SanDisk shares rose approximately 7% during Friday trading after the company reported a 372% year-over-year fourth-quarter revenue increase and authorized a $14 billion stock repurchase program. The results exceeded analyst expectations and indicated a recovery in NAND flash demand, particularly from artificial-intelligence datacenter customers, clarifying the catalyst behind an earlier 6% advance that had initially lacked a company-specific explanation. SanDisk had gained more than 6% in the previous session, while 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 2027 chip revenue would be twice the expected 2026 level. The Federal Reserve’s 25-basis-point rate increase on September 16, to a target range of 3.75%-4.00%, was followed by declines in Treasury yields and crude oil prices, supporting growth-oriented technology shares. Analyst consensus remained Buy, although reported average price targets varied from approximately $2,124 to $2,282.69. Chief Executive David Goeckeler sold approximately $51.7 million of shares on September 14 and Chief Financial Officer Luis Visoso sold about $1.57 million on September 15 through prearranged Rule 10b5-1 plans. SanDisk had gained approximately 580% to 621.7% year to date in separate market snapshots, with an indicated market capitalization of roughly $222.6 billion.
