SanDisk (NASDAQ:SNDK | SNDK Price Prediction) is staging one of the most fundamentally backed momentum runs in large-cap tech. Shares up 5,283% from their one-year low to their one-year high. But since then, the stock has corrected and finds itself down nearly 47% from its all-time high on June 25.
Up nearly 353% year to date through Aug. 11, dwarfing the 13.19% gain on the S&P 500 and the 17.78% advance on the NASDAQ-100. This is an AI-storage cycle finding its purest public-market expression, and the data says the trajectory will continue.
The Catalyst: A Quarter That Rewired the Story
The company’s Q4 2026 earnings report on Aug. 5 was the inflection. SanDisk reported EPS of $39.25 versus the $33.28. Revenue hit $8.97 billion, up 371.6% year over year. Non-GAAP gross margin was 84.6%.
SanDisk now has eight new business model agreements covering more than 50% of fiscal 2027 bits and approximately two-thirds of fiscal 2028 bits, with a weighted average duration exceeding four years. Signed agreements represent at least $93.9 billion of expected revenue and include $16.5 billion of financial guarantees.
The Forward Driver: Guidance Already Validates the Run
Management now expects FY2027 Q1 revenue of $10.3 billion to $10.8 billion and EPS of $44 to $46. The macro backs it. On the earnings call, CEO David Goeckeler noted that “We delivered record revenue, gross margin, and earnings per share, each above the high end of our guidance, and repurchased $4.5 billion of company stock.” Management said it expects to execute the buyback program consistently, supported by confidence in future cash generation.
The Structural Edge: Supply Tightness Through 2028
NAND is undersupplied, and supply growth cannot catch demand growth. Industry supply is tracking ~17% in 2026 against unconstrained demand in the mid-20s. The shortage is expected to persist until 2028. Combine that with a forward P/E of 24, zero long-term debt, an authorized buyback, and analyst consensus of 14 Buy and 2 Strong Buy ratings with an average target of $1,460.41, and the setup is unusually clean for a stock that has already run.
The Risk, and Why Momentum Is Bigger
NAND is cyclical. SanDisk relies on its Kioxia manufacturing relationship, and hyperscaler customer concentration is real. The consumer segment declined 10% sequentially in Q3. But cyclicality matters when supply is loose. With multi-year volume-and-price commitments locking in datacenter revenue, BiCS8 expected to reach the majority of bit production exiting FY2026, and fabs running at 100% utilization, the cycle is structurally tighter than any previous NAND upturn.
The Signal
SanDisk has the earnings, the guide, the balance sheet, and the contract architecture to keep this trajectory intact. With shares around $1,263.83 as of Aug. 11 and the 50-day moving average at $938.77, the trend is unmistakable. The momentum here is the fundamentals catching up to a market the company is already winning, and it will continue as long as AI infrastructure spending holds its pace.
