Concern over a global market slowdown and geopolitical risks kept equities markets and stock exchange traded funds relatively unchanged since the start of the year, but the S&P 500 Index is still heading toward its fifth quarterly gain, albeit a small one.

The Dow Jones Industrial Average declined 1.0% over the first quarter. Meanwhile, the Nasdaq Composite dipped 0.5% and the S&P 500 rose 0.5%.

The top performers over Q1 include exchange traded notes: the iPath Dow Jones-UBS Coffee Total Return Sub-Index (NYSEArca: JO) up 65.0%,  iPath Pure Beta Coffee ETN (NYSEArca: CAFE) up 59.4% and PowerShares DB Agriculture Long ETN (NYSEArca: AGF) up 38.8%.
