A stock that traded at $45 a year ago now changes hands near $1,729. That is a 3,718% gain in twelve months for SanDisk (NASDAQ:SNDK | SNDK Price Prediction), and Axios rounded the headline to roughly 3,700%. Then in the last five sessions before July 2, the stock gave back 17%. Long-term holders have to decide whether that is a breather or the first tell of a cycle top.
The number behind the mania
The SanDisk chart rewires how you think about a boring category. NAND flash was a commodity business the market wanted nothing to do with a year ago.
Now the company carries a market cap of about $256 billion, up from a share price of $41.55 at its Q4 FY25 filing in August. Between then and the Q3 FY26 filing on April 30, 2026, the price ran to $1,095. It kept going after that, printing a 52-week high of $2,354.39 before the recent slide.
The fundamentals came, and then some
Give the bulls their due. Q3 FY26 delivered revenue of $5.95 billion, up 251% year over year, beating consensus by 25.68%. Non-GAAP EPS came in at $23.41 against a $14.66 estimate. Gross margin swung from 22.5% a year earlier to 78.4%. The datacenter segment alone posted $1.47 billion in revenue, up 645% year over year, as AI hyperscalers bid up NAND supply.
Management retired $650 million in debt and now runs a zero long-term-debt balance sheet. Free cash flow hit $2.99 billion in the quarter. CEO David Goeckeler called it “a fundamental inflection point for Sandisk where our technology leadership is enabling a deliberate shift in our mix toward the highest-value end markets, led by Datacenter.” Forward guidance for Q4 FY26 calls for revenue of $7.75 billion to $8.25 billion and non-GAAP EPS of $30.00 to $33.00, plus five signed New Business Model agreements anchoring the datacenter mix.
Why the cycle looks late
Still, memory is memory. When gross margin runs from the low twenties to the high seventies in twelve months, you are late in a boom. The stock proves it. One-year return of ~3,700%, year-to-date 529%, and then a –17% week ending July 2 as buyers ran out.
In late June, r/wallstreetbets threads titled “$SNDK puts for tomorrow” gained traction while another user posted realized gains on 0DTE $2,175 puts. Meanwhile the top r/stocks post going into July asked “Bought SanDisk (SNDK) at $2,330. Did I mess up buying the top or is this just a healthy pullback?” That divergence, professional hedgers reaching for downside protection while retail chases, is the classic late-cycle setup.
Valuation adds weight to the bear case. Trailing P/E sits at 60x, forward P/E at 27x, price-to-sales at 20x, and price-to-book at 19x on a company whose consumer segment already declined 10% sequentially in Q3. Reliance on the Kioxia joint venture, tariff exposure, and NAND pricing volatility are all disclosed risks. Prediction-market fundamentals peg fair value at $1,604.57, implying -11.34% downside, even as sell-side consensus reaches for $1,930.50.
Market reaction
Shares closed at $1,745 on July 2 and traded at $1,807.05 intraday on July 6, 2026, a 3.56% bounce off the recent low.
Over the past month the stock is up just 5%, a stall after months of vertical gains. The 50-day moving average of $1,610.45 now sits well above the 200-day at $703.36, a spread that historically compresses either through time or through price coming down.
Bear case
A one-year run that explosive in a cyclical commodity business demands a reckoning at some point. Memory boom-and-bust is a decades-old rhythm, and the same operating leverage that pushed gross margin to 78.4% works in reverse when NAND prices soften.
Consumer already turned sequentially. Insider transaction data is empty in the reporting window, so the exit signal shows up in options flow and price action rather than filings. A 17% five-day drawdown off a market cap of roughly $156 billion is a warning that the marginal buyer may have left the room.
Bottom line
The next test arrives with Q4 FY26 results, where management guided to revenue of $7.75 billion to $8.25 billion and EPS of $30.00 to $33.00. Anything short of a clean beat, and the multiple has nowhere to hide.
For retirement-focused holders who watched SanDisk turn a flash-memory business into a $268.02 billion AI proxy, the case for trimming into strength is stronger than the case for adding at 60x earnings after a 37-bagger. Cycles end. This one looks tired.
