Catalyst Pharmaceuticals stock drops 3% today as CPRX lags biotech in thin year-end trade
NEW YORK, December 30, 2025, 2:30 PM ET — Regular session Shares of Catalyst Pharmaceuticals, Inc. fell 3.0% to $23.33 in afternoon trading on Tuesday. The stock has traded between $23.30 and $24.10 so far in the session. The drop matters because trading can get choppy in the final days of the year, when fewer investors are active and price moves can be exaggerated. Mid-cap healthcare names often swing more than the major indexes in that setting. Catalyst fell 1.2% on Monday to close at $24.06, according to MarketWatch data, and it remains well below its June 9 52-week high
