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.
Although many expect the nation to avoid a downgrade, the German market-tracking iShares MSCI Germany Index Fund ( EWG) is taking a hit as well. iShares MSCI Mexico Investable Market Index Fund ( EWW) -2.7% Latin American nations are struggling in Friday's choppy trading environment, pushing ETFs linked to Chile, Peru, Brazil and Mexico into negative territory. EWW's ample exposure to non-cyclical sectors like consumer staples and telecommunications may make it appealing during periods of questionable performance. Caution is still warranted here, however, due to the fund's top-heavy nature. America Movil ( AMX) and Wal-Mart de Mexico together account for nearly a third of the fund's assets.
