Schweihs The discounted cash flow method does not always completely capture the uncertainty of the future financial performance of a business, business ownership interest, or security that is the subject of a valuation analysis. In those instances, when the valuation purpose should take into consideration the owner/operator’s ability to influence the future financial performance of the subject investment, then real option valuation (ROV) theory is a powerful analytical tool. ROV analysis is often used by corporate acquirers—and by other investors— who are more interested in the question “what is this investment worth to me?” than they are in the question “what is the market value of this investment?” NTRODUCTION be justified by the intrinsic valuation of the subject I investment.
