On July 31, SanDisk Corp. rose 7.79% in regular trading, trading at $1402.46/share, with turnover of $3.601 billion. The stock extended its strong rebound momentum as the broader storage chip sector surged.

On the news front, Microsoft reported earnings that significantly exceeded expectations, triggering its best single-day performance in 18 years and a surge of over 15%. The Philadelphia Semiconductor Index rallied more than 8%, with storage chip stocks leading the advance. SanDisk surged as much as 26% during the session, while Micron gained over 18% and SK Hynix rose over 17%. Additionally, ARM reported quarterly earnings above consensus, with revenue of $1.289 billion versus estimates of $1.26 billion, further catalyzing the semiconductor rebound.

SanDisk had previously declined over 50% from its highs due to concerns over AI demand inflation stemming from Nvidia's circular financing model, as well as competitive pressure from ChangXin Memory's IPO and capacity expansion. The current rally carries characteristics of an oversold bounce. The company is scheduled to report earnings on August 5, with consensus EPS of $33.28.
