk and over the same period. Making money is not enough: you have to beat the index and, for it to count as skill, do it without taking on excessive risk.
Why is comparing the gain in euros with the index not valid?
Because the gross gain mixes your decisions with the timing of your contributions and withdrawals. To compare cleanly with the S&P 500 you use the TWR, which isolates the performance of your investments from the effect of putting money in or taking it out.
What is alpha and why does it matter more than return?
Alpha measures how much you return above the S&P 500 once the risk you take is accounted for. It matters because a high return achieved with extreme risk is not repeatable; a positive and stable alpha does suggest real skill.
How often should I compare my portfolio with the S&P 500?
The sensible thing is to review it periodically, quarterly or annually, and focus on the trend, not a loose data point. A good quarter can be luck; the consistency of alpha over time is what counts.
Is the drawdown useful for knowing if I'm doing well?
The drawdown measures the largest fall from a peak and reveals how much loss risk your portfolio endured. Two portfolios with the same final result can have very different drawdowns; the smaller one is usually more bearable and sustainable for you.
Do I need to know statistics to understand these metrics?
No. DeepTicker calculates TWR, alpha, Sharpe and drawdown and explains what each one means in plain language. Since you see how they are calculated, you learn the concepts by using the tool, without needing spreadsheets.
Is DeepTicker's My Portfolio paid?
