Quarter-End Storm: Insiders Sell, Bears Pile In, Options Expire

Today marks a quarterly options expiry. That alone makes it a volatile session. Three other themes are colliding with it.

Semiconductor Bears Strike Hard

WOLF short interest hit 117% of free float. That is an extraordinary level. Bears added 16.5 percentage points in just seven days. Availability is now zero — there are no shares left to borrow. AI chip newcomer CBRS also drew heavy fire, with short interest climbing to 37.8% of free float, up 6 points on the week. Meanwhile, analysts are pulling ratings on chip names. Micron lost a recommendation today. ON Semiconductor did too. The bearish turn in semiconductors is broad.

Insider Selling Dominates Filings

Executives are cashing out. An NVDA director filed a $186M share sale this week. ASTS CEO Abel Avellan filed a $146.7M sale in AST SpaceMobile after a strong run. AMAT CEO Gary Dickerson filed over $24M in three separate transactions. These are not routine trades. The scale of selling stands out.

Earnings and Expiry Converge

NKE reports tonight. STZ and GIS follow Monday. All three carry notable short interest. NVDA sits at the center of today's expiry, with the largest active options chain on the market. Gamma exposure into the close will be significant.

Europe: Oil and Crypto Slide

Brent crude fell back below pre-Iran-conflict levels as Gulf flows picked up. Bitcoin dropped below $60,000, hitting a 20-month low. Retail investors appear to be rotating from crypto into AI-linked equities. UK budget airline easyJet rejected a £4.9bn takeover approach from Castlelake, though talks are continuing.
