The Vanguard Information Technology ETF and the iShares U.S. Technology ETF both offer investors streamlined access to U.S. tech sector stocks, but key differences in cost structure, portfolio composition, and dividend yield set them apart. According to recent data as of March 2026, VGT charges an expense ratio of just 0.09% annually, significantly lower than IYW’s 0.38% fee, while also delivering a dividend yield of 0.4% compared to IYW’s 0.2%.
Both technology ETFs track leading U.S. tech companies and rank among the largest sector-focused funds in the market. VGT manages approximately $110.1 billion in assets under management, dwarfing IYW’s $19.1 billion, according to the latest fund data. Despite the size difference, both funds have demonstrated strong performance over the trailing 12-month period, with IYW posting a 35.5% return compared to VGT’s 34.0%.
Portfolio Construction and Technology ETF Holdings
The structural differences between these funds reveal distinct approaches to technology sector exposure. IYW holds approximately 140 U.S. stocks with a notable 9% allocation to communication services companies alongside its core technology holdings, according to the fund’s latest disclosures. Meanwhile, VGT maintains a more concentrated portfolio of 310 stocks with 98% dedicated to pure technology companies and minimal exposure to other sectors.
Both funds share similar top holdings, including Nvidia, Apple, and Microsoft, though the weighting differs slightly between the two. This overlap reflects the market dominance of mega-cap tech companies in the sector. However, VGT’s broader stock count may provide slightly more diversification within the technology space compared to IYW’s more selective approach.
Risk Profile and Historical Performance
Risk metrics reveal subtle differences in volatility characteristics between the two funds. According to five-year data, VGT experienced a maximum drawdown of 35.08% during the measured period, while IYW saw a deeper decline of 39.44%. Both funds exhibit beta values above 1.2, indicating higher volatility relative to the broader S&P 500 index.
Additionally, long-term performance data shows VGT has generated a compound annual growth rate of 13.9% since its 2004 inception, slightly outpacing IYW’s 13.5% CAGR since 2000. Over a five-year period, a $1,000 investment in IYW would have grown to $2,226, compared to $2,059 for VGT, according to recent calculations.
Cost Considerations for Technology ETF Investors
The expense ratio difference between these funds represents a significant factor for long-term investors focused on cost efficiency. VGT’s 0.09% annual fee means an investor would pay just $9 per year on a $10,000 investment, while IYW’s 0.38% fee translates to $38 annually on the same amount. Over decades, this cost differential can compound into substantial savings that enhance total returns.
In contrast, IYW’s higher fee structure may be justified by some investors who prefer its specific index methodology or communication services exposure. The fund’s 25-year track record also provides extensive historical data for evaluation. Neither fund employs leverage, hedging strategies, or environmental, social, and governance screening, keeping their approaches straightforward.
Choosing Between Technology Sector Funds
For investors seeking pure technology sector exposure with minimal cost drag, VGT appears positioned as the more economical choice with its rock-bottom expense ratio and higher dividend yield. However, IYW’s communication services allocation and slightly different stock selection may appeal to investors seeking a specific approach to tech investing. Both funds provide efficient access to the growth potential of U.S. technology companies through a diversified basket of holdings.
The decision between these technology ETFs ultimately depends on individual investor priorities regarding cost sensitivity, sector purity, and portfolio construction preferences. Both funds continue to track their respective benchmarks without significant strategy changes expected in the near term, allowing investors to evaluate them based on current characteristics rather than anticipated modifications.
