Short sellers turned aggressive in the final week of August. Data as of August 31 shows some of the sharpest seven-day moves seen this summer.
HighPeak Energy HPK led all large movers. Its short interest jumped 8.4 percentage points in a single week. It now sits at 43% of free float. The timing tracks the broader oil market nervousness flagged by headlines. Bears are also piling into crude oil ETFs — the Brent Oil Fund BNO saw utilization hit 93.9%, near its 52-week high, with available borrow tightening sharply.
SpaceX SPCX saw SI climb 6.75 points to 23.6% of free float. Klaviyo KVYO was another notable riser, jumping from 13.2% to 20% in seven days. Both names are seeing fresh bearish conviction from institutional desks.
On the persistently shorted side, Wolfspeed WOLF remains at 72% of FF with zero shares available to borrow. That's a powder keg. 1-800-Flowers FLWS sits at nearly 74% FF short with 29 days to cover.
Capricor Therapeutics CAPR added 8.2 points week-on-week to 45.2% of FF. It has been trending higher all month.
Bears are clearly rotating into energy and small-cap tech. Watch WOLF closely — zero availability with that level of short interest rarely stays quiet.
