Smaller stocks, including mid caps, are usually more volatile than large-cap names. In November, that trend shifted in favor of mid caps as large-cap stocks became more volatile.

The SPDR Mid-Cap 400 (NYSEArca: MDY) is among the exchange traded funds tracking the widely followed S&P MidCap 400 Index.

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, along with providing more stable stock prices. Additionally, they are not so big that their size would slow down growth.

“While the S&P MidCap 400 risk of 19.1% and S&P SmallCap 600 risk of 21.8% were also elevated ending Nov. 30, 2018, it is interesting to note the large-cap risk was higher than the mid-cap risk.  The last November when this happened occurred in 2007,” said S&P Dow Jones Indices in a note out Monday.
