What's inside
The Technology Select Sector SPDR Fund holds 69 companies, focusing almost exclusively on technology (98%) with minimal exposure elsewhere. Top positions include Nvidia (NASDAQ:NVDA), Apple (NASDAQ:AAPL), and Microsoft (NASDAQ:MSFT), each representing a significant portion of assets. With over 26 years of history and nearly $93 billion in assets under management (AUM), XLK offers highly liquid, blue-chip tech exposure.
In contrast, the iShares US Technology ETF holds 141 stocks, spreading exposure more broadly across technology (89%), communication services (9%), and a small slice of consumer cyclical. Its top holdings mirror XLK’s, but IYW’s broader sector allocation and larger roster may appeal to those seeking slightly more diversification within the U.S. tech universe.

Foolish take
When you look at XLK and IYW side by side, it’s clear they aim to do the same job: give investors exposure to the leaders of America’s technology sector. They hold many of the same mega-cap names and have delivered similar long-term growth patterns. Yet, they take two distinct approaches to building that exposure, and that’s where the fundamental differences start to matter for investors.
XLK takes a more concentrated approach and does so at a significantly lower cost, a combination that can be beneficial for investors seeking a straightforward and long-term tech allocation. IYW, on the other hand, casts a wider net. It includes a broader mix of technology and communication-services companies and holds more than twice as many stocks as XLK. That added breadth has contributed to slightly stronger recent performance, though it comes with a higher expense ratio and a smaller asset base. For investors who prefer a more diversified slice of the tech ecosystem and are willing to pay more for it, IYW offers a reasonable alternative.
For investors, the choice between the two ultimately depends on what you want your tech exposure to accomplish. If you prefer a fund that channels most of its weight into the largest and most stable tech companies, XLK aligns with that approach and does so at a lower ongoing cost. Suppose you believe diversification within tech can reduce portfolio risk or capture opportunities beyond the mega-cap leaders. In that case, IYW offers a broader range of holdings and a more extensive sector footprint.
Both funds serve the same purpose, and the better choice is simply the one that fits the role you want technology to play in your portfolio.
