Trading strategy success: skill vs. luck depends on statistical test

By PulseAugur Editorial · [1 sources] ·

A study analyzing 399 trading strategies found that determining whether a strategy's success was due to skill or luck depended heavily on the statistical test used. When testing against a synthetic dataset with a real trend, counting all strategies incorrectly dismissed the genuine edge, while considering them as independent bets incorrectly validated strategies with no inherent advantage. The research also highlighted that evaluating the selection process itself, not just the final pick, is crucial, as the gap between in-sample and out-of-sample performance indicates the degree of luck involved.

    I ran 399 trading strategies on the same prices. Whether the winner was luck depended on the question.

    <p>I ran 399 trading strategies on the same price history and asked one question: is the winner skill or luck?</p> <p>The answer depended almost entirely on which test I used. The tests did not disagree because some were wrong. They were answering different questions, and only on…
