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.
iShares MSCI Brazil Index Fund ( EWZ) -1.9% Brazil-tracking ETFs are taking hits at the start of the week in negative territory, with EWZ tumbling to its lowest level since the start of February. This decline has pushed the fund to its 50-day moving average; in the days ahead, it will be interesting to see if this level proves to be one of support.
