The strategy of buying the top 500 stocks by daily trading volume and holding them for one day from 2022 to now delivered moderate returns. The 1-day return was 0.98%, with a total return of 31.52% over 365 days. The strategy's Sharpe ratio was 0.79, indicating good risk-adjusted returns. However, the maximum drawdown of -29.16% highlights its vulnerability during market downturns.
