Memory Stocks Slide on Report Apple May Source Chinese Chips: SanDisk Down 9%, Micron and Western Digital Down 7%

SanDisk dropped 9% and Micron fell 7% after reports the Trump administration may let Apple source memory from Chinese suppliers ahead of Xi's U.S. visit.

KC Rajkumar calls the selloff an overreaction, noting that CXMT can't qualify for Apple iPhones and YMTC has committed its newest NAND to domestic customers.

Memory stocks are sliding Monday morning after weekend reports that Washington may permit Apple ( NASDAQ:AAPL ) to source memory chips from Chinese suppliers. The policy shift would land squarely on the U.S. and Korean players that dominate the group.

SanDisk ( NASDAQ:SNDK ) stock is down 9% to $1,458.29, leading the group lower. Meanwhile, Micron Technology ( NASDAQ:MU ) stock is down 7% to $897.86 in early Monday trading, the cleanest read-through to any shift in Apple's DRAM sourcing.

Western Digital ( NASDAQ:WDC ) stock is down 7% to $429.49 on similar sector-wide pressure, and SK Hynix ( NASDAQ:SKHY ) stock is down 5% to $154.48 as the selling spans geographies. The Roundhill Memory ETF ( CBOE:DRAM ) is down 7% to $53.62, matching the individual names almost exactly and signaling that traders aren't sorting between NAND and DRAM exposure.

The uniformity is the tell. This looks like a policy-headline shock landing on a sector that had already run enormously, with SanDisk stock up 572% year to date through Friday's close and Micron Technology stock up 239% YTD through Friday's close. Gains like that invite exactly this kind of gap risk (we wrote a free handbook on riding a mania and planning the exit here: The Bubble Survivor's Handbook).

Weekend Report on Chinese Memory Sourcing

Reports circulating over the weekend said the Trump administration may permit Apple to source DRAM from China's CXMT and NAND flash memory from YMTC. The move is described as a possible diplomatic gesture ahead of President Xi Jinping's planned U.S. visit, expected on or around September 24. Apple has said it is "evaluating all options" on memory supply and that Chinese sourcing "could help us on the supply side and perhaps the pricing side."

The stakes concentrate at Micron. As the dominant U.S. supplier of the high-density lpDDR5x DRAM Apple uses in iPhones and Macs, Micron Technology shares carry the most direct read-through to any shift in Apple's memory sourcing decision.
