The reduced liquidity and price decline suggest potential shifts in investor sentiment.

To evaluate the strategy of daily purchasing the 500 most actively traded stocks and holding for one day, precise parameters are required. Key considerations include defining the universe (e.g., Russell 3000 vs. S&P 500), volume measurement (share count vs. dollar value), entry/exit conventions (close-to-close vs. open-to-close), weighting methods, and transaction costs. These decisions directly impact the strategy’s feasibility and returns, necessitating rigorous back-testing to isolate variables and assess risk-adjusted performance.
