The US stock market has enjoyed a five-year bull run. Since starting its advance in March 2009, the S&P 500 has handed investors a total return, including re-invested dividends, of 209 per cent. If you'd played it safe and invested in bonds, your total return would be 28 per cent over the same period, according to the Barclays US aggregate index, which tracks the broader debt market. Fidelity's money market fund, which makes such investments, returned 4.1 per cent over the same period. The best-performing stocks in the S&P 500 index during the five-year bull market are a drugmaker, a hotel company and a broadcaster.
