SanDisk Stock Plunges 12% Amid Rising Chinese NAND Competition Fears

Key Facts

1SanDisk stock fell 12% on Monday, marking a decline of more than 45% from its June peak.

2The stock broke below its 100-day moving average amid intensifying fears over Chinese NAND competition.

Amid intensifying pressure on the global semiconductor sector, SanDisk stock experienced a sharp sell-off, plunging 12% on Monday. This decline extends the stock's downward trajectory to more than 45% below its record high recorded in June. According to reports, the move reflects growing investor anxiety over intensified competition from Chinese NAND flash memory manufacturers, which threatens to disrupt established market dynamics.

Technically, the stock broke below its 100-day moving average for the first time since August 2025, signaling a significant shift in momentum. This breakdown followed reports that the Shanghai IPO of ChangXin Memory Technologies has renewed fears regarding Beijing's expansion into the memory chip market and its potential impact on industry pricing. Per market data, SNDK closed at $1,436.56 on July 24, 2026, after hitting a session low of $1,411.50.

Investors are now watching whether the stock can stabilize after losing nearly half its value in recent weeks. While the upcoming economic calendar shows no direct semiconductor earnings, market participants will be looking at broader trade data from Japan and China in late July to gauge the health of the global electronics supply chain and competitive pricing pressures.
