Over the last 21-year period the last trading day of the third quarter has been bearish. DJIA and S&P 500 have advanced just 33.3% of the time with average losses of 0.12% and 0.04% respectively. NASDAQ and Russell 2000 have performed slightly better, but still have declined more frequently than advanced. The best year for the last trading day of the quarter was in 2008 while 1998 and 2011 are essentially tied for worst. From 2006 through 2014 (nine years) the last trading day of the third quarter was only up once. Performance has been improving lately with all four indexes posting gains over the last three years.
