Over the past 50 years, there have been 14 market corrections and 11 bear markets. The definition of a correction is a peak-to-trough decline of at least 10 percent and a bear market is a peak-to-trough decline of at least 20 percent.In terms of corrections, the mean time to recover was only 107 days, rewarding those with even modest levels of patience. The mean time to recovery for bear markets has been 738 days, but that was highly influenced by the six years it took to recover in the 1970s. Even the financial system crisis in 2008 required less time to recover.
