Seagate closed at $753.25, down 3.80%, after opening at $767.00 and fluctuating between $750.68 and $770.00.

Despite the decline, large options flow leaned bullish. The standout was a $823,600 net-debit, four-leg call spread expiring in October 2026, accompanied by a smaller short put sale. These trades suggest institutional participants positioned for constructive price action rather than a bearish breakdown.

Options Indicators

Seagate’s implied volatility stands at 67.65%, while its IV percentile is just 17.93%, indicating that although the absolute IV level appears high, it is still low relative to its own recent history. In that context, options are currently on the cheaper side rather than richly priced, and the IV/HV ratio of 0.98 suggests implied volatility is broadly in line with realized volatility, reinforcing the view that current option premiums are relatively reasonable. The Call/Put volume ratio is 2.53.

Large Trades

A call spread structure with a net debit of $823,600 was the largest displayed trade, built as a four-leg call combination expiring on 2026-10-30. All strikes in the structure—long 880 calls, short 970 calls, short 980 calls, and long 1100 calls—were out of the money versus the $753.25 reference stock price, making this a defined-risk upside call spread configuration rather than a simple outright bullish call purchase. Because it includes both bought and sold calls, it should be viewed as a spread strategy, and the reported size is the net debit of $823,600. Strategically, this kind of position points to a directional upside view with risk capped by the long wings, suggesting the trader is paying premium for a structured bullish bet while also using the short call legs to reduce upfront cost.

A small bullish single-leg trade also appeared, with a short 540 put expiring on 2026-10-16 worth $10,000. That put strike is out of the money relative to the current stock price, so selling it reflects a moderately bullish to neutral stance: the trader is collecting premium while expressing confidence that STX will stay above 540 into expiration. Taken together, the large-trade flow leans bullish overall. The dominant trade was a net-debit call spread aimed at upside participation, while the put sale added a premium-collection expression consistent with confidence in downside support, indicating that institutional activity was positioned for constructive price action rather than a bearish breakdown.

Strategy Reference

For a low probability of assignment, a premium seller could consider the 540 put expiring 2026-10-16—already used in the large-trade flow—since it sits far below the current price and aligns with the observed downside-support view. If margin efficiency is a concern, replicating the four-leg call spread with defined risk may be preferable to selling naked puts.
