What Is SOXX ETF? iShares Semiconductor

SOXX is the ticker symbol for the iShares Semiconductor ETF, a passively managed exchange-traded fund (ETF) issued by BlackRock that tracks the ICE Semiconductor Index. The fund holds approximately 30 U.S.-listed semiconductor and semiconductor equipment companies and trades on NASDAQ. Launched on July 10, 2001, SOXX carries an annual expense ratio of 0.35% and pays quarterly dividends.

An exchange-traded fund (ETF) is a fund that holds a basket of securities and trades on a stock exchange like an individual stock. SOXX gives investors exposure to approximately 30 chip companies in a single purchase, with shares tradeable intraday on NASDAQ at prices near the fund's net asset value (NAV), the per-share value of its underlying holdings. ETFs are generally more tax-efficient than mutual funds because the in-kind creation and redemption mechanism minimizes capital gains distributions.

iShares is BlackRock's ETF brand. BlackRock is the world's largest asset manager with over $10 trillion in assets under management (AUM), and iShares is the world's largest ETF provider with over 1,300 funds globally. SOXX was among the early iShares ETFs, giving it a 20-plus-year track record that few semiconductor-focused funds can match. That scale translates into practical benefits: deep liquidity, tight bid-ask spreads, and institutional-grade fund management infrastructure.

What Does SOXX ETF Invest In?

SOXX invests exclusively in U.S.-listed companies in the semiconductors and semiconductor equipment industry, classified under the Information Technology sector (GICS classification: Semiconductors and Semiconductor Equipment sub-sector). This is a pure-play sector fund, not a broad technology ETF. SOXX does not hold software companies, internet platforms, or consumer electronics assemblers.

Semiconductors, commonly called chips, are the electronic components that power virtually every modern device, from smartphones and laptops to data center servers and AI systems. The fund's holdings span three distinct sub-segments of the chip industry:

• Fabless chip designers: Companies that design chips but outsource manufacturing to foundries. Examples within SOXX include NVIDIA Corporation (NVDA), Advanced Micro Devices (AMD), and Qualcomm (QCOM).
• Integrated device manufacturers (IDMs): Companies that both design and manufacture their own chips. Intel (INTC) and Texas Instruments (TXN) fall into this category.
• Semiconductor equipment makers: Companies that build the machines used to fabricate chips rather than making chips themselves. Applied Materials (AMAT), Lam Research (LRCX), and KLA Corporation (KLAC) represent this sub-segment within SOXX's portfolio.

Chip demand flows from AI infrastructure buildout, consumer electronics, automotive electrification, and cloud computing. The semiconductor industry follows boom and bust inventory cycles tied to capital expenditure and demand shifts, which is one reason SOXX tends to carry higher volatility than broadly diversified index funds.

How SOXX ETF Works: Index Tracking and Portfolio Construction

SOXX works by passively tracking the ICE Semiconductor Index, buying and holding the approximately 30 chip stocks in that index at their specified weights without active stock selection. Fund managers do not decide which stocks to own. The index determines the composition, and SOXX replicates it.

What Does SOXX ETF Track?

SOXX tracks the ICE Semiconductor Index (formerly the PHLX Semiconductor Sector Index, known by its ticker SOX). SOX is an index, not a tradeable ETF. When SOXX launched in 2001, it tracked the Philadelphia Stock Exchange's SOX index. That benchmark transitioned to ICE Data Indices management, becoming the ICE Semiconductor Index. Investors who encounter references to the "SOX index" in older articles are reading about SOXX's predecessor benchmark.

The ICE Semiconductor Index holds approximately 30 U.S.-listed companies in the semiconductor and semiconductor equipment industry. Each company must meet minimum market capitalization and liquidity thresholds for inclusion. The index rebalances quarterly to restore target weights as stock prices shift during the quarter.

How Modified Equal-Weighting Works

The portfolio construction methodology sets SOXX apart from most competitor funds. The ICE Semiconductor Index uses modified equal-weighting: each individual holding is capped at approximately 8% of the total portfolio. Think of it as a playlist where no single song can take up more than 8% of the runtime. Every major chip company gets meaningful representation, not just the biggest one.

This matters because without a cap, a single company's market capitalization could dominate the portfolio. NVIDIA's market cap is many multiples larger than smaller semiconductor holdings, but NVIDIA cannot exceed approximately 8% of SOXX's portfolio regardless of how large it grows. This limits single-stock concentration risk considerably.

