New York, February 12, 2026, 10:11 EST — The session is now underway.
- Sandisk shares jumped 10.3%, hitting $661.18 in early trading
- Seagate, Western Digital, and Micron all rose, following the surge in storage stocks
- New HBM4 shipments and buzz about tighter supply have pushed memory pricing back into the spotlight
Shares of Sandisk Corp surged 10.3% to $661.18 early Thursday, climbing as high as $666.80 during the session as investors renewed interest in the memory-and-storage sector.
This shift highlights how the market continues to focus on memory supply as the immediate driver, powered largely by AI infrastructure demand. It’s important since memory price fluctuations can quickly impact profit margins.
Sandisk wasn’t the only one on the rise. Seagate Technology jumped 11.2%, Western Digital climbed 8.2%, and Micron Technology edged up 4.6%, lifting the whole group in tandem.
Samsung Electronics sparked some action in Asia by announcing it has started shipping its new HBM4 high-bandwidth memory chips to customers. HBM, a high-end type of DRAM used in AI accelerators, remains in tight supply—something traders are watching closely.
The supply crunch is hitting demand too. Lenovo, the world’s largest PC manufacturer, flagged that rising memory costs are weighing on its PC shipments and confirmed it has increased prices to offset the pressure.
Just a day earlier, SMIC CEO Zhao Haijun told the Wall Street Journal the industry is “panicked” over memory supply, with firms aggressively overbooking components. According to the report, memory prices have surged 80%-90% since late 2025. Zhao also mentioned that more supply might arrive in roughly nine months. The Wall Street Journal
Micron gained momentum in the U.S. after CFO Mark Murphy revealed at a Wolfe Research conference that their next-gen HBM4 is already being produced in high volumes and shipped out. Morgan Stanley’s Joseph Moore expects Micron to surpass revenue forecasts thanks to rising prices for DRAM and NAND, the flash memory behind storage devices.
Since spinning off from Western Digital in February 2025, Sandisk has stuck to the same story around demand and pricing. The company posted fiscal Q2 revenue of $3.03 billion and a non-GAAP profit of $6.20 per share. It’s guiding Q3 revenue between $4.4 billion and $4.8 billion, with non-GAAP earnings expected to hit $12 to $14 per share. CEO David Goeckeler highlighted the quarter’s strength, pointing to a “better product mix” and faster enterprise SSD adoption. Sandisk
The setup isn’t one-sided. Memory cycles often trigger swings in both capacity and demand, and rising component costs can ultimately squeeze end-market volumes when device makers hold back.
Investors are now eyeing Friday’s U.S. consumer price index report for January, set to drop Feb. 13 at 8:30 a.m. ET. This report could shake up rate expectations and tech sector risk appetite. As for Sandisk, traders want to see if memory prices hold steady heading into spring.
