Invesco PHLX Semiconductor ETF (SOXQ)
The semiconductor industry is the hidden engine of modern technology. Behind every smartphone, data center, and AI accelerator is a chip. The companies that design and manufacture these chips sit at the intersection of every significant computing trend, from artificial intelligence to cloud computing to consumer electronics. The Invesco PHLX Semiconductor ETF (SOXQ) offers investors a concentrated way to own the largest American semiconductor firms in a single fund.
SOXQ launched in June 2021 and tracks the PHLX Semiconductor Index, a modified market-capitalization weighted index compiled by Nasdaq that includes the 30 largest U.S.-listed companies engaged in the semiconductor business. The fund is passively managed, meaning it holds the index constituents in proportion to their weight in the index, rebalancing periodically to maintain that alignment. Invesco, one of the world’s largest asset managers, runs the fund. With over 17 billion in assets under management, SOXQ is liquid and well-established within its category.
The semiconductor sector is famously cyclical. Chip demand rises when corporations and consumers invest in technology, and falls when they pull back. But over the past decade, artificial intelligence, cloud computing, and data analytics have created new, sustained demand for chips. The rise of machine learning training and inference workloads has made semiconductors not just useful but essential infrastructure. SOXQ’s investors are betting that semiconductor companies will remain central to economic value creation for years to come.
The 30 companies in the index
SOXQ’s portfolio concentrates heavily in the largest chip firms. The top 10 holdings represent about 61% of the fund’s assets, reflecting the index’s market-capitalization weighting. The largest holders typically include major designers like Nvidia (which makes AI accelerator chips), Intel (the traditional PC and data center chip leader), Advanced Micro Devices (AMD), and Broadcom (an infrastructure chip company). These are followed by firms like Qualcomm (mobile and wireless chips), Marvell Technology (storage and data center chips), and Micron Technology (memory chips). Smaller positions round out the index to 30 companies total.
This composition captures the entire semiconductor value chain. The fund holds pure design companies—firms that design chips but outsource manufacturing—as well as contract manufacturers like Taiwan Semiconductor Manufacturing Company and integrated manufacturers like Intel that design and fabricate their own products. It also includes equipment makers like Applied Materials and ASML, which build the tools used to manufacture chips. This diversity within the semiconductor sector is a form of diversification, though the fund remains a sectoral bet, not a broad market bet.
The geographic exposure reflects reality: while SOXQ is a U.S.-listed fund holding U.S.-listed companies, about 10% of the portfolio in foreign securities reflects the globalized nature of chip manufacturing. Many American semiconductor companies derive significant revenue from Asia, and some maintain manufacturing capacity overseas.
Why investors own this fund
SOXQ is for investors who believe semiconductors will remain economically important and that U.S. semiconductor companies will continue to profit from that importance. The reasoning has several layers. First, artificial intelligence is computationally hungry. Training large language models and running inference on billions of queries requires powerful chips. Nvidia’s recent surge in market value reflects investor confidence that AI workloads will sustain chip demand. SOXQ gives exposure to Nvidia and the rest of the sector without picking a single winner.
Second, semiconductors are supply-constrained. The ability to manufacture chips is not easy to replicate—it requires billions of dollars, years of engineering, and scarce expertise. The companies that can make chips have pricing power and durable competitive advantages. The U.S. government has even begun investing in domestic chip manufacturing capacity because of the strategic importance of not relying entirely on Asia for this critical input.
Third, the semiconductor sector has been a source of long-term capital appreciation. Companies that innovate in chip design and manufacturing tend to grow earnings over time, rewarding patient investors.
The challenges and limitations
SOXQ is not without risks. Semiconductors are cyclical. When companies and consumers stop upgrading their computers and servers, chip demand collapses. A recession would likely hit semiconductor stocks hard. The recent surge driven by AI enthusiasm could also reverse if companies deploy models and then pull back on capital spending.
The sector is also capital-intensive. Manufacturing chips requires enormous factories—fabs—that cost tens of billions of dollars. A single fab operating below capacity can destroy profitability for years. Demand forecasting is notoriously difficult, and companies frequently end up with too much or too little capacity.
Competition is also intense. Chip companies must spend heavily on research and development to avoid obsolescence. A company that fails to innovate loses market share rapidly. Intel, once the undisputed semiconductor leader, has struggled in recent years as AMD and others took share. This dynamism means that index-tracking a 30-company list captures winners and laggards alike.
Geopolitical risk is real. The U.S. government restricts the export of advanced semiconductors to certain countries, particularly China. A trade war or further escalation of restrictions could disrupt markets. Additionally, much semiconductor manufacturing occurs in Taiwan, which faces geopolitical tensions with China. Any disruption to Taiwan would shock global chip supply.
How the fund is structured
SOXQ has an expense ratio of less than 0.10%, reflecting its passive index-tracking approach. This low cost is a major advantage over actively managed funds and is typical for broad ETFs. The fund holds at least 90% of assets in the securities that comprise the PHLX index, with small cash positions for operational efficiency.
Trading on the NASDAQ exchange under the ticker SOXQ, the fund is highly liquid. Daily volume is typically in the millions of shares, meaning investors can buy or sell substantial positions without moving the price significantly. The bid-ask spread—the difference between what you pay to buy and what you receive to sell—is tight, usually pennies on large positions.
The fund pays no meaningful dividend. Semiconductor companies rarely distribute cash to shareholders. Instead, returns come from share price appreciation as the companies grow earnings and investors’ valuations of those earnings shift.
Comparing SOXQ to SOXX
Investors interested in semiconductor index exposure might also encounter SOXX, the iShares PHLX SOX Semiconductor ETF, which also tracks a PHLX semiconductor index. The two funds are broadly similar in holdings and objective but differ in issuer, size, and age. SOXX is larger and has been around longer, while SOXQ is slightly newer. Both offer low-cost exposure to the same basic strategy. The choice between them is often about personal preference or account consolidation.
Researching the fund
Begin with the fund’s prospectus and fact sheet. These documents explain the index composition, the fund’s holdings, the expense ratio, and risk factors. Invesco publishes detailed quarterly holdings reports that show exactly what the fund owns.
Monitor semiconductor industry cycles. Watch quarterly earnings from Nvidia, Intel, AMD, and ASML for signs of demand strength or weakness. Read industry commentary from semiconductor analysts. Track government policy around chip manufacturing incentives and export controls, as these affect the regulatory environment semiconductor companies face.
Finally, think carefully about your time horizon. Semiconductors are cyclical, so short-term volatility is high. But if you believe that computing and artificial intelligence will remain central to the economy for the next 10 years, SOXQ offers a simple, low-cost way to own a broad slice of the companies making that possible.
