Short sellers dramatically increased bets across a handful of micro-cap US stocks in the past seven days. BDRX (Biodexa Pharmaceuticals) saw the biggest move. Its SI % of Free Float exploded from 60% to 681% in a single week. That signals heavy short-selling pressure against a tiny float.
ISPC (iSpecimen) was another standout. SI jumped from just 1.2% to 268% of free float. LRHC (La Rosa Holdings) and XXII (22nd Century Group) also posted triple-digit SI gains week-on-week.
Among larger names, WOLF (Wolfspeed) remains one of the most-shorted mid-caps. SI sits at 51.6% of free float. The semiconductor firm has bounced 109% over three months — a classic squeeze setup, with availability near zero at just 0.8%.
SPRY (ARS Pharmaceuticals) carries and a brutal 25 days-to-cover. Availability is just 10%. Any positive catalyst could force rapid short covering.
TNGX (Tango Therapeutics) hit 56.9% SI after surging 84% over three months. Bears are holding firm — but the cost to borrow remains low at 0.47%, suggesting shorts are not yet being squeezed on financing costs.
On the social media radar, TSLA continues to attract attention. Tesla's SI sits at a modest 2.6% of free float. News flow around the stock remains active, with BYD competition headlines circulating widely today.
Bitcoin ETFs also dominated headlines. IBIT (iShares Bitcoin Trust) pulled in $467 million in ETF inflows as BTC reclaimed the $82,000 level — fuelling bullish sentiment in crypto-adjacent names.
