SanDisk shares rose approximately 7% during Friday trading after the company reported a 372% year-over-year revenue increase in the fourth quarter and announced a $14 billion stock repurchase authorization. The results exceeded analyst expectations and pointed to a recovery in NAND flash memory demand, particularly among artificial-intelligence datacenter customers. The stock had gained more than 6% in the previous session and outperformed as the S&P 500 fell 0.2% and the Nasdaq declined 0.1%. Semiconductor sentiment was also supported by Nvidia CEO Jensen Huang’s forecast that chip revenue in 2027 would be twice the expected 2026 level. A pullback in Treasury yields and crude oil prices after the Federal Reserve raised its target interest-rate range by 25 basis points to 3.75%-4.00% on September 16 further supported growth-oriented technology shares. Analyst consensus remained Buy, with an average 12-month price target of about $2,124. Chief Executive David Goeckeler sold approximately $51.7 million of shares on September 14 through a prearranged Rule 10b5-1 trading program, while Chief Financial Officer Luis Visoso sold about $1.57 million on September 15 through a comparable arrangement. The plans were established several months earlier and are generally viewed as portfolio diversification rather than a signal about SanDisk’s future performance. SanDisk has gained approximately 580% year to date, giving it a market capitalization of roughly $222.6 billion, while average daily volume is about 13.7 million shares. Its focus on datacenter solutions and advanced flash-memory technology has made it a major participant in AI infrastructure investment, and current technical indicators rate SNDK as Strong Buy.
