CVS (CVS) closed August 25, 2025, with a 0.13% decline, while its trading volume dropped 33.6% to $0.33 billion, ranking 268th in market activity. The stock’s muted performance followed a federal court ruling imposing a $290 million penalty on

Caremark for alleged Medicare Part D pricing misreporting.

The penalty, stemming from a False Claims Act whistleblower lawsuit, underscores regulatory scrutiny over pharmacy benefit managers’ role in drug pricing transparency. Analysts note the ruling could pressure PBM margins and influence ongoing bipartisan legislative efforts to reform drug pricing mechanisms. CVS has announced plans to appeal the decision, which may prolong legal uncertainties but signals confidence in its compliance processes.

A backtest of a strategy buying the top 500 stocks by daily trading volume and holding them for one day showed a total profit of $2,940 from December 2021 to August 2025, with a maximum drawdown of -$1,960. The strategy’s Sharpe ratio of 1.53 indicates strong risk-adjusted returns, though it recorded a $790 loss in August 2025, the worst-performing month in the period.
