The iShares Semiconductor ETF (SOXX) closed at $568.64 on September 30, 2026, $576.33 on October 1 and $501.93 on October 19, 2026, according to DataPorium price data [1]. That left SOXX up 66.7% for 2026 but 23.4% below its June 22 closing high of $655.01. The VanEck Semiconductor ETF (SMH) closed at $548.46 on October 19, up 52.3% for the year [1]. Neither fund split its shares in 2026: the split records in DataPorium's data show SOXX's last split as 3-for-1 on March 7, 2024 and SMH's as 2-for-1 on May 5, 2023 [1].
Did SOXX or SMH split in 2026?
No. DataPorium's price data list one split for each fund, and both happened before 2026 [1]:
- SOXX: a 3-for-1 split on March 7, 2024. Each share became three, and the price per share fell to about a third, with no change in the value of a holding.
- SMH: a 2-for-1 split on May 5, 2023.
The split list for both funds has no entry dated 2026 through October 19, 2026 [1]. A split changes the share count and the quoted price, not the fund's holdings or returns. Prices quoted in this article are actual closing prices after those splits.

October has been a weak month. SOXX rose to $589.51 on October 5, then fell 16.3% to $493.39 on October 16, before a partial rebound on October 19 [1]. SMH fell 14.8% over the same stretch, from $633.90 to $539.79 [1]. On October 1, SOXX traded between $564.04 and $579.98 on volume of 6.1 million shares; on October 19, volume was 9.3 million [1].
How did semiconductor ETFs move in 2026?
The year has had three distinct phases. In the first, both funds fell into late March: SOXX closed at its 2026 low of $309.79 on March 30, and SMH at $362.53, roughly where they ended 2025 [1]. In the second, SOXX more than doubled to its $655.01 high on June 22, and SMH rose to $668.91 the same day [1].
The third phase has been a long correction with sharp swings. By July 29, SOXX had fallen 29.0% from its high to $465.00, and SMH 24.6% to $504.22 [1]. The largest one-day drop in the past 12 months came on June 5, 2026, when SOXX fell 10.4% and SMH 9.2% [1]. The funds then recovered through September before the October decline.
Over a longer period, SOXX's record shows both the reward and the risk. As of June 30, 2026, the fund had returned 169.60% over one year at net asset value, 56.92% a year over three years and 36.59% a year over ten years, but it lost 35.03% in calendar 2022 [2].
Our analysis of DataPorium's ETF price data shows SOXX's daily moves had an annualized volatility of 46.2% in the 12 months to October 19, 2026, against 39.8% for SMH, and SOXX's 29.0% summer drawdown was deeper than SMH's 24.6%.
How concentrated are SOXX and SMH?
Both funds hold a small number of stocks. SOXX held 30 stocks as of June 30, 2026, split 75.59% into semiconductor makers and 23.97% into semiconductor equipment companies [2]. The SMH index takes the largest 50 U.S.-listed semiconductor stocks by market value and keeps the top 25 by free-float market capitalization and three-month trading volume [4]. Both are non-diversified funds under the Investment Company Act of 1940, which lets them put a larger share of assets into one issuer [4].

How the largest holdings have moved
The top holdings explain most of the fund moves. DataPorium's stock price data show very different paths in 2026 [3]:
| Stock | Close, Sep 30, 2026 | Close, Oct 19, 2026 | Change in 2026 | Change since Sep 30 |
|---|---|---|---|---|
| Micron (MU) | $1,065.11 | $904.90 | +217.1% | -15.0% |
| Advanced Micro Devices (AMD) | $611.76 | $538.05 | +151.2% | -12.0% |
| Taiwan Semiconductor (TSM) | $456.19 | $420.22 | +38.3% | -7.9% |
| Nvidia (NVDA) | $228.38 | $217.09 | +16.4% | -4.9% |
| Broadcom (AVGO) | $351.19 | $334.59 | -3.3% | -4.7% |

Memory and processor makers did most of the work. Micron more than tripled in 2026, while Broadcom was slightly down and Nvidia rose 16.4% [3]. Intel (INTC) fell 23.5% from $120.23 on September 30 to $92.03 on October 19, the steepest drop of the large holdings in October [3]. The rally was not a one-company story, and neither is the October pullback.
Is SOXX overvalued?
On the issuer's figures, SOXX was expensive in mid-2026. As of June 30, 2026, it traded at 76.39 times trailing earnings and 13.23 times book value, with a three-year beta of 2.00 and a three-year standard deviation of 35.47% [2]. Its 30-day SEC yield was 0.01%, so almost none of the return comes from income [2].
Prices have fallen since then. SOXX closed 21.7% below its June 30 level on October 19, 2026 [1]. DataPorium's industry data put the average price-to-earnings ratio of Nasdaq-listed semiconductor companies at 64.3 on June 30, 2026 and 44.0 on October 19, 2026, against 53.9 and 44.4 for the Nasdaq technology sector on the same dates [3]. By that measure, the gap between chip stocks and the wider technology sector has closed, although the fund's own multiple at current prices is not published in this data.
A high multiple is not a forecast of decline, and a lower one is not a floor. Semiconductor earnings are cyclical. A beta of 2.00 means a 10% market move has historically mapped to about a 20% move in the fund [2], and the 29.0% drop between June 22 and July 29, 2026 shows how fast that can happen [1].
How do SMH and SOXX differ in cost and structure?
- Expense ratio. SOXX charged 0.34% as of its June 30, 2026 fact sheet [2]; SMH charges a 0.35% management fee with no other expenses [4].
- Index. SOXX tracks the NYSE Semiconductor Index [5]; SMH tracks the MVIS US Listed Semiconductor 25 Index [4].
- Size. SOXX held $47.8 billion in net assets as of June 30, 2026, with 30 holdings and quarterly distributions [2]. SMH paid one distribution in the 12 months to October 19, 2026, $1.105 per share on December 22, 2025 [1].
- Foreign exposure. SMH's prospectus lists foreign securities risk and Taiwan-specific risk among its principal risks, because it holds depositary receipts of non-U.S. companies such as TSM [4].
