SanDisk Stock Plummets Amid Semiconductor Sector Sell-Off
SanDisk shares dropped up to 35% following Samsung Electronics' Q2 earnings, triggering a broader decline across the semiconductor and memory industry.
Shares of SanDisk experienced a significant sell-off on July 7, 2026, with the stock dropping 9.8% during morning trading and falling as much as 35% from its recent all-time high. The decline occurred alongside a broader downturn in the semiconductor and memory sectors, affecting other industry players including Micron Technology, SK Hynix, and Kioxia.
The volatility followed the Q2 2026 earnings report from Samsung Electronics. Despite Samsung reporting an operating profit surge to $58.4 billion and a 28% sequential increase in sales, its own shares fell 7%. Investors reacted to a "buy the rumor, sell the news" scenario, as much of the growth had already been priced into the market.
Market pressure intensified after Samsung announced the construction of massive semiconductor fabrication plants. Investors viewed the expansion as a potential increase in market supply, contributing to the sector-wide decline. Micron Technology also saw its share price pare back gains despite reporting quarterly revenue of $40 billion.
