The S&P 500 Index ("S&P 500") is a well-known, unmanaged index of the prices of 500 large-company common stocks selected by Standard & Poor's. The S&P 500 includes the reinvestment of all dividends, no transaction costs, and represents the gross returns before management fees.

The performance calculations for the Profit Track strategies were produced through the backtesting feature of the Research Wizard using the DBCMHIST database and consist of the total return (price changes + dividends) of an equal weighted portfolio. Returns are calculated on a specified periodic basis (four weeks for all Profit Track strategies except for Growth and Income and High Rank Value, which use a 24-week holding period) and assume no transaction costs. Each strategy is rebalanced at the start of each new period. Returns can be stated as either annualized or compounded. Stock trading/investing involves risk and you can lose some or all of your investment. Hypothetical or backtested results may not always be duplicated in the real world. Backtesting can at times produce an unintended look-ahead bias. Results can also at times be over or understated due to the exclusion of inactive companies. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk in actual trading, not the least of which is the ability to withstand losses or to adhere to a particular trading strategy in spite of trading losses. These are material points which can also adversely affect actual trading results. The backtested results prepared for the Profit Track strategies were done using the DBCMHIST database and consisted of only active companies. The Research Wizard program has been aligned, to the extent possible, to eliminate look-ahead bias. Zacks however cannot make any guarantees in regard to this or any other possible limitation.
