Two massive trades just happened in Micron and Nvidia. What they could mean for chips

Options trading activity in semiconductors is drawing attention, particularly in Micron and Nvidia, as bearish positioning appears to build. By midday, more than 180,000 put contracts traded in the SMH ETF versus 50,000 calls, with $46 million in premium tied to puts compared with $26 million in calls, according to ThinkOrSwim and SpotGamma data. The put/call open-interest ratio rose to 1.95, the highest since the second week of August. In Nvidia, shortly after the open, traders bought 100,000 180-strike puts expiring Jan. 15 for $21 million—its biggest options trade of the day. Micron shares were around $1,030, and the article notes deep-in-the-money put activity that could function like a synthetic short position.
