SanDisk Corp (SNDK) surged 25.99% to $1279.96 in a single session, driven by renewed optimism in the memory chip sector following statements from major tech firms. The rally reflects investor confidence that rising demand for memory chips, particularly in AI applications, will continue to drive pricing higher. Recent comments from Amazon and Apple management highlighted ongoing supply constraints and elevated costs, reinforcing the sector’s potential.
What Happened
The stock’s sharp increase came after Amazon and Apple signaled continued pressure on memory costs, which has historically benefited chipmakers. This followed Microsoft’s earnings report, where the company emphasized its aggressive AI investments while maintaining financial discipline. These developments were interpreted as positive for chipmakers like SanDisk, which had previously been hit by a broader selloff in AI-related stocks. The move also coincided with broader market enthusiasm for the Nasdaq 100 and a strong after-hours performance from Amazon.
Retail and institutional traders appear to be reentering the sector, with retail traders on r/wallstreetbets calling for support of SanDisk and Micron. Meanwhile, SanDisk’s recent insider activity shows a pattern of selling by executives, with no insider purchases in the past 90 days. The stock is set to report Q4 earnings on August 5, which could provide further clarity on its performance.
What The Data Shows
SanDisk’s fundamentals remain strong, with a trailing twelve-month revenue increase of 82.8% and a net margin of 34.2%. The stock has swung dramatically in recent months, trading between $40.10 and $2354.39 over the past 52 weeks. Despite a 18.4% decline in the last eight sessions, the recent 25.99% rebound suggests a potential short-term reversal. Options activity has also been skewed toward calls, with $91.4 million in call premiums compared to $0 in puts, indicating bullish positioning.
What To Watch
The key event on the horizon is SanDisk’s Q4 earnings report on August 5. Investors will be watching for signs of sustained demand and pricing power. In the meantime, coverage breadth is expanding, with 31 stories from 12 sources published in the last 36 hours.
