The Dow Jones Industrial Average reached its trough on 9 March 2009 during the 2008–2009 global financial crisis.
The Dow closed at 6,547.05 that day, its lowest closing level since April 1997. The low came after a prolonged decline that followed the bursting of the U.S. housing bubble, the credit crisis, Lehman Brothers’ bankruptcy, and deepening recession.
From its closing peak of 14,164.53 on 9 October 2007, the Dow had fallen by roughly 54%. The market’s bottom did not arrive immediately after Lehman failed in September 2008; several more months of financial stress and worsening economic data followed.
The 9 March low is sometimes confused with the date of Lehman’s bankruptcy or with the S&P 500’s own market low, which also occurred on that date. Afterward, U.S. equities began a long recovery, although employment and broader economic conditions remained weak for some time.
