Soleno Therapeutics stock slides today: SLNO drops on investor-alert headline as biotech sector slips
NEW YORK, December 30, 2025, 2:16 PM ET — Regular session Shares of Soleno Therapeutics, Inc. fell 3.1% to $46.09 in afternoon trading on Tuesday, after a law firm said it was investigating potential claims on behalf of investors. The drop outpaced declines in biotech benchmarks, with the SPDR S&P Biotech ETF down about 1.4% and the iShares Nasdaq Biotechnology ETF off about 1.1%. The move matters because Soleno is still in the early innings of commercializing its first marketed drug, and the stock has traded with sharp swings as investors debate demand, safety perception and pricing power.
