iShares Russell Midcap ETF

This ETF is one of several ETFs available that offers exposure to mid cap U.S. stocks, an asset class that can make up a significant portion of long-term, buy-and-hold portfolios. As such, this ETF may be more appealing to those in the portfolio construction process as opposed to short term traders. Mid cap stocks are appealing to many because they still have significant growth potential but they are less risky than their small and micro cap brethren. IWR offers exposure to a balanced portfolio of stocks, including close to 780 individual names, among the most in this particular Category. The expense ratio is pretty cheap, although there are several funds that do offer a lower cost. For those seeking other options in the space similar choices can be found in the MDY and IJH funds, the ultra-cheap FMM, and equal-weighted EWRM.
