The present invention provides a unitary note investment instrument and method of use that has two performance components. An investor invests in the issuer the principal amount of the investment. The first component is a base portfolio. The second component is keyed to a passive commodity index, having long and short positions. The instrument's commodity index exposure is established as the product of a leverage factor of at least 100% and the amount of the base portfolio exposure. The return to the investor comprises the change in value of both the base portfolio exposure and the commodity index exposure over a predetermined period of time multiplied by a payout factor.
