Headline: Commodities have the biggest returns year-to-date through April
Paragraph: After declining 17.01% in 2014 and 24.66% in 2015, commodities have bounced back in 2016. Gold and crude oil are up around 20% year-to-date April 30. Long-duration corporate bonds also have risen sharply as interest rates have fallen. European equities fell around 5% for the first four months of the year, but a stronger euro pushed U.S. dollar returns close to zero.
