Sandisk Shares Fall 20 Percent Amid Broader Semiconductor Sell-Off
Sandisk shares dropped roughly 20 percent over the past month, reversing a prior 490 percent surge in 2026. The decline aligns with a wider semiconductor sector correction spanning July 24 to 28, which erased $1.3 trillion across 20 major chip stocks. Analysts attribute the downturn to investor profit-taking, potential cooling in artificial intelligence infrastructure spending, and expected resolutions to memory shortages.
Key points
- Sandisk, a major memory and storage chip manufacturer, saw its share price decline by approximately 20 percent over the past month after rising more than 490 percent earlier in 2026.
- A broader semiconductor market sell-off occurred between July 24 and 28, causing 20 of the world's most valuable chip companies to lose $1.3 trillion in combined market value.
- Nvidia, a leading artificial intelligence chipmaker, contributed significantly to the losses by shedding $238 billion in market value during the same period, according to FactSet and CNBC data.
- Market observers suggest the downturn stems from investor profit-taking, shifting evaluations of artificial intelligence infrastructure spending efficiency, and concerns over future memory and storage supply bottlenecks clearing up.
Sandisk experienced a sharp reversal over the past month, with its stock tumbling roughly 20 percent following an extraordinary 490 percent rally earlier in 2026. This downward movement reflects broader turbulence across the global semiconductor industry rather than company-specific failures alone.
Between July 24 and 28, a severe sector-wide sell-off wiped out $1.3 trillion in market value across 20 of the world's most valuable chip corporations, according to FactSet data reported by CNBC. Nvidia, a central player in the artificial intelligence hardware market, alone accounted for $238 billion of the erased value.
Analysts point to several potential catalysts driving the market correction. Questions have emerged regarding the long-term sustainability of massive artificial intelligence infrastructure investments, particularly as newer models outside China achieve higher performance at reduced costs. Additionally, investors are weighing the risk that current memory and storage shortages could resolve within the next few years, potentially returning cyclical chipmakers to more volatile business models once artificial intelligence tailwinds subside. Profit-taking by investors seeking to lock in earlier gains also likely contributed to the recent dip.
