SanDisk Corp. (SNDK) shares surged 5.10% during Wednesday's intraday trading, leading a broad rally in memory and semiconductor stocks.
The movement appears driven by multiple factors. Firstly, the broader U.S. stock market gained strength as both the U.S. and Iran signaled a potential end to the conflict in the Middle East, reducing geopolitical risk premiums and boosting investor confidence across sectors. Additionally, this represents a technical rebound following a sharp 10% plunge in the previous session, which was triggered by market concerns over Google's TurboQuant algorithm that aims to improve memory efficiency for AI models.
Analyst commentary suggests the previous sell-off in memory stocks may have been an overreaction. Research indicates that storage companies became undervalued by approximately 20% following the TurboQuant announcement. Bernstein upgraded Western Digital and stated that fears surrounding the algorithm's impact were overdone, benefiting the entire memory sector including SanDisk. The stock also showed pre-market momentum as chip stocks gained ahead of the regular session.
