Micron closed at $1,045.56, down 1.73% from the prior close.

Large options trades showed a decisively bearish tilt, led by a $3.68 million in-the-money put purchase at the 1050 strike expiring in October 2026. Despite a Call/Put volume ratio of 1.71, the delta-weighted flow and premium deployment favored downside protection. With implied volatility near its 52-week low, the size of this put buy stands out as institutional conviction rather than speculative hedging against an expensive premium backdrop.

Options Indicators

Micron’s implied volatility is 48.60%, and with an IV percentile of just 0.40%, current volatility is sitting at the very low end of its recent range, indicating options are cheaply priced rather than expensive. The IV/HV ratio of 1.05 suggests implied volatility is only slightly above historical volatility, which points to option premiums being broadly in line with realized movement rather than showing a major volatility premium. The Call/Put volume ratio is 1.71.

Large Trades

A PUT buy worth $3.68 million was the standout large trade, with 1,672 contracts bought at the 1050.0 strike expiring on 2026-10-16. With MU referenced at 1045.56, this put was in the money at the time of the trade, which makes the positioning more immediately sensitive to downside risk. The structure is a straightforward bearish put purchase, indicating the buyer was paying premium for downside exposure or portfolio protection, and the deep size suggests a meaningful conviction that MU could remain under pressure or that downside hedging demand is elevated.

Overall, the bulk-order flow was clearly bearish. The dominant signal came from aggressive put buying, while the smaller additional orders also leaned negative rather than offsetting that downside view. Even though one put-selling combination pointed more to premium collection in a range-bound scenario, the broader character of the large-trade activity still reflected a market tone focused on downside risk, defensive positioning, and limited evidence of bullish conviction.

Strategy Reference

For traders looking to fade the bearish extreme without taking on undefined risk, selling an out-of-the-money put spread—such as the 850/800 put spread expiring in 2026—can collect premium while keeping assignment probability low, given that the 850 strike sits well below current support and the IV percentile remains depressed.
