NEW YORK ( TheStreet) -- Welcome to Don Dion's "ETF Winners and Losers." Be sure to stop by throughout the week to find out which ETFs are gaining or losing.
Teucrium Corn ETF ( CORN) -1.2% Corn futures prices are taking a hit at the start of the week, pushing CORN and other grains-focused exchange traded products to notable losses. The iPath Dow Jones UBS Grains Subindex Total Return ETN ( JJG) is off around 1%. Corn's weakness is not enough to drive the broad-based PowerShares DB Agriculture Fund ( DBA) into negative territory. This futures-backed fund has enjoyed four consecutive days of gains.