Compare this to market-cap weighting, the methodology used by SMH (VanEck Semiconductor ETF). In a market-cap-weighted index, the largest company by market value receives the largest allocation. In today's semiconductor market, that means NVIDIA can represent 20-25% of SMH's portfolio. Modified equal-weighting is like a pie chart where each slice is kept roughly the same size regardless of how popular any one ingredient is. Market-cap weighting gives the most popular ingredient a much bigger slice.

SOXX shares trade intraday on NASDAQ at market prices near the fund's NAV. Most major brokerages offer commission-free ETF trading on SOXX.

SOXX ETF Top Holdings

SOXX ETF holds approximately 30 semiconductor and semiconductor equipment companies, making it one of the more concentrated sector ETFs by number of holdings compared to, for example, the 500 stocks in an S&P 500 fund.

SOXX's top holdings include NVIDIA (NVDA), Broadcom (AVGO), Advanced Micro Devices (AMD), Qualcomm (QCOM), and Intel (INTC) among the top five, with each position capped at approximately 8% of the portfolio. The table below shows the approximate top-10 holdings.

NVIDIA Corporation (NVDA) typically occupies the largest or near-largest position in SOXX, subject to the modified equal-weight cap. NVIDIA designs graphics processing units (GPUs) that have become the dominant hardware platform for AI model training and inference. Because NVIDIA's weighting is capped at approximately 8%, its price movements still influence SOXX directionally, but the impact is meaningfully reduced compared to a fund where NVIDIA might represent 20% or more of the portfolio. Investors seeking diversified AI infrastructure exposure without concentrating in a single stock often turn to SOXX, which pairs NVIDIA with AMD, Broadcom, and other AI-adjacent chip companies across the semiconductor supply chain.

Is SOXX a Good ETF for AI Exposure?

SOXX provides diversified AI chip hardware exposure through multiple holdings, not a single AI bet. The buildout of AI data centers by hyperscale cloud providers including AWS, Google Cloud, Microsoft Azure, and Meta has driven significant demand for GPUs, custom AI accelerators, high-bandwidth memory (HBM), and networking chips since 2023. SOXX's AI-relevant positions include NVIDIA for GPU computing, AMD for competing AI accelerators, Broadcom for custom AI chips built for hyperscale cloud customers, Micron for HBM used inside AI accelerator chips, and Taiwan Semiconductor Manufacturing Company (TSMC, TSM) as the foundry that manufactures chips for NVIDIA and AMD. SOXX is a semiconductor ETF, not an AI ETF. It includes holdings that are not directly AI-related. If AI capital spending growth decelerates, multiple SOXX holdings would face simultaneous valuation pressure.

SOXX ETF Performance and Historical Returns

SOXX has historically delivered annualized total returns that outpaced the S&P 500 during bull semiconductor market cycles, though its higher beta means drawdowns during corrections can be meaningfully more severe than those of a diversified index fund. Beta is a measure of a fund's price sensitivity relative to the broader market; SOXX's beta has historically run above 1.5 relative to the S&P 500 (source: ETF.com SOXX profile and Morningstar SOXX rating), indicating the fund amplifies both gains and losses.

How Has SOXX Performed Over 10 Years?

SOXX has historically generated strong long-term annualized total returns relative to the S&P 500 over 10-year periods, reflecting the semiconductor sector's structural demand growth. Those returns came alongside meaningfully higher volatility, including a drawdown exceeding 35% in 2022. Retrieve current annualized return figures directly from the iShares SOXX ETF fund page, as performance data changes daily.

This table is structured for editorial population at publication time from the iShares SOXX ETF fund page. Add "Data as of [Month DD, YYYY]" when figures are inserted. Past performance does not guarantee future results.

SOXX's 20-plus-year track record spans multiple semiconductor cycles. The dot-com bust (2001-2002) and the 2008 financial crisis each produced severe drawdowns in the fund's early decades. A 2018 trade-dispute correction and a COVID crash followed by a sharp recovery in 2020 illustrated the sector's tendency to fall faster and recover faster than the broader market. The 2022 bear market brought SOXX's steepest recent drawdown, exceeding 35% peak to trough, as inventory corrections and rate hikes compressed semiconductor valuations. The AI-driven rally beginning in 2023 reversed much of that decline as demand for AI chips drove earnings growth across multiple SOXX holdings. Investors considering SOXX should calibrate their expectations to this full historical range, not just recent performance.

