It is a passive ETF managed by VanEck that tracks the MVIS Global Semiconductor 25 Index. It holds a concentrated, market-cap-weighted portfolio of leading global companies across the semiconductor value chain, including AI, memory, and foundry.

It suits thematic investors who want concentrated exposure to the semiconductor value chain, including AI, memory, and foundry, as well as long-term investors who want to add a separate semiconductor allocation within their asset mix.

It is an ETF run by VanEck using a passive (index-tracking) management approach.

The fund holds a concentrated, market-cap-weighted portfolio of the major semiconductor companies included in the MVIS Global Semiconductor 25 Index. Because the weights of its top holdings are very large, the AI, memory, and foundry cycles tend to drive short-term performance. Alongside U.S. names, it also includes some global semiconductor companies from Taiwan, South Korea, the Netherlands, and elsewhere.

• Concentrated exposure to 25 global semiconductor companies
• Direct tracking of the AI, memory, and foundry value chain
• VanEck's flagship semiconductor theme ETF

Assets under management (AUM) stand at $71.9B, and the expense ratio is 0.35% per year.

The SHLD, IHAK, FDTX, CHPX, and BCTK shown in the table are defense, cybersecurity, AI semiconductor, and technology theme variants with different exposure structures. Compared with SOXX (iShares Semiconductor ETF), which targets the same semiconductor theme, the fund differs in its global semiconductor weighting and holdings weights.

During periods of strong AI, memory, and foundry momentum, the fund posted markedly larger gains than core ETFs, while during semiconductor cycle slowdowns its volatility expanded sharply.

It belongs to the group of mega-theme ETFs that see sharp fund inflows when AI, memory, and foundry momentum is strong. Demand from investors adding a separate semiconductor allocation within their asset mix also contributes to inflows.

Its main strengths are concentrated global semiconductor exposure and direct tracking of the AI value chain. Single-theme volatility, top-holding concentration, and currency exposure should be considered in advance.

A direct substitute among semiconductor theme ETFs is iShares SOXX, which tracks a different index and has a different holdings weight composition. The SHLD, IHAK, FDTX, CHPX, and BCTK shown in the table are defense, cybersecurity, AI semiconductor, and technology theme variants with different exposure structures. If you want broad technology and growth exposure, you can also consider QQQ and QQQM, and for a concentrated IT sector position, variants such as XLK and VGT.

Here is a summary of points to review before investing in SMH. Concentrated global semiconductor exposure and tracking of the AI value chain are its strengths, but it is recommended to double-check theme concentration volatility, top-holding concentration, and currency effects before buying, and to review your position size and diversification strategy at the same time.

Theme concentration volatility, top-holding concentration, and exchange rate fluctuations are the main drivers of short-term volatility. During semiconductor cycle slowdowns, drawdowns can be much larger than those of core ETFs, so it is worth reviewing your position size and diversification strategy together.

For direct exposure to the semiconductor value chain, SMH is regarded as the standard choice. If you want concentrated U.S. semiconductor exposure, SOXX is a suitable variant; for broad IT sector exposure, XLK and VGT; and for broad technology and growth exposure, QQQ and QQQM.
