iShares Semiconductor ETF Sees Strong Performance
The iShares Semiconductor ETF (currently up +1.44%) is an exchange-traded fund that specifically invests in U.S. companies involved in the design and manufacture of chips and related components. It particularly focuses on firms within the artificial intelligence (AI) sector.
This focus has led to substantial gains for the ETF, including major holdings in companies like Micron Technology, Advanced Micro Devices, and Nvidia. So far in 2026, it boasts an impressive 108% return, significantly outperforming the S&P 500—which has seen an increase of only 10% this year.
But, is it too late for investors to join the iShares ETF party? The answer isn’t necessarily straightforward.
A Concentrated Portfolio
The iShares Semiconductor ETF is quite focused, holding only 30 stocks. Notably, its ten largest holdings make up 62.2% of its overall value. This lineup encompasses nearly all key players in the AI chip market.
| Stock | Portfolio Weighting |
|---|---|
| Micron Technology | 11.21% |
| Advanced Micro Devices | 8.98% |
| Marvell Technology | 8.06% |
| Intel | 6.43% |
| Broadcom | 5.63% |
| Nvidia | 5.46% |
| Applied Materials | 5.35% |
| KLA Corporation | 3.93% |
| Rambus | 3.69% |
| Qualcomm | 3.50% |
These ten stocks together have yielded an average return of 136% this year, making the iShares Semiconductor ETF a standout performer compared to the S&P 500.
Micron Technology is a major contributor to this success, driven by soaring demand for its high-bandwidth memory (HBM) essential for data centers, which play a crucial role in AI hardware. Micron is expected to report impressive fiscal results with a significant increase in sales and profits soon.
On the other hand, Intel has also excelled due to high demand for its data center CPUs. These chips can handle specific AI workloads better than GPUs, making them crucial for autonomous workflow planning. Moreover, Intel’s foundry sector is benefiting, as customers seek manufacturing capacity amid a global chip shortage.
Nvidia has seen its stock increase over 12 times since the beginning of 2023, although its growth has leveled off this year. Even so, the demand for Nvidia’s GPUs, which are vital for AI training and workloads, continues to exceed supply, leaving room for future price growth.
To Buy or Not to Buy?
The iShares Semiconductor ETF has consistently shown an annual return of 14.9% since its inception in 2001, outperforming the S&P 500’s average return of 8.5%. This indicates that outperforming the market this year may not just be a one-time event.
From this perspective, the ETF looks promising for a diversified portfolio, but caution is warranted, especially given the rapid increases in prices of some holdings like Micron. With an unmatched supply-demand imbalance in memory chips, Micron currently wields substantial pricing power. Yet, this might not last—as the industry works to ramp up production, pressures on growth and profitability may emerge.
Additionally, some signs of strain in demand are surfacing. For instance, executives from Alphabet and Uber Technologies have acknowledged challenges related to rising AI costs, which could lead to broader reductions in chip demand if this sentiment becomes widespread.
In summary, investing in the iShares Semiconductor ETF could still be a sound decision, given its solid track record. However, increased volatility appears likely, which may make a long-term investment horizon of five years or more crucial for potential investors.
