What's the Best-Performing S&P 500 Stock in 2025?

Sandisk (SNDK) is the best-performing S&P 500 stock in 2025, with shares up 570% since its February IPO at $38.50, now trading around $250. The memory and storage device manufacturer benefited from a global chip shortage driven by AI and consumer electronics demand, posting strong Q1 results with 21% revenue growth to $2.3B and earnings more than double analyst expectations.
