Calculating beta of portfolio.
The single-index model (SIM) is a simple asset pricing model to measure both the risk and the return of a stock.The model has been developed by William Sharpe in 1963 and is commonly used in the finance industry. Mathematically the SIM is expressed as: = + + (,)where: r it is return to stock i in period t r f is the risk free rate (i.e. the interest rate on …