Past performance does not guarantee future results.

SOXX ETF Expense Ratio and Costs

SOXX ETF has an annual expense ratio of 0.35%, meaning investors pay $3.50 per year for every $1,000 invested, or approximately $35 per year on a $10,000 position. This fee is also called the management fee in fund prospectus language; both terms refer to the same annual cost.

The expense ratio is deducted daily from the fund's NAV as an accrual. Investors do not receive a separate bill. In context against the semiconductor ETF peer group:

• SOXQ (Invesco PHLX Semiconductor ETF): approximately 0.19% per year, or about $19 annually per $10,000
• SMH (VanEck Semiconductor ETF): approximately 0.35% per year, matching SOXX's cost
• Average sector ETF: approximately 0.40% per year

SOXX sits in the middle of this range, cheaper than the average sector ETF but more expensive than SOXQ. The 0.16 percentage point difference between SOXX and SOXQ compounds meaningfully over a 10-year holding period. Beyond the expense ratio, most major brokerages offer commission-free ETF trading, so transaction costs for retail investors are typically zero.

SOXX ETF Dividend and Income

SOXX ETF pays quarterly dividends, with a typical annual yield between approximately 0.5% and 1.0%. The yield is modest by income ETF standards. Semiconductor companies are growth-oriented businesses that tend to reinvest earnings into R&D and capital expenditure rather than distributing them to shareholders, and that payout behavior flows through to SOXX's distribution profile.

SOXX is primarily a capital appreciation vehicle, not an income fund. Investors who need their ETF holdings to generate substantial current income will find the yield insufficient for that purpose. Dividend distributions are taxable in the year received. For current yield data and distribution history, visit the iShares SOXX ETF fund page.

SOXX vs. SMH vs. SOXQ: How the Major Semiconductor ETFs Compare

SOXX and SMH are different funds from different issuers tracking different indexes with different portfolio construction methodologies. The three primary semiconductor ETFs available to U.S. investors each take a distinct approach to the same sector.

Data as of publication date. Sources: iShares SOXX ETF fund page; VanEck SMH fund page; Invesco SOXQ fund page. Verify current data before investing.

Is SOXX the Same as SMH?

No. SOXX is issued by iShares (BlackRock) and uses modified equal-weighting; SMH is issued by VanEck and uses market-cap weighting, resulting in heavier concentration in the largest semiconductor companies. Their underlying indexes differ: SOXX tracks the ICE Semiconductor Index, while SMH tracks the MVIS US Listed Semiconductor 25 Index. SOXX holds approximately 30 companies; SMH holds approximately 25.

In a market-cap-weighted fund like SMH, NVIDIA's enormous market capitalization translates into a large portfolio allocation, potentially representing 20% or more of the fund. This means SMH tends to deliver higher returns when NVIDIA surges and sharper drawdowns when NVIDIA corrects. SOXX's modified equal-weighting caps that exposure at approximately 8%, spreading the return profile more broadly across the chip sector.

SOXQ tracks the PHLX Semiconductor Sector Index, the same benchmark SOXX originally tracked before transitioning to the ICE Semiconductor Index. At approximately 0.19%, SOXQ is the lowest-cost option among major semiconductor ETFs. No single fund is categorically superior. SOXX may suit investors who prefer reduced single-stock concentration risk. SMH may suit investors who prefer market-cap weighting and welcome NVIDIA's heavier representation. SOXQ may suit investors for whom cost is the primary deciding factor.

SOXX vs. SOXL: Not the Same Fund

SOXX vs. SOXL: Not the Same Fund

SOXX is not a leveraged ETF, and it is not the same product as SOXL. The ticker similarity causes genuine confusion, but these are fundamentally different products designed for fundamentally different purposes.

SOXX is the iShares Semiconductor ETF: unleveraged, passively managed, tracks the ICE Semiconductor Index, 0.35% expense ratio, designed for long-term buy-and-hold investors.

SOXL is the Direxion Daily Semiconductor Bull 3X Shares: a 3x leveraged daily-reset ETF issued by Direxion (not BlackRock or iShares), approximately 0.76% expense ratio, designed for short-term traders. SOXL aims to deliver 300% of the daily performance of a semiconductor index. This daily reset structure causes a phenomenon called volatility decay: over periods longer than a few days, SOXL can significantly underperform three times the index return, and it can lose far more than three times the index loss in declining markets.

