Survivorship Bias in Backtesting
Survivorship bias occurs when an analysis only considers the assets or strategies that currently exist, ignoring those that have failed or were delisted. In backtesting a trading strategy for crypto or derivatives, if the model only uses data from currently successful tokens, the results will be significantly skewed toward positive performance.
This gives the trader a false sense of security and leads to an overestimation of the strategy's viability. Many protocols and assets have failed, and excluding them from historical analysis ignores the reality of market risk.
To perform accurate backtesting, one must include the entire history of the asset class, including failed projects, to get a true representation of risk and expected returns.
