Program Description Using price and dividend information (from up to five shares), for three economic conditions, the program first calculates annualised returns. Then, given a risk-free rate of investment, the program calculates the opportunity set and super-efficient portfolio ratios to the nearest 5%. An overview of the main program processes is shown in the diagram below. Sample data is pre-loaded for most of the inputs for a Quick Start. Details of the input data formats are described in the Data Input section.
