The first two inputs for the Jensen’s alpha indicator are used to identify the risk-free interest rate and the overall market. The risk-free rate is defined as the 13-week Treasury bill rate, while the overall market is defined as the S&P 500. If you want to change the default risk-free rate and overall market symbol, you can adjust the first two inputs by changing the symbols inside the quotation marks. The third input, “N,” is used to define your beta length.
