Tape Overview

PRF Technologies Ltd. (PRFX) is gapping up 227.8% on 22M shares, leading all gainers despite a lack of fresh fundamental catalysts. This move follows a period of consolidation and appears driven by momentum traders targeting low-float structures.

Top Loser: HOTH — [Massive volume spike on downward gap]

Hoth Therapeutics, Inc. (HOTH) is plunging -33.8% on a staggering 135M shares, representing over 365x its average volume. The aggressive sell-off signals a major liquidity event or institutional exit following recent volatility.
