Memory chip maker Sandisk (NASDAQ: SNDK) was the best-performing stock in the S&P 500 (SNPINDEX: ^GSPC) in 2025, and it’s currently leading the index higher in 2026. The stock has advanced 570% year to date amid a severe memory chip supply shortage fueled by the artificial intelligence infrastructure build-out.

In general, analysts think Sandisk remains undervalued. Wall Street’s median target price of $2,500 per share implies 57% upside from its current share price of $1,590. But I think the stock will increase 91% to $3,040 per share by August 2027 (i.e., when the company reports financial results for the full fiscal year).
