iShares Semiconductor ETF

iShares Semiconductor ETF (SOXX) is a BlackRock-managed exchange-traded fund offering targeted exposure to US-listed companies across the semiconductor value chain. It is one of the most widely held semiconductor-sector ETFs, used by investors seeking direct access to chip design, manufacturing, and equipment companies that underpin AI infrastructure and modern computing.

What does iShares Semiconductor ETF track? 

SOXX tracks the ICE Semiconductor Sector Index, which measures the performance of US-listed equities classified within the semiconductor sector according to the ICE Uniform Sector Classification schema. The fund generally invests at least 80% of its assets in the index's component securities and economically similar instruments, with the index rebalanced quarterly.

What does iShares Semiconductor ETF hold?

The portfolio is concentrated almost entirely in semiconductors and semiconductor equipment and materials, spanning companies involved in chip design, fabrication, memory production, and the specialised manufacturing equipment used across the chip-making process. A smaller portion of assets is allocated to international companies listed on US exchanges, giving the fund modest geographic diversification within an otherwise concentrated sector exposure.

iShares Semiconductor ETF Investment strategy

SOXX follows a passive, index-tracking strategy designed to replicate the holdings and weightings of the ICE Semiconductor Sector Index as closely as possible, generally holding around 30 of the largest US-listed semiconductor companies. Because the underlying index is itself concentrated by design, the fund's strategy results in meaningful single-stock weight at the top of the portfolio, making it most suitable for investors seeking a focused bet on the broader semiconductor industry rather than diversified technology exposure.
