Micron Technology closed at USD 974.33, rising 3.97%.

Despite the positive close, large options flow painted a starkly different picture. A $239.15 million net-debit put combination and a $25.99 million bear put spread dominated activity, while bullish block trades were completely absent. With total bearish premium reaching $504.10 million versus $0.00 million bullish, institutional sentiment was decisively negative and heavily skewed toward downside protection or outright bearish speculation.

Options Indicators

MU’s implied volatility is 69.39%, while its IV percentile stands at 30.68%, which suggests the stock’s current volatility environment is broadly neutral and only slightly above the lower end of its recent range. Combined with an IV/HV ratio of 0.70, options do not appear aggressively priced relative to the stock’s realized volatility, indicating premiums are not especially rich at the moment. The Call/Put volume ratio is 1.35, but this headline reading is misleading given the massive put-side dollar imbalance in block trades.

Large Trades

A net-debit three-leg put combination worth $239.15 million was the standout large trade of the day, structured as long the August 21, 2026 $1,190 puts and $1,200 puts while short the August 21, 2026 $1,140 puts. With a net debit of $239.15 million, this was a sizable downside expression rather than a premium-collection trade, indicating a strongly bearish positioning or a substantial hedge against a deeper decline in MU. All three strikes were already in the money versus the $974.33 reference stock price, which reinforces that the buyer was seeking meaningful intrinsic downside exposure rather than cheap out-of-the-money convexity. The added short $1,140 put leg reduces some cost, but the structure still reflects a large net outlay aimed at capturing further weakness while partially financing the protection.

A bearish put spread with a net debit of $25.99 million was the second highlighted block, built by buying the August 21, 2026 $1,190 put and selling the August 21, 2026 $1,100 put. This is a classic bear put spread, executed for a net debit and designed as a defined-risk bearish trade that profits from continued downside while capping maximum payoff below the short strike. Both strikes were in the money relative to the $974.33 stock reference, so the spread was positioned in a part of the chain with substantial intrinsic value, suggesting a deliberate bearish stance rather than a speculative low-premium lottery ticket. Overall, the bulk-order flow was decisively bearish, with total bullish amount at $0.00 million versus total bearish amount at $504.10 million, leaving a net bearish imbalance of $504.10 million. The absence of meaningful bullish large-trade flow, combined with the dominance of net-debit put structures and bearish spreads concentrated in in-the-money strikes, points to institutional sentiment that is clearly negative and focused on downside exposure or defensive hedging.

Strategy Reference

Given the low IV percentile and bearish institutional tone, a trader seeking to avoid large margin requirements could consider a defined-risk bear put spread using out-of-the-money strikes, such as buying the $900 put and selling the $850 put in the same expiration, to express a smaller directional view with capped risk rather than selling puts outright.
