Short interest data as of September 24 shows a dramatic week for bearish positioning. The biggest mover is BRVE (Braveheart Bio). Its SI % of FF exploded to 585.6%, up from 226.5% just seven days earlier — a 359-point jump that is extraordinary even by small-cap standards.
Among larger names, SPCX (Space Exploration Technologies) drew fresh attention. SI % of FF rose to 30.6% from 20.7% over the same period. Shorts are building, even as bulls debate the stock on social platforms.
GME is back on the radar. Short interest jumped from just 0.9% to 7.5% of FF in one week. That's a rapid rebuild of bearish positioning in one of the most watched meme stocks on the market.
NKE also caught short sellers' eye. SI % of FF climbed to 8.1%, up from 6.2% last week. Sentiment around the brand remains weak heading into autumn.
On the other side, shorts covered hard in MRNA. SI fell nearly 2 points to 8.1%. CHWY saw covering too — SI dipped from 74.1% to 67.2%, though it remains one of the most heavily shorted names in the market.
In gene editing, NTLA shorts are holding firm at 34.1% even as options traders turn bullish. That standoff could signal a squeeze if positive catalysts emerge.
MMED (MiniMed Group) saw SI jump from 38.5% to 68.3% in a week — a 30-point surge worth watching closely.
