This paper presents an approach to portfolio selection using fuzzy decision theory. The approach is such that a given target rate of return is achieved for an assumed market scenario. If the assumed market scenario turns out to be incorrect, the portfolio is guaranteed to secure a given minimum rate of return. The methodology is useful in the management of assets against given liabilities or in forming structured portfolios that guarantee a minimum rate of return.
