NEW YORK (TheStreet) -- Here are this week's winners and losers.
First Trust Dow Jones Select MicroCap Index Fund ( FDM) 9.2% Small, volatile micro caps benefited as the markets found footing and powered higher. FDM managed to carve out some of the ETF industry's strongest gains. The four days of upward action the fund enjoyed over the past week has helped it recover and put it within reach of its September highs. Despite being one of the few micro cap-focused ETFs available, FDM has struggled in the past to gather investor attention. Those looking to gain exposure to this fund should use extreme caution.
