Sandisk Corporation (NASDAQ:SNDK) rose 6.28% to $1877.57 in morning trading on September 22, 2026, driven by Rosenblatt Securities initiating coverage with a Buy rating and a $2,400 price target. The analyst cited AI-driven demand for NAND flash and Sandisk’s technological edge in collaboration with Kioxia as key factors. The stock opened at $1770.94 and reached an intraday high of $1902.00 at 9:45 AM ET.

What Happened

Rosenblatt analyst Kevin Cassidy initiated coverage of Sandisk with a Buy rating and a $2,400 price target, emphasizing the growing role of NAND flash in AI infrastructure. This followed a 1.4% pullback earlier in the session before the rating was announced. The stock has gained more than 600% in 2026, with Rosenblatt suggesting it still has room to run.
