Market Capitalization Breakdown - Morningstar separates stock portfolio holdings into five market-capitalization groups: Giant, Large, Mid, Small, and Micro. Of the 5000 largest domestic stocks in their equities database, the top 1% are categorized as Giant, the next 4% are Large, the next 15% are Mid, the next 30% are Small, and the remaining 50% are Micro. Stocks outside of the largest 5000 are also classified as Micro.
Weighted Average Market Cap - The average market capitalization of all companies held in the portfolio with each company weighted according to its percent held in the portfolio. The result is based upon a weighted average of the securities held in the fund.
P/B Ratio - A ratio that helps determine whether a stock is undervalued or overvalued. It is calculated by dividing a stock's price per share by its book value per share. The result is based upon a weighted average of the securities held in the fund.
P/E Ratio - Is the weighted average of each holding's P/E ratio (price of a stock divided by its earnings per share). The result is based upon a weighted average of the securities held in the fund.
Portfolio Turnover - This is a measure of the Fund’s trading activity which is computed by taking the lesser of purchases or sales divided by average monthly market value, excluding short-term investments. The resulting percentage represents the percentage of the portfolio’s holdings that have changed over the past year.
