Key Points

Shares of the iShares Semiconductor ETF (NASDAQ: SOXX) surged by 112.8% in the first half of 2026, fueled by significant investments in the semiconductor sector amid an AI infrastructure boom, particularly driven by rising memory chip stocks.

As of July 10, 2026, the ETF has increased nearly 300% over the last five years. Major contributors to this growth include Micron Technology, whose stock rose 314% year-to-date due to a memory chip shortage, and Intel, which is capitalizing on the demand for CPUs in AI applications. The market cap of semiconductor companies is prominently represented among the world’s largest, with many directly linked to AI technologies.

Despite these gains, analysts caution against further investments in the semiconductor sector for the remainder of 2026 due to its historical cyclical nature, suggesting that the current bull market may soon face downturns.
