SanDisk has raised its NAND Flash contract prices by 50% in November to align with supply and demand dynamics, leading to a record high stock price. This move is part of a broader trend in the industry, with companies like Samsung, SK Hynix, and Kioxia also considering price increases. The storage sector is experiencing a surge, with SanDisk up by approximately 4.8% and other key players showing strength. This shift follows a year of stagnant NAND prices close to cost levels.
