SanDisk (NASDAQ:SNDK | SNDK Price Prediction) has become the loudest story in memory. The stock closed at $1,600.62 on Thursday, up 3,505% from a year earlier, when it was still trading around $44.40.
The rally rests on a real business shift. Fiscal fourth-quarter revenue rose to $8.96 billion, up 371.59% year over year, and non-GAAP EPS came in at $39.25 against a $33.28 consensus.
CEO David Goeckeler framed the setup this way on the August call: “Demand from our customers is growing faster than our supply. We therefore expect bids to remain on allocation beyond calendar year 2027.” A well-funded Chinese competitor could shorten that runway.
Why the Rally Still Has Fuel
The core bull case is a locked-in order book. SanDisk signed New Business Models with eight data-center and edge customers, with a weighted-average duration of over four years.
Management put minimum expected revenue from those agreements at $93.9 billion assuming floor pricing, and said NBMs should account for roughly two-thirds of bits in fiscal 2028.
Datacenter grew to 38% of the bit mix as of the end of fiscal 2026, up from about 12% a year earlier. That mix shift is why non-GAAP gross margin reached 84.6%.
Analysts have followed the move. The Alpha Vantage consensus price target is $2,107.70, with 15 buy ratings, 4 holds, and 1 sell.
How YMTC Could End the Party
The threat is capacity. YMTC captured roughly 14% of global NAND shipments in the second quarter and reportedly moved ahead of SanDisk and Micron, a shift that changes the supply math for the whole industry.
NAND is cyclical, and Goeckeler acknowledged as much: “And if you get it wrong, the implications are kind of tragic, right? We saw that in 23.” A determined Chinese entrant, potentially backed by an IPO, could add wafers faster than hyperscaler appetite can absorb them.
SanDisk’s filings list evolving trade policies, tariff regimes and trade wars at the top of its risk stack. Manufacturing is through a joint venture with Kioxia, which adds geopolitical exposure to an already tight supply picture.
Options desks are hedging accordingly. The full-chain put/call ratio is 0.67, but January 2027 sits at 5.87, a lopsided bet on downside protection right where a Chinese supply response would show up.
What to Watch From Here
Retail conviction has wobbled. Reddit sentiment turned bearish on August 19, driven by a wallstreetbets thread asking whether memory volatility signaled a bubble (we wrote a free handbook on riding a mania while planning the exit, here).
The stock is up only 0.71% over the past month, even as the year-to-date gain is 574.29%. That flattening is the market pricing in the tension between contracted demand and future Chinese supply.
The bullish cycle is likely to hold through calendar 2027 because NBM commitments account for more than half of next year’s bits, and hyperscalers cannot swap suppliers on short notice. The setup gets more fragile in 2028, when YMTC capacity additions and any macro softness could meet a market that has already priced perfection.
Investors keeping an eye on the stock should track two signals: YMTC’s IPO filings and NAND spot pricing. Both will tell you when the supercycle narrative starts to crack, well before the earnings do.
