The above graph shows the bull and bear market durations. The bull market that ended with the financial crisis lasted 61 months, according to Morningstar’s chart, but the two prior runs were 153 months and 155 months long. In other words, stocks were in an uptrend for more than 12 years.
The chart also shows that bear markets are relatively quick, with the last two lasting 16 months and 25 months, respectively.
