This Week's ETF Winners & Losers

Retail-related ETFs also finished with losses for the week. Late Monday, home improvement retailer Lowe's (LOW Quote) issued a profit warning, saying it now expects fiscal-year earnings at the low end or slightly below its previous guidance due to regional drought conditions hurting its outdoor offerings.
