Social platforms give every trader a risk score, and most copiers use it like a vibe: low number good, high number scary. The score is genuinely useful — but only if you know what it measures, and more importantly, what it doesn’t.

What the score measures

On eToro, the risk score is a 1–10 summary built primarily around the observed volatility of the portfolio and the risk characteristics of the assets in it. Think of it as a compression: a complex history of portfolio movement compressed into one number that answers roughly one question — how much has this portfolio’s value been swinging?

That’s real information. It’s also all the number can carry. Compression loses detail, and the lost detail is where the interesting risks live.

What the score cannot tell you by itself

To actually understand a trader’s risk, open the portfolio behind the number and inspect:

Leverage. The great multiplier. Leveraged positions turn routine dips into serious hits and introduce an outcome unleveraged investors never face: forced closure at the worst moment. My own book is unleveraged stock — not timidity, but because leverage structurally breaks the “no single trade should matter” rule from Series 1.

Concentration. Ten positions of 10% and one position of 100% can produce similar volatility on a calm week. They are different species. Check the largest position and how much sits in one sector or theme — “diversified across five AI stocks” is one bet wearing five costumes.

Correlation. Twenty positions that all rise and fall together are, for risk purposes, one position.

Turnover and holding period. Fast turnover isn’t automatically bad, but a rapid trader’s edge must survive spreads and slippage on every round trip — and a copier inherits all that friction. Longer hold times, like my typical multi-month positions, tend to transfer more faithfully.

Liquidity. Positions that are easy to enter can be expensive to exit in stress, and stress is exactly when exits happen.

Behaviour under stress. None of the above is static. The question is what happens to all of it inside a drawdown.

Reading changes in the score

A rising risk score during a drawdown is a reason to investigate — not a verdict. Did the market simply become more volatile, or did the trader change position sizing, leverage, or concentration? The number gives you the question. The portfolio gives you the answer.

The habit to build: never accept the summary number without opening the portfolio behind it. The score tells you how much the boat has been rocking. It doesn’t tell you who’s steering, or what they do in a storm — and that’s the part you’re actually copying.
