Short sellers have been busy this week. The biggest movers are mostly micro-caps — but a few familiar names are worth watching.
Biodexa Pharma Surges to the Top
BDRX (Biodexa Pharmaceuticals) saw the most dramatic short interest jump of the week. SI % of Free Float exploded from 100.7% to a staggering 2,301% — a sign of extreme share dilution and heavy bearish positioning. This is a high-risk micro-cap.
Meme Stocks Creep Higher
GME short interest ticked up to 15.1% of free float, from 13.7% a week ago. AMC rose to 16.5%, up from 15.7%. Bears are rebuilding positions in both names.
Rumble Carries the Highest Short Score
RUM holds the top short score among larger stocks at 94.2. Its 19-day DTC and near-zero availability make a squeeze technically possible. SI actually dipped slightly this week to 25.2%.
Biotech Bear Target: SPRY
SPRY (ARS Pharmaceuticals) has 63.7% of its float shorted and just 3.2% availability. Days to cover sits at 25 — one of the highest in the market.
AAOI Trends Overnight
AAOI (Applied Optoelectronics) is trending on social platforms today. Its SI climbed to 14.3% from 13.6%. Worth monitoring given the buzz.
