A $129 million SMH bearish options trade placed just before 11 a.m. ET on Monday upended what had otherwise been the most bullish day for semiconductor sentiment since April, setting up a stark divide between the crowd and a single, anonymous deep-pocketed trader on the Nasdaq PHLX.
The trade involved the purchase of 20,100 contracts on the 630-strike puts in the VanEck Semiconductor ETF (SMH), expiring 20 November, for a total outlay of $129 million. Open interest in that contract stood at fewer than 50 lots at Friday’s close, making this almost certainly a fresh position rather than a roll or an adjustment.
With the fund itself trading around $594, the 630-strike put sits well in the money. Traders and analysts reading the tape interpret a deep in-the-money put of this size, placed in isolation, as a synthetic short: effectively a direct bet that the semiconductor sector falls. According to data from SpotGamma and ThinkOrSwim cited in the original report, the trade was 3.5 times the size of the next-largest transaction on the day, a $37 million leg of a multi-part trade in Sandisk.
The SMH Bearish Options Trade in Detail
The backdrop makes the position all the more pointed. The ratio of open put to call contracts on SMH slid to 1.89 on Monday, the most lopsided towards calls since early April, according to Barchart’s SMH put/call ratio data. As recently as the last week of June, that ratio had reached 3.5, a one-year bearish extreme. It has not fallen below 1.5 in at least a year, reflecting the persistent demand for puts as a hedge against long equity exposure.
The ratio’s journey this year has tracked price closely. Traders began loading up on puts in late May and early June as SMH momentum faded. The ratio hit its one-year bearish peak on 24 June, just two days before the fund topped out and entered a 25% drawdown. The recent collapse back towards calls suggests that hedging pressure has eased considerably.
Zed Francis, chief investment officer of Chicago-based Convexitas, which runs a semiconductor options trading strategy for clients, explained the dynamic: ‘Bank exposure to leveraged ETF and Situational Awareness this summer got to the point they felt very exposed to jump risk in semiconductor names and that caused hedging and volatility to go way up. Now they don’t need those hedges, and I believe unwinding of those hedges has made volatility in the sector inexpensive.’
Inexpensive is an understatement by recent standards. SMH implied volatility collapsed from 65% last month to 40% on Monday, its lowest level since February. Barchart’s SMH quote data puts implied volatility at 40.20%, with an IV Rank of 41.59% and an IV Percentile of 58% at the time of the data snapshot, against a 60-month beta of 1.73 for a fund with roughly $69.49 billion in assets under management. For context, the fund’s all-time implied volatility high was 60.52%, recorded on 20 July 2026.
When Cheap Volatility Invites the Contrarian
It is the cheapness of the options, at least partly, that appears to have attracted the big trade. Don Kaufman, co-founder of TheoTrade, framed the logic bluntly: ‘The further out you go in some of these semiconductor options, the dumber the options pricing gets betting on an upside crash. That unto itself makes me a contrarian.’
Whether the Monday buyer shares that precise reasoning is unknowable. What is clear is that the position is large enough to matter. At $129 million, it accounted for over a third of total premium traded in SMH across the entire session.
The SMH bearish options trade now sits as an open question for the sector. The crowd, as measured by the put/call open interest ratio, has moved decisively towards calls, with put open interest at 1,486,787 contracts against call open interest of 751,623, giving an open interest ratio of 1.98 at the time of the Barchart snapshot. The single contrarian trade cuts against all of that. One of them will be wrong by 20 November.
