One of its members was Thomas Jefferson, a lawyer from Virginia. He had been a leader in Virginia, and Virginia had elected him to the Continental Congress.

The time frame is in weeks, so it shows the average bull market cycle is 155 weeks or about 39 months. The average bear market is about 17 months, which actually matches the most recent bear market from October 2007 to March 2009 (17 months). A full market cycle is 56 months.
At least, thatâs the conclusion I draw from looking at the history of corrections of the S&P 500 Index based on daily data going back to December 30, 1949. Now that major indexes have officially entered correction territory, investors are wondering how long corrections tend to last. Letâs start with the worst-case scenario of a bear market. If a bear market is a move of 20% or more from peak-to-trough and a correction is a move of 10% to just under 20%, then the average bear market is a drop of 31.6% (median of 30.3%). I donât think this is the start of a bear, though.
