The iShares MSCI All Country Asia ex-Japan (AAXJ) - Get Report is up over 12% year-to-date, more than double the return of the S&P 500. And it is doing it with far less volatility than other funds with similar risk, said Jason Browne, chief investment officer of FundX Investment Group. Browne is also bullish on the Vanguard FTSE Emerging Markets ETF (VWO) - Get Report , which is up 16% thus far in 2016. He said the VWO offers investors a diversified exposure to emerging markets that struggled last year, but have started to gain traction in 2016 even "in the face of fears of a Federal Reserve rate hike." Finally, Browne is a fan of the SPDR Barclays Convertible Securities ETF (CWB) - Get Report , up 6% so far in 2016. He said he likes the exposure to growth companies "with some yield to chew on while you wait for them to take off."
