From Record $1,861 to a 12% Rout: What Tripped SanDisk's Run

SanDisk fell 11% on Broadcom guidance miss and rate hike fears; strong fundamentals and $42B long-term contracts sustain bullish view.

SanDisk’s roller-coaster week ended with a thud that seemed to come from nowhere — except that the entire semiconductor ecosystem was already wobbling. The stock crashed 11.39% on Friday alone, closing at $1,559.32 and wiping out a chunk of the gains that had pushed it to an all-time high of $1,861 just four days earlier.

The sell-off had two distinct triggers, one global and one company-specific. The broader market took its cue from Broadcom, which on June 4 projected third-quarter AI chip revenue of $16 billion — roughly $1.2 billion short of analyst expectations. Broadcom refrained from raising its full-year AI semiconductor guidance, and its shares plummeted 14% in a single session. The contagion swept through the supply chain: SanDisk lost more than 6% that day, and by Friday both SanDisk and rival Micron had each surrendered about 12%.

Friday’s rout was supercharged by an unexpectedly hot US jobs report. The Bureau of Labor Statistics reported 172,000 new positions created in May, more than double the 80,000 forecast. Strong hiring data raises the probability of further Federal Reserve rate hikes, a prospect that hits high-growth technology names hardest. The double blow of a sector sentiment shift and macroeconomic tightening left SanDisk’s holders scrambling.

Technical analysts spotted trouble brewing before the weekend. The stock’s MACD indicator formed a death cross, a bearish signal that often precedes additional downside. SanDisk also slipped below its short-term moving averages, and on June 5 unusual activity in the options market emerged: put volume surged dramatically, far exceeding prior interest. The 50-day moving average near $1,180 now looms as a critical support zone.

Adding to the unease, two insiders cashed out just before and during the sell-off. Chief Technology Officer Alper Ilkbahar sold 2,000 shares on June 1 for roughly $3.5 million. Two days later, the company’s chief legal officer disposed of 600 shares at $1,736 under a prearranged trading plan. Insider sales — especially when clustered near a peak — rarely inspire confidence, even if legally compliant.

The fundamental backdrop, however, remains a stark contrast to the stock’s recent volatility. CEO David Goeckeler has spent years weaning SanDisk off the volatile NAND spot market, pivoting to long-term supply agreements with enterprise and hyperscaler customers. In the third quarter of fiscal 2026 alone, the company signed three such contracts with minimum revenue commitments of approximately $42 billion. Financial guarantees exceed $11 billion, and $400 million of that has already been received as prepayments. The model protects against the wild margin swings of the spot market, where gross margins can oscillate between 78% and below 20% in a single year.

SanDisk’s balance sheet is debt-free, with a current ratio of 4.8 and free cash flow near $3 billion. Analysts remain overwhelmingly bullish: of 22 tracked by S&P Global, 32 rate the stock a buy, four say hold, and none recommend selling. Morgan Stanley raised its price target to $1,750 from $1,100 earlier this month, and the average three-month target stands at $1,717 — still well above the current price.

Yet the valuation debate is fierce. By certain earnings-based models, the stock appears nearly 490% overvalued. The tension between a compelling growth narrative and a pricing that leaves zero room for error is the central fault line. Rumors about changes in memory configurations have also swirled, adding an extra layer of uncertainty to an already nervous market.

SanDisk remains up roughly 467% year to date — a gain that dwarfs any single week’s loss. The 52-week low of $146 from October 2025 feels like ancient history. But when a stock has rallied that far that fast, any misstep — a sector-wide wobble, a hot jobs number, or an insider sale — can trigger a disproportionate correction. The fourth-quarter earnings report will be the next real test of whether the contract-based model can deliver on its promise, especially as demand for AI-optimized solid-state drives faces growing scrutiny.
