To obtain greater diversification for your investments you consider forming a portfolio from two stock index funds, one that tracks the S&P 500 (SPX) and the other is the Schwab International Index Fund (SWISX) that tracks large stocks in markets around the world. Over the next year, the S&P 500 has an expected return of 14% and a standard deviation of return of 30%. The SWISX has an expected return of 18% and a standard deviation of return of 27% (in U.S. $ terms). Assume that the indices have a historic correlation of 0.20 and that is expected to hold in the near future.
