Sandisk Corp (NASDAQ: SNDK) shares fell 5.90% to $1488.44 on Monday, driven by growing concerns regarding Chinese competition in the memory sector. The decline occurred as broader weakness hit memory peers, including Micron and SK Hynix, following reports of significant progress by China’s CXMT on chip structures.

What Happened

Memory stocks faced pressure in premarket trading on Monday, with Micron down approximately 2.1% and SK Hynix also lower. The sell-off was attributed to reports that China’s CXMT unveiled key progress on a chip structure previously pursued by major industry players like Samsung and SK Hynix. This development intensified fears of increased competition in the NAND flash market. Sandisk’s earnings report is scheduled for October 29, a date analysts view as a critical test for the company’s ability to stabilize NAND cash flow amid shifting price dynamics.

What The Data Shows

The stock opened at $1558.40, a 1.5% gap down from the prior close of $1581.82. It hit a session high of $1558.79 at 7:00 AM ET before sliding to a low of $1485.25 at 9:40 AM ET. Volume stood at 0.9 million shares, which is 0.1 times the three-month daily average. The company has a market capitalization of $231.6 billion and a P/E ratio of 21.4. Trailing twelve-month revenue increased 175.3%, with a net margin of 56.5%. The 52-week range is $116.17 to $2354.39. Over the last eight sessions, the stock declined 8.1% from $1742.37 to $1600.53. On October 12, the stock printed eight fresh 52-week lows. Recent insider activity includes nine sells totaling $104,000 over the last 90 days, with no buys. CEO David Goeckeler sold shares on September 17, and CFO Luis Felipe Visoso sold on September 15.

What To Watch

Investors will monitor the October 29 earnings report for signs of stabilizing NAND prices and cash flow. Analysts from Mizuho, Rosenblatt, and Arete Research have recently raised price targets, citing surging AI data center demand. The upcoming report will serve as the next major test for the stock after its significant rally in 2026.
