As we all (supposedly) know, chasing performance generally isn’t a wise investment strategy, and that past performance doesn’t guarantee future results. Still, it’s instructive—and fun—to see which exchange-traded funds are kicking butt and which ones are getting their butts kicked. Regarding the former, the top-10 performing funds year-to-date through September 20, as compiled by ETF researcher XTF.com, reveal that cutting-edge technology, the internet, China and Brazilian small caps have been the most successful investment themes so far in 2017. Many of the very best performing funds are those that employ inverse or leveraged strategies, which can magnify gains (and losses). The top-10 ETFs listed below in ascending order of YTD performance exclude those types of funds, and instead focus on ETFs that play it straight, so to speak:


10. First Trust China AlphaDEX Fund (FCA) – 59.34%
