Large options activity showed a $16.50 million double short put spread aimed at premium collection and a $10.81 million long put combination signaling a bearish hedge. While the largest trade sold far out-of-the-money puts to harvest time decay, the second-largest trade paid a net debit for downside puts, reflecting a defensive tilt in institutional positioning.

Options Indicators

SPDR S&P 500 ETF Trust currently has an implied volatility of 15.90%, with an IV percentile of 20.72%, indicating volatility is on the low side and options are cheaply priced relative to their own recent range. The IV/HV ratio of 1.55 suggests implied volatility still sits above realized volatility, so while absolute option pricing is not high, the market is still embedding a moderate premium over recent actual movement. The Call/Put volume ratio is 1.02.

Large Trades

A premium-collection put spread package worth $16.50 million was the largest displayed trade, structured as a same-direction double short put combination expiring on November 30, 2026. The trader sold 75,000 out-of-the-money 675.0 puts and 75,000 out-of-the-money 570.0 puts with SPY referenced at 774.83, taking in a net credit of $16.50 million. This is a short put spread-style income trade built to collect premium from time decay and stable price action, signaling a neutral-to-bearish stance in the sense that the trader is not chasing upside and is willing to be exposed if SPY weakens materially, though both strikes sit well below spot and therefore imply confidence that any downside will remain contained.

A directional put-buying package worth a net debit of $10.81 million was the second highlighted trade, consisting of long 12,500 November 20, 2026 736.0 puts and long 12,500 November 20, 2026 733.0 puts. Both legs were purchased out of the money against the 774.83 reference price, making this a same-direction double long put combination aimed at capturing a sizable downside move or a volatility expansion rather than harvesting premium. Because the position pays premium upfront and concentrates on lower strikes below spot, it reads as an explicit bearish hedge or speculative downside bet, with the buyer positioning for a meaningful drop in SPY into that expiration window.

Overall, the large-trade flow leans bearish. The displayed headline orders were dominated by put structures, and while the biggest trade sold downside premium far below the market in a range-bound income expression, the second-largest trade was an outright net-premium put purchase that points to concern about a larger downside move. Combined with the broader bulk-order imbalance favoring bearish exposure, the tape suggests institutions are more focused on downside protection and negative directional setups than on sustained upside participation.

Strategy Reference

For sellers seeking a low assignment probability with defined risk, the short 570.0/675.0 put spread expiring November 30, 2026 mirrors the largest trade, while those unwilling to post wide margin could instead sell a single 570.0 put and pair it with a long 500.0 put to cap downside exposure.
