SanDisk shares fell more than 7% on Tuesday to close at $1,617.70. Amid the sharp decline, the options market saw a sizeable put purchase valued at approximately $23.82 million. Based on the increase in open interest, the trade was likely a purchase of 1,854 contracts of the July 17, 2026 $1,750 put.

With the strike price above the underlying share price of $1,744.43 at the time of the transaction, the option was already in the money, suggesting the trade was not a low-cost wager using far out-of-the-money contracts. Instead, the positioning carries stronger downside exposure and hedging characteristics.

Large purchases of deep in-the-money puts are often associated with investors seeking to protect existing long positions or other related exposures against further declines. The trade may also reflect a more outright bearish view that the stock has additional downside potential.

Unusual Options Activity

PDD Holdings showed $1.37 million call purchase, with the transaction concentrated in the September 18, 2026 $90 call. The accompanying increase in open interest suggests the position was likely initiated by a buyer establishing a sizeable long call position.

The contract remains out of the money, indicating a directional bullish bet on the stock's longer-term performance. The buyer appears to be positioning for PDD shares to break above the $90 level, allowing the option's leverage to amplify potential gains.

As a single-leg long call strategy, the trade offers limited downside risk while requiring a meaningful move in the underlying stock to become profitable, reflecting a more offensive positioning rather than a defensive hedge.
