A computer implemented investment product includes data stored on one or more computers that corresponds to a notional performance portfolio of assets. The notional performance portfolio includes: (a) a base portfolio of assets having a selected exposure amount; (b) a passive commodity index portfolio, of long and short positions, having a passive commodity index portfolio exposure in an amount substantially equal to a product of the selected exposure amount multiplied by a leverage factor of at least 100%; and (c) the notional performance portfolio having a lower risk and a higher return as compared to either the base portfolio or the passive commodity index portfolio. The one or more computers monitor the base portfolio and the passive commodity index portfolio and calculate the return for the notional performance portfolio.
