Systems and methods of generating a financial market index are disclosed. According to various embodiments, the index may use a fundamental economic indicator to determine a leverage factor. In various embodiments, the leverage factor is increased if the 3M USD LIBOR increases by at least ten basis points during a determined time period, otherwise the leverage factor is decreased. The leverage factor may have upper and lower bounds. The index level may be calculated daily, with the rebalancing occurring on a monthly cycle.
