Consider the following table of annual rates of return, in percentage, for four common risky assets over the time period 2010 to 2019 • Berkshire Hathaway (ticker: BRK/A) • S&P 500 Index (ticker: SPX) • NASDAQ 100 Index (ticker: NDX) • Russell 2000 Index (ticker: RUT) YEAR 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 BRK/A 21.4 -4.7 16.8 32.7 27 -12.5 23.4 21.9 2.8 11 SPX 15.1 2.1 16 32.4 13.7 1.4 12 21.8 -4.4 31.5 NDX 19.22 2.7 16.82 34.99 17.94 8.43 5.89 31.52 -1.04 37.96 RUT 26.85 -4.18 16.35 38.82 4.89 -4.41 21.31 14.65 -11.01 25.52 Now assume there is a risk-free asset available and the annual risk-free rate is 2%. Using mean-variance portfolio theory, determine the 4 portfolio weightings and the portfolio variance for the unique fund F defined by the tangent portfolio and the one-fund theorem.
