Estimate the WMT cost of equity capital using the following data sources: adjusted closing prices from Yahoo, MKT-RF and RF from the monthly and annual Fama-French factors files from Ken French’s data library, and the 1-month T-bill rate from FRED - install and use the Yahoo Finance API for this. Then, get the 1-month T-bill rate on March 1, 2024. Use the last 120 months for which all variables are present to compute the beta (remember to subtract RF from the WMT return before running the regression). In general, follow our March 19 conversations. Write a brief report of your results. Include a scatter plot with excess WMT returns (return minus risk-free rate) on the y axis and MKT-RF on the x axis. Include the regression line in the scatter plot.
