What this means for investors
When it comes to tech ETFs, there are a handful of stalwarts, and these are two of them. But which is the best?
The State Street Technology Select Sector SPDR ETF is a more concentrated portfolio that focuses on technology stocks within the S&P 500 only, while the iShares U.S. Technology ETF casts a wider net, looking at technology stocks within the Russell 1000. So, it includes both large-caps and mid-caps.
XLK has been the better performer year-to-date and over the past year by a significant margin. Its one-year total return is about 67% compared to around 59% for IYW. Over longer time frames, their five- and 10-year returns are roughly similar.
If you are looking for a more diversified portfolio of tech stocks that inlcudes mid-caps, then IYW might be preferable. But ultimately, XLK looks like the better option, mainly due to its lower fees. It has an expense ratio of just 0.08% compared to 0.38% for IYW.
