Short sellers stepped up pressure across several names this week. The data through April 27 shows clear intent.
WOLF saw the sharpest jump among larger names. Short interest hit 48.2% of free float, up from 39.7% just seven days ago. That's an 8.5 percentage point rise in a week. The silicon carbide chipmaker has faced persistent margin pressure, and bears are adding to already-heavy positions. Availability sits at just 2.0% — shares to borrow are almost gone.
CAR (Avis Budget Group) carries a massive 74.3% SI % FF — one of the highest among billion-dollar companies. Cost to borrow is 4.4%. The stock is up 68% in three months, yet shorts refuse to back down.
RUM (Rumble) is a social media favourite with a 131% cost to borrow. Availability is nearly zero at 0.02%. Short score is 93 — the highest among mid-cap names. With days-to-cover at 23.6, any positive catalyst could spark a violent squeeze.
Oil above $110 and Iran war fears are dominating headlines. Defence and energy shorts face headwinds. Short sellers in commodity-exposed names should tread carefully this week.
