Western Digital Corporation closed at USD 438.34 with a 0.93% gain.
A notable burst of bullish options activity accompanied the move, highlighted by a single $1.05 million put sale. The trade, executed through a deep out-of-the-money strike extending to 2026, signals strong conviction in price stability and a clear preference for premium collection over outright directional bets.

Options Indicators
WDC’s implied volatility is 79.43%, while its IV percentile stands at 47.01%, which places current volatility in a neutral historical range rather than an extreme one. Even though the absolute IV level appears high, the percentile suggests this is fairly typical relative to WDC’s own recent volatility history, so options are not especially cheap or especially expensive at the moment. The IV/HV ratio of 0.73 further indicates implied volatility is running below historical realized volatility, suggesting current option premiums are not stretched. The Call/Put volume ratio is 1.55.
Large Trades
A put sale worth $1.05 million stood out as the key large trade, with 3,920 contracts of the September 18, 2026 $290.00 put sold while the stock reference price was $438.34. This strike sits well out of the money, making the trade a moderately bullish to neutral income-oriented position: the seller is collecting premium while expressing confidence that WDC is unlikely to fall below $290.00 by expiration. Strategically, this type of large OTM put sale often signals either willingness to accumulate shares at a much lower effective level or a view that downside risk is being overpriced. Overall sentiment was clearly bullish, with total bullish large-trade flow at $1.05 million versus bearish flow at $0.00 million, leaving a net bullish difference of $1.05 million. The directional takeaway is decisively positive, and the tone of the flow suggests investors were more interested in premium collection on distant downside strikes than in paying for downside protection, indicating confidence in WDC’s price stability and limited expectation of a severe selloff over the trade horizon.
Strategy Reference
For traders seeking a similar premium-collection setup with lower margin requirements, selling a nearer-term put spread—such as a monthly 0.15-delta put spread—may offer a controlled risk profile while still capitalizing on WDC’s neutral-to-bullish IV structure.
