Negative options flow is piling into semiconductor and clean energy names this week, while macro concerns dominate the broader tape.
NVDA, MU, and AMD top the US market for bearish options bets over the past seven days. That comes as JPMorgan Chase CEO Jamie Dimon warned publicly of rising inflation and rate risks, a backdrop that tends to accelerate put buying in high-multiple tech.
Clean energy ETF ICLN is flashing a sharper signal. Short interest jumped 34% in a single week to 3.5% of float. Cost to borrow sits at 3.44%. Colorado battery-electric vehicle registrations rose for a fourth straight month in July 2026, per Atlas EV Hub data, but that momentum has not slowed the bears on the ETF.
Moderna carries its own weight here. Short interest stands at 9.4% of free float. ORTEX Index Rebalance Radar puts MSCI World addition probability at 90%, which would force roughly $4.8 billion of buying into a stock with significant put exposure.
Flutter Entertainment adds an index twist. MSCI World deletion probability jumped to 86% overnight. That puts $589 million of forced selling in play. Short interest is already 12% of free float.
Uber saw a key robotaxi executive depart, per Bloomberg. Availability of shares to borrow sits above 7,000%, meaning the market is not crowded short, but the news flow could attract fresh put buyers.
