Molina Healthcare Surges 1.42% Amid 34.23% Drop in Volume Ranks 491st in U.S. Trading Activity

On September 26, 2025, Molina Healthcare (MOH) closed with a 1.42% gain, trading at a volume of $210 million, a 34.23% drop from the previous day's activity. The stock ranked 491st in trading volume among U.S. equities. Despite the decline in trading activity, the modest price increase suggests limited short-term volatility amid broader market dynamics.

Recent developments indicate renewed focus on Medicaid expansion in key states, which could impact Molina's membership growth trajectory. Analysts note that regulatory shifts in enrollment caps and premium rate adjustments remain critical variables for the company's near-term performance. The stock's muted volume suggests reduced speculative positioning following recent earnings reports.

To execute the back-test, clarification is required on the investment universe parameters. Will the analysis include all U.S.-listed common stocks or focus on specific indices like the S&P 500? Transaction cost assumptions also need confirmation—should the test assume zero trading costs, or incorporate realistic per-trade expenses? Once these details are finalized, the volume data will be processed to generate daily top-500 lists, with the back-test running from January 1, 2022, through the current date.
