Short Sellers Eye Liquidia, Energy, and Grindr

Short interest jumped sharply in several mid-cap names in the five days to 28 October, with bears picking new targets across pharma, energy, and social media.

LQDA saw the biggest move among names with meaningful market caps. Short interest rose 7.8 percentage points to 26.8% of free float. The $4.1bn pulmonary hypertension drug maker has been a contested name, and the fresh short build adds pressure ahead of any pipeline news.

TLN attracted attention from a different angle. Short interest in the $16.7bn power generator doubled in five sessions, jumping 5.2 points to 10.7% of free float. Energy sector volatility is running hot, and data center power demand is a live debate.

GRND added 5.4 points to reach 20.5% of float. The social dating platform has drawn short sellers even as its stock trades near recent highs.

On the high-short-score leaderboard, EVCM stands out with an ORTEX short score of 97. Its cost to borrow hit 78%, and availability has effectively vanished at under 1% of outstanding short interest.

WOLF remains a heavy short. The semiconductor name carries 88% of float shorted, with zero availability and rising days to cover.

Meanwhile, CCO cost to borrow surged 136% in a week per ORTEX data, hitting 1.30% as short interest climbed to a one-year high. The iShares Russell 1000 Growth ETF IWF also saw short interest spike 38% in a week, signalling broad hedging activity against growth stocks.
