Short sellers have been busy this week. Wolfspeed tops the movers list with SI % FF jumping to 47% — up 7.5 percentage points in just seven days. The chip maker's ongoing financial struggles continue to attract bears.
Scholastic Corporation saw an even sharper relative move. SI % FF leapt from 13% to 21.6% in a week — a gain of 8.5 points. That's the biggest weekly jump among mid-cap US stocks.
Avis Budget Group remains one of the most heavily shorted large-caps. SI sits at 74% of free float. Shares available to borrow are almost gone — availability is just 0.1% of short interest. A catalyst here could ignite a violent short squeeze.
Vail Resorts is another newcomer to the bear watchlist. SI jumped 5.5 points to 21.9% this week.
In the news, Sportradar stabilized after a Muddy Waters short report rattled the stock. ORTEX data shows SI at with ample availability at 508%. Bears have room to add.
