The stock has since appreciated to $1121.09, trading near its 52-week high of $1131.24, and has gained 13.9% over the trailing 90 days. Notably, Stahl's prior 5 open-market sales at REGN (all on 2024-02-07) posted subsequent 30-day and 90-day gains ranging from +1.7% to +2.4%, with a 0% well-timed rate at the 90-day mark—meaning the stock rose materially after each prior sale.
