Some might argue Berkshire Hathaway owned a fully diversified portfolio of businesses in conjunction with a large (and partially diversified) investment portfolio. If true, one could justifiably calculate the Sharpe ratio for Berkshire Hathaways Class A shares (ticker symbol BRK-A). Using one or more online sources, determine the annualized total return (i.e., including dividends reinvested), volatility and Sharpe ratio of for BRK-A the five years ending December 31, 2020 (i.e., 2016 - 2020 inclusive). [Note: you should use monthly return data to calculate the volatility. Assume an average annual yield of .50% for U.S. T-Bills.] Does this Sharpe ratio compare favorably to the historical Sharpe ratio for U.S. stocks? Briefly explain your answer.
