“Mid-cap stocks have been in the sweet spot of risk-adjusted performance since 1926,” according to Morningstar analyst Michael Rawson. “Although they historically have had a higher return than large caps, they have also had a higher volatility and a higher beta, or more procyclical movement with the market. But the higher return has compensated investors for the increased risk. While small caps had even higher returns, mid-caps have had a slightly better ratio of return to risk.”

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, mid-cap stocks are more volatile than their larger counterparts.

“Mid-cap stocks tend to be more volatile than their large-cap counterparts as they are less likely to sport economic moats or sustainable competitive advantages,” Rawson added. “As such, they tend to be more sensitive to the business cycle.”