SOXS (Direxion Daily Semiconductor Bear 3X Shares) is the inverse counterpart to SOXL, providing 3x daily inverse exposure to semiconductor stocks, and is also not appropriate for long-term investors.

If you are researching long-term semiconductor sector exposure, SOXL is not the fund you are looking for.

Is SOXX ETF Right for You?

SOXX ETF suits a specific type of investor: one who wants concentrated semiconductor sector exposure, accepts higher volatility than a diversified index fund, and has a long investment horizon. The fund has genuine strengths and genuine limitations, and both deserve equal attention.

Pros of SOXX ETF

• Diversified semiconductor exposure across approximately 30 companies in a single purchase, spreading risk across fabless designers, IDMs, and equipment makers
• A 20-plus-year track record dating to July 2001, spanning multiple semiconductor cycles
• Institutional credibility through BlackRock's iShares platform, the world's largest ETF provider
• AI chip infrastructure exposure through multiple semiconductor supply chain positions including NVIDIA, AMD, and Broadcom
• Liquid market with approximately $10-12 billion in AUM, translating to tight bid-ask spreads and easy execution
• Modified equal-weighting limits single-stock concentration risk relative to market-cap-weighted alternatives like SMH

Cons of SOXX ETF

• Single-sector concentration risk: a semiconductor-specific downturn affects the entire portfolio simultaneously
• Higher volatility than diversified index ETFs, with a beta historically above 1.5 relative to the S&P 500
• Geopolitical risk exposure through TSMC and other holdings with China revenue or Taiwan manufacturing dependencies
• An expense ratio of 0.35%, while mid-range for sector ETFs, is higher than SOXQ's 0.19% for comparable semiconductor exposure
• Semiconductor industry cyclicality means inventory cycle corrections can produce drawdowns exceeding 35-40%
• Low dividend yield (0.5%-1.0%) relative to income-focused ETFs

SOXX ETF Risks

1. Sector concentration risk. SOXX holds only semiconductor and semiconductor equipment companies. A downturn specific to the chip sector, whether from inventory corrections, demand shortfalls, or earnings misses, affects the entire portfolio.

2. High volatility and high beta. Semiconductor stocks have historically carried a beta well above 1.0 relative to the S&P 500. SOXX drawdowns have exceeded 40% during major market corrections, including a decline of more than 35% peak to trough in 2022.

3. Geopolitical risk. Two distinct risk vectors affect SOXX. First, Taiwan Strait physical supply chain risk: Taiwan Semiconductor Manufacturing Company (TSMC, TSM), one of SOXX's major holdings, manufactures approximately 90% of the world's most advanced chips in Taiwan. A military conflict or blockade scenario in the Taiwan Strait would severely disrupt global semiconductor supply chains and would likely cause acute SOXX drawdowns. Second, U.S.-China semiconductor export controls: the U.S. government has imposed and expanded restrictions on exporting advanced semiconductors and chip manufacturing equipment to China. These controls directly affect SOXX holdings including NVIDIA (restricted GPU exports), Applied Materials, Lam Research, and KLA Corporation (equipment export restrictions), creating ongoing revenue uncertainty for multiple top holdings.

4. Semiconductor cyclicality. The chip industry follows boom and bust inventory cycles tied to capital expenditure trends and demand shifts across consumer electronics, automotive, and data center markets.

5. Valuation risk. High-growth semiconductor stocks can carry elevated price-to-earnings multiples. In risk-off market environments, multiple compression can produce sharp declines even when underlying business fundamentals remain intact.

SOXX May Be Appropriate for Investors Who:

• Seek diversified semiconductor and AI chip sector exposure in a single fund without picking individual chip stocks
• Have a long investment horizon (typically five or more years) and can tolerate sector-level volatility
• Prefer modified equal-weighting to limit single-stock concentration relative to market-cap-weighted alternatives
• Want exposure across all three sub-segments of the semiconductor industry in one position

SOXX May Not Be Appropriate for Investors Who:

• Cannot tolerate drawdowns exceeding 35-40%, which SOXX has experienced during major market corrections
• Have short investment horizons that cannot absorb sector-specific volatility cycles
• Seek meaningful dividend income; SOXX's 0.5%-1.0% yield is not suitable for income-oriented strategies
• Prioritize minimizing cost; SOXQ at approximately 0.19% offers comparable semiconductor exposure at significantly lower cost
• Prefer heavier NVIDIA concentration; SMH's market-cap weighting may better match that preference

Comparing SOXX to buying NVIDIA stock directly: SOXX limits maximum NVIDIA exposure to approximately 8% through modified equal-weighting, while owning NVDA stock directly means 100% concentration in a single company. The choice depends on whether an investor wants diversification across the chip sector or concentrated exposure to a single company's results.

