At 4.4 years old, the post-March 2009 rally is already older than both the post-World War II and post-1900 bull market averages of 4.2 years and 3.5 years, respectively. In addition, the Dow's 136% rally off of the March 2009 low close now exceeds the post-World War II average of +128%, and falls just shy of the post-1900 average of +141%. As is clear from the chart below, the US equity market's post-March 2009 rally is close to being on the verge of becoming an outlier... so BTFATH?
