Then again, the PowerShares S&P MidCap Low Volatility (NYSEArca: XMLV) has its advantages. XMLV tracks the performance of the S&P MidCap 400 Low Volatility Index, which tracks 80 of the least volatile stocks from the S&P MidCap 400 Index over the last 12 months and weights holdings based on the securities’ inverse volatility, so the least volatile securities have the highest weighting.
Mid-cap companies are slightly more diversified than their small-cap peers, which allows many mid-sized companies to generate more consistent revenue and cash flow and provide more stable stock prices. Additionally, they are not so big that their size would slow down growth.
The mid-caps segment has also outperformed their large-cap peers, but with lower volatility than small caps. Moreover, the returns of mid-cap stocks have also beaten those of small-cap stocks during the trailing three-, five-, and 10-year periods, with lower volatility.
“However, risk-adjusted return is critical when comparing investments. Absolute return is useless because you are examining it in a vacuum. It’s one thing if a fund outperforms its peers 3,000 bps because it holds incredibly risky stocks that all have a good year. It’s another thing if the fund outperforms more modestly but with significantly less risk,” according to a Seeking Alpha analysis of XMLV.
