Sandisk Corp ended Monday down 2.4% at $583.35, after bouncing between $553.32 and $605.92 throughout the day. Volume came in at about 14.7 million shares.
Sandisk shares are losing steam after a steep rally that made the stock a favorite for traders betting on AI data-center growth and changing memory prices. Despite the pullback, it’s holding onto a gain of about 152% for 2026.
Stocks managed to steady themselves, but worries about interest rates haven’t gone anywhere. “You’ve a sharply oversold market where a little bit of good news can go a long way,” said Keith Lerner, chief investment officer at Truist Advisory Services. Traders are eyeing upcoming U.S. economic numbers for hints about what the Federal Reserve might do next. Reuters
Micron Technology slid 2.8% in the storage-and-memory group, while Western Digital managed a 1.3% gain by the close.
Sandisk, which sells NAND flash—the kind of non-volatile memory packed into solid-state drives—set off a rally in late January after forecasting fiscal third-quarter revenue with a midpoint of $4.6 billion and adjusted earnings at $14 per share. Both figures came in ahead of Wall Street estimates, Reuters reported. CEO David Goeckeler told Reuters AI is now boosting flash storage demand, even though DRAM, the faster memory positioned closer to the processor, is still the most constrained part of the supply chain.
Sandisk posted earnings that Morgan Stanley described as “above the long-term trend.” The analysts see that run continuing “for more than one year” if AI growth sticks around. Reuters also reports Sandisk and Japan’s Kioxia have extended their flash-chip supply pact out to 2034. Reuters
After parting ways with Western Digital, the company made its solo Nasdaq debut in February 2025. Shares are listed as “SNDK,” it says. Sandisk
Traders dumped positions Monday, not because of fresh fundamental news, but that didn’t stop markets from whipping around all session. Volatility was hard to miss.
Even so, that narrative about shortages driving the rally can reverse abruptly. Should supply begin catching up—or if any signs emerge that cloud budgets are slowing—high-flying expectations might take a hit in a hurry.
Market focus shifts to the U.S. Employment Situation report dropping Feb. 11 at 8:30 a.m. ET, while the Consumer Price Index lands two days after, same hour. Either print could jolt yields—potentially pushing around high-volatility names like Sandisk.
