Top Performing S&P 500 Stocks for H1 2026

In the first half of 2026, the top three performing stocks in the S&P 500 were Sandisk (NASDAQ: SNDK), Micron (NASDAQ: MU), and Intel (NASDAQ: INTC), with returns of approximately 860%, 304%, and 278%, respectively, by June 30. These impressive gains came despite a weak market on July 1.

The rise in Sandisk and Micron is attributed to a shortage in the memory chip market, driven by increasing demand from artificial intelligence data center build-outs. Micron has projected that the memory chip market will remain tight beyond 2027. Conversely, Intel, which has lagged in the chip foundry sector, recently gained a significant customer in Apple. However, it remains significantly overvalued compared to its competitors.

With high growth projections for Micron at over 200% for the current fiscal year, analysts recommend that it may be the best buy among the three stocks moving forward.
