The absence of earnings reports, partnership announcements, or clinical-stage developments left the price action largely attributable to broader market sentiment.

To build a comprehensive back-test of a strategy involving the top 500 stocks by daily trading volume, key parameters must be defined: the market universe (e.g., U.S. equities, S&P 500, or global indices), weighting methodology (equal-weight or volume-proportional), rebalancing frequency (daily or periodic), and transaction cost assumptions. Benchmark comparisons, such as against SPY, and risk metrics like annualized return and maximum drawdown, would further refine the analysis. Once these parameters are confirmed, a data-driven evaluation can be executed to assess the strategy’s viability from January 1, 2022, to the present.
