A rating method for securities or fixed rate financing instruments includes calculating a rating value for each one of the securities or fixed rate financing instruments based upon a formula involving grading numbers and weighting factors corresponding to risk and return attributes. The return attribute may be an interest rate, a dividend yield, a yield to maturity, a project performance rating of an issuer, or a ratio defined with a price per share of securities. A method for evaluating a price of a security or fixed rate financing instrument includes calculating an evaluated price based upon a formula involving grading numbers and weighting factors corresponding to each of real-time data including a face value, a coupon, a period prior to maturity, a credit rating of an issuer, a yield, and a yield to maturity; and comparing the evaluated price with a real-time price.
