What’s inside
IYW tracks the U.S. technology sector, holding 140 stocks. Its sector allocation is 89% technology, with small allocations to communication services, industrials, and consumer cyclical, and its top holdings include Nvidia, Apple, and Microsoft. The fund was launched 25 years ago, offering investors a long track record and broad diversification within tech and related segments.
By contrast, XLK is focused almost exclusively on technology stocks. It holds just 71 positions, with 99% of assets devoted to tech. Its top three holdings match IYW’s, and having launched around 28 years ago, it offers a similarly long history.

What this means for investors
Both XLK and IYW provide access to leading U.S. technology companies, but their difference in diversification is an important factor for investors to consider.
IYW holds roughly twice as many stocks as XLK, but it leans more heavily on its top holdings. While both funds share the same top three stocks, those positions make up 44.43% of IYW’s portfolio compared to 37.91% for XLK.
This means that while IYW provides exposure to a broader swath of the tech sector and related industries, it’s more concentrated on mega-cap tech giants. If Nvidia, Apple, and Microsoft significantly under- or overperform, it will likely affect IYW more than XLK.
Case in point: IYW has experienced a steeper five-year drawdown, but it’s also slightly outperformed XLK in one- and five-year total returns.
Fees and income are other factors to consider with these two funds. XLK has an edge on both fronts, with a lower expense ratio and higher dividend yield. Investors can expect to pay $8 per year in fees for every $10,000 invested in XLK, compared to $38 per year for every $10,000 in IYW. While it’s a marginal difference on the surface, it can add up for long-term investors.