How to Buy SOXX ETF

Buying SOXX ETF follows the same process as purchasing any stock or ETF through a standard brokerage account.

1. Open or log in to a brokerage account. SOXX is available through most major U.S. brokerages including Fidelity, Schwab, TD Ameritrade, Robinhood, and E*TRADE.
2. Search for ticker symbol SOXX. Enter the ticker in the search bar to bring up the fund's quote page.
3. Review the current share price and NAV. The market price and NAV of SOXX are typically nearly identical for a fund this liquid. For live price data, visit the iShares SOXX ETF fund page or your brokerage platform.
4. Choose your order type. A market order executes immediately at the current price. A limit order lets you specify a price target and will only execute if SOXX reaches that price.
5. Enter share quantity and submit the order. SOXX trades on NASDAQ during regular market hours, 9:30 AM to 4:00 PM ET.

There is no fixed minimum investment. You can buy as little as one share at the current market price. Some brokerages offer fractional shares, allowing you to invest a specific dollar amount regardless of the share price. Most major brokerages offer commission-free ETF trading, so the primary ongoing cost is the 0.35% annual expense ratio.

ETFs generally generate fewer capital gains distributions than mutual funds due to the in-kind creation and redemption mechanism, which can make SOXX suitable for taxable brokerage accounts. Individual tax treatment varies; consult a qualified tax advisor for guidance specific to your situation.

The fund experienced a drawdown exceeding 35% in 2022. Retrieve current figures from the iShares SOXX ETF fund page. Past performance does not guarantee future results.

What Is the Difference Between SOXX and SOXL?

SOXX is an unleveraged ETF tracking the ICE Semiconductor Index with a 0.35% expense ratio, designed for long-term buy-and-hold investors. SOXL (Direxion Daily Semiconductor Bull 3X Shares) is a 3x leveraged daily-reset ETF issued by Direxion (not BlackRock or iShares) with an approximately 0.76% expense ratio, designed for short-term traders. SOXL experiences volatility decay over multi-day holding periods and is not a substitute for SOXX.

How Many Stocks Does SOXX Hold?

SOXX holds approximately 30 semiconductor and semiconductor equipment companies. Modified equal-weighting caps each holding at approximately 8% of the portfolio, preventing any single stock from dominating the fund's returns. This makes SOXX a concentrated sector fund compared to broad index ETFs.

What Sector Is SOXX ETF?

SOXX belongs to the Information Technology sector, specifically the Semiconductors and Semiconductor Equipment sub-sector under the Global Industry Classification Standard (GICS). It is a pure-play semiconductor fund, not a broad technology ETF. SOXX does not hold software companies, internet platforms, or consumer electronics assemblers.

Is SOXX a Good ETF for AI Exposure?

SOXX provides diversified AI chip hardware exposure through NVIDIA (GPU leader), AMD (competing AI accelerators), Broadcom (custom AI chips for hyperscale customers), and Micron (high-bandwidth memory for AI servers). SOXX is a semiconductor ETF, not an AI ETF, and includes holdings across the broader semiconductor industry. If AI capital spending decelerates, SOXX's AI-related holdings face valuation risk alongside the rest of the portfolio.

The Bottom Line on SOXX ETF

SOXX ETF stands as one of the longest-established semiconductor sector funds, launched in July 2001 and backed by BlackRock's iShares platform, with a portfolio constructed to distribute chip sector exposure across approximately 30 companies rather than concentrating in a single holding. Its modified equal-weighting methodology is the feature that most clearly distinguishes it from SMH, keeping individual positions capped at approximately 8% and giving the fund a broader return profile across the semiconductor supply chain.

Investors drawn to SOXX typically combine a long time horizon with conviction in semiconductor demand growth, whether from AI infrastructure, consumer electronics, automotive electrification, or the full range of chip application markets. SOXX is not an income fund, not a low-risk diversified vehicle, and not appropriate for investors who cannot tolerate drawdowns in excess of 35-40%. For cost-sensitive investors, SOXQ at approximately 0.19% offers a lower-cost path to similar semiconductor exposure. For investors who want heavier NVIDIA concentration, SMH's market-cap weighting achieves that outcome.
