The Standard & Poor's 500 Index (often referred to as S&P 500) is a weighted average of prices of highly traded stocks in the United States. Suppose there is a portfolio indexed to the S&P 500 and another one indexed to the price of gold. The accompanying table shows historical data from the period 1982-2010, which suggest the expected value of the annual percentage returns associated with these portfolios. Portfolio S&P 500 Gold (fine ounce) Expected value of return (percent) 8.5 5.1 Which portfolio would a risk-neutral investor prefer? S&P 500 Gold What can be inferred about the risk of the two portfolios if a risk-averse investor chooses to invest in gold?
