How Do I Know If My Stock Picks Are Any Good?

Short answer

To judge your stock picks fairly, compare every pick, including the ones you sold and the ones you would rather forget, against what the same money would have done in a simple alternative, such as an index fund or leaving the portfolio unchanged. Remembering the winners and forgetting the losers makes most investors feel better than their results. Look at the whole record over enough time, check whether each pick worked for the reason you gave when you bought it, and separate the returns you earned from picking from the returns the market handed everyone.

Most people who pick individual stocks have a sense of how they are doing, and that sense is usually built from the picks they remember best. A fair evaluation needs the whole record and a fair comparison. This page walks through how to judge your own stock picking honestly: which benchmark to use, why every pick counts, how to tell a good process from a lucky outcome, and how to score each decision automatically.

Count every pick, not just the memorable ones

Memory favours winners and quietly drops the stocks sold at a loss or held and forgotten. An honest evaluation lists every buy and sell over the period, including positions that are no longer in the portfolio. Without the full list, any conclusion is built on a selection of your own results.

Choose a fair comparison

Rising with the market is not the same as picking well. A fair benchmark is what the same money would have done in a simple alternative with similar risk: a broad index fund, or your own portfolio left unchanged. If your picks were mostly technology stocks, comparing them to a broad index in a strong technology year can flatter or punish you for the sector, not the selection.

Separate process from outcome

A pick can work for reasons unrelated to why you bought it, and a sound pick can lose money. Checking each decision against the thesis you wrote when you made it tells you whether your reasoning is being rewarded or whether results are coming from somewhere else. A decision journal makes this possible; without one, hindsight rewrites the reasons.

Give it enough time and enough picks

A handful of picks over a single year says very little. Short periods are dominated by market moves, and a few large winners or losers can swing the whole result. Look across many decisions and several market conditions before drawing a conclusion about skill.

Score each decision automatically

Pure Benchmarks, our own product, does this from connected holdings. Its Decision Benchmark compares your actual portfolio with the buy-and-hold counterfactual, the do-nothing portfolio you would have had without each change, and scores every buy and sell against it. It also ranks your portfolio against verified investors in the same risk category, which shows how your results compare with people taking similar risk.

Your current platform won't show you how your portfolio ranks against real investors in the same risk category. Create your secure Pure Benchmarks account and see exactly where you stand.

Frequently asked questions

How do I know if I am good at picking stocks?

Compare every pick over a meaningful period against what the same money would have done in a simple alternative with similar risk, and check whether the picks worked for the reasons you gave.

What benchmark should I compare my stock picks to?

Use an alternative with similar risk: a broad index fund, a relevant sector fund, or your own portfolio left unchanged. The S&P 500 is not always the right comparison for a portfolio that looks different from it.

How many stock picks do I need before I can judge my skill?

There is no fixed number, but a few picks over one year are dominated by market moves and luck. More decisions across different conditions give a much clearer picture.

Should I include stocks I already sold?

Yes. Leaving out sold positions, especially losing ones, is the most common way investors overestimate their results.

Is there a tool that scores my individual stock picks?

Pure Benchmarks, our own product, scores each buy and sell against the do-nothing baseline from connected holdings. This page is information for comparison and not a recommendation about any holding.
