Opening Summary
SanDisk Corporation (SNDK), a leading maker of NAND flash memory and storage solutions spun off from Western Digital in early 2025, rebounded sharply in Thursday's session. The stock climbed 4.28%, or $34.51, to $840.94, following a prior close of $806.43. The advance marked a tentative recovery from a punishing selloff that had erased more than a fifth of the company's market value in a single day, as bargain hunters stepped in to buy the dip across the memory and AI-chip complex.
A Bounce After the Post-Midterm Rout
The rally was primarily a recovery move. In the previous session, SNDK plunged roughly 22% as investors dumped crowded AI and memory-stock positions following the U.S. midterm elections. Concerns that a shift in Washington could lead to new restrictions on data-center construction and a slowdown in AI infrastructure spending rippled across the semiconductor sector, dragging peers such as MU lower as well. Thursday's bounce reflected a reassessment that the selloff had become overextended relative to the company's underlying fundamentals.
IREN Results Reassure AI Demand
A key catalyst behind the rebound came from AI-cloud operator IREN, which reported fiscal first-quarter revenue of $228 million, beating estimates near $221 million. Its AI-cloud revenue nearly tripled sequentially to $200 million, and its contracted backlog reached $20.3 billion. The figures signaled that customers are still committing capital to AI computing infrastructure, easing fears that demand for memory and storage chips tied to the AI buildout is about to stall.
Strong Fundamentals Despite the Selloff
The recovery also reflects recognition that SNDK's recent operating results remain exceptionally strong. The company reported fiscal first-quarter revenue of $11.03 billion, up 378% year over year, with adjusted earnings of $49.51 per share. Data-center revenue, the engine of the AI-driven boom, jumped 61% sequentially to $4.8 billion. Management guided fiscal second-quarter revenue to $12.2 billion to $12.6 billion, and the company announced an eight-for-one stock split effective November 19.
Market Context and Trading Activity
Trading activity reflected elevated volatility rather than a fresh fundamental catalyst. The previous session's decline came on volume roughly two to three times the stock's recent average, and Thursday's rebound saw active participation as investors rebalanced positions. The bounce aligned with a broader recovery in memory names and AI-linked chip stocks, with MU and AMD also recovering part of their prior-day losses. Firmer S&P 500 futures and a pullback in oil prices, which eased inflation and interest-rate concerns, lent additional support to risk assets. Technically, SNDK remains well below its 50-day and 200-day moving averages after breaking key support levels during the week's decline.
What Comes Next for SNDK
Investors will be watching whether Thursday's bounce can be sustained or whether it represents a brief reprieve within a broader correction. Key risks include the pace of NAND pricing, competition from China's YMTC as it expands advanced NAND capacity, and the durability of data-center demand amid broader questions about AI infrastructure spending. The company's next quarterly report, expected in late January following the stock split, will offer critical evidence on whether it can sustain pricing power and volume growth through the remainder of the fiscal year.
