The fund normally invests at least 80% of assets in common stocks included in the index. The advisor uses statistical sampling techniques that take into account such factors as capitalization, industry exposures, dividend yield, price/earnings (P/E) ratio, price/book (P/B) ratio, and earnings growth to create a portfolio of securities listed in the index that have a similar investment profile to the entire index. The advisor lends securities to earn income for the fund.
