PRISM Mid-Day Movers: Healthcare and Biotech are leading Todays Index’s.

Shares of Bullfrog AI Holdings, Inc. (NASDAQ: BFRG) are surging again, recently up about 60% as traders continue to pile into the ultra‑low‑float AI‑driven drug‑development name following its new commercial partnership with a large pharmaceutical company. The sharp move extends an already explosive rally and underscores how a small absolute increase in buying interest can drive outsized percentage gains in a sub‑scale, loss‑making micro‑cap, leaving the stock squarely in momentum‑driven, high‑risk territory where reversals can be just as violent as the upside.

Shares of Polaryx Therapeutics, Inc. (NASDAQ: PLYX) are trading higher, up about 19%, as speculative money moves back into this ultra‑early‑stage rare‑disease biotech. The thin float and low absolute market cap mean even modest incremental buying can translate into outsized percentage gains, keeping the stock firmly in high‑volatility territory where sentiment and positioning often matter more than near‑term fundamentals. 

Other Notable Movers:

Modular Medical (MODD) up 19%

Knightscope (KSCP) up 18%

IO Biotech (IOBT) down -74%
