Bullish positioning in the VanEck Semiconductor ETF (SMH) strengthened Monday as the ratio of open put to call contracts fell to 1.89, its most call-leaning level since early April, according to Barchart. At the same time, the biggest single options trade across the market was a bearish $129 million purchase of 20,100 deep in-the-money SMH put options expiring Nov. 20, a move that data from SpotGamma and ThinkOrSwim suggests was likely a new synthetic short position. The split highlights a familiar market dilemma in semiconductors: follow improving broad sentiment or side with a large contrarian wager as option costs fall. SMH implied volatility (market pricing for expected swings) dropped from 65% last month to 40% Monday, its lowest since February, making protection and directional bets cheaper. Traders had previously built up puts in late May and early June as SMH momentum slowed, with the put-call ratio reaching a one-year bearish high on June 24, two days before the fund peaked and then fell into a 25% drawdown.
