Short sellers made bold moves this week. Wolfspeed saw the biggest jump. Its SI % of Free Float hit 72.5% — up a massive 20.4 percentage points in just seven days. Availability has hit zero, meaning new short positions are almost impossible to open. The semiconductor firm has struggled with mounting losses and heavy debt.
Carvana is a surprise entrant this week. Its SI % FF leapt from 2.1% to 9.6% — a 7.5pp jump. Bears are growing louder despite the used-car platform's $54bn market cap. Availability remains high at 233%, so shorts can still get in.
Lyft also drew fresh bearish attention. SI % FF climbed to 29.3%, up 5.1pp over the week. The ride-share stock is one of the most actively shorted mid-caps in the US right now.
STAAR Surgical sits at the top of the static most-shorted list at 94% SI % FF. Days to cover stands at 7.2. Analysts remain broadly bearish, with average target prices 24% below current levels.
Lucid Group also saw a 7.5pp rise to SI % FF. EV scepticism continues to dog the stock.
On the macro front, global oil market volatility linked to the Iran conflict is rattling energy-sensitive names. Watch short positions in this space closely.
