Balancing Market Capitalization
Classifying by market capitalization
Stocks can be classified by the market capitalization of the underlying company.
Morningstar, a leading third-party provider of mutual fund investment information, defines a company's capitalization size using three categories: large cap stocks, small cap stocks1, and in between, mid-cap stocks. Morningstar resets the boundaries of these definitions periodically by examining the relative sizes of their database of stocks.
Over time these three categories have demonstrated different levels of volatility and investment returns. Looking at the market capitalization focus of funds is another way to examine the diversification in your portfolio.
