(Bloomberg) -- Some U.S.-based mutual funds focused on emerging-market stocks have done so well at limiting losses in 2015 that, by one measure at least, it’s been one of the sector’s best ever.

As the MSCI Emerging Markets Index heads for its third straight annual decline, 34 of 65 U.S. funds that track the benchmark had beaten it through last week, data compiled by Bloomberg show. That’s 52 %, up from 38 % in 2014, 49 % in 2013 and the fourth-highest percentage of outperformers in the past 15 years.
