Chips, Shorts, and Spreadsheets: Sunday Roundup

Semiconductors in the Crossfire

Memory chips dominate today's options market — but no one agrees on direction. Micron Technology and Sandisk Corporation are drawing heavy two-sided bets. Sandisk is up 411% year-to-date. Micron has gained 207%. That scale of gains naturally invites both bulls locking in profits and bears positioning for a reversal. NVIDIA and Advanced Micro Devices show the same split. Options flow is elevated on both sides with no clear winner yet.

Short Sellers Stay Busy

Bears are building positions fast. RingCentral saw short interest climb 2.9 points in seven days to 15.1% of free float. Five9 added 2.6 points to reach 14.1%. Hertz Global Holdings remains the most extreme case at 66% of float short. Zero shares are available to borrow. The stock is down 62% in three months. SoundHound AI sits at 43% short with zero availability — a potential squeeze candidate if sentiment shifts.

Aerospace Divides Analysts

Analysts are split on aerospace. Howmet Aerospace and TransDigm Group each received target price upgrades today. Both carry zero sell ratings. Honeywell Aerospace went the other way. Analysts cut its target to $225.31. Six sell ratings now sit alongside just 10 holds — a sharp contrast to its sector peers.

Europe: Insiders and Springer

London's NEXT plc generated the biggest insider headline. CEO Simon Wolfson sold over $42M of shares across two days. In Europe's markets, Springer Nature surged 9% after a strong earnings beat — a rare bright spot on an otherwise quiet Sunday session.

Week Ahead

Super Micro Computer reports Tuesday after the close. AI server demand and margin trends will be closely watched. Cisco Systems follows on Wednesday. Both names sit at the centre of the AI infrastructure trade.
