Why it's trending
The trigger is SanDisk's third consecutive double-digit percentage drop, with a 14% fall on Tuesday, extending a brutal July that saw the stock lose 54%. This rapid decline has sparked investor panic and search interest in the stock's prospects.
SanDisk shares plunged 14% on Tuesday, marking the third straight session of double-digit percentage losses, according to Seeking Alpha. The slide follows drops of about 11% in the previous two sessions, compounding a devastating July that made SanDisk the S&P 500's worst performer, down 54% for the month, as reported by Barron's.
The selling pressure persists despite management's optimistic narrative. On its last earnings call, SanDisk highlighted a new strategy of multiyear supply partnerships backed by over $11 billion in financial guarantees, aiming to create a 'significantly more predictable and less cyclical business.' Data center revenue surged 233% sequentially as AI infrastructure scales, and the company has paid down debt and authorized a $6 billion buyback. Yet the options market reflects deep uncertainty, pricing a 68% probability that the stock trades between $430 and $3,793 over the next year—a potential 66% drop or 197% gain, as Trefis notes.
The timeline of the crash began in July 2026, when SanDisk shares lost 54% overall, making it the S&P 500's biggest loser. The most recent three sessions—each dropping over 10%—accelerated the decline, with Tuesday's 14% loss extending the rout. The company's long-term supply agreements, while intended to lock in demand, have sparked analyst concerns about capping upside in a market where pricing has been accelerating, and about the sustainability of non-GAAP gross margins that hit 78% last quarter.
The broader implications center on whether SanDisk has truly broken the boom-and-bust cycle of the memory chip industry or merely built a high tower on shifting sand. Investors are watching for signs that the new partnership model can deliver durable profitability, but the current volatility suggests the market remains skeptical. Next, watch for analyst revisions and any further updates on customer commitments or margin trends.
