August Almanac, Vital Stats & Strategy Calendar: Worst Performing Month of Past 27 Years By: By Christopher Mistal & Jeffrey A. Hirsch | July 28, 2015 | Email | Print

 

Contributing to this poor performance since 1987; the shortest bear market in history (45 days) caused by turmoil in Russia, the Asian currency crisis and the Long-Term Capital Management hedge fund debacle ending August 31, 1998 with the DJIA shedding 6.4% that day. DJIA dropped a record 1344.22 points for the month, off 15.1%—which is the second worst monthly percentage DJIA loss since 1950. Saddam Hussein triggered a 10.0% slide in August 1990. The best DJIA gains occurred in 1982 (11.5%) and 1984 (9.8%) as bear markets ended. Sizeable losses in 2010, 2011 and 2013 of over 4% on DJIA have widened Augusts’ average decline. A strong August in 2014 of S&P 3.8% and NASDAQ 4.8% preceded corrections of 7.4% and 8.4% respectively from mid-September to mid-October.

 

The first nine trading days of the month have exhibited weakness while mid-month is strongest. Note the bullish cluster from August 14-19. The end of August tends to get whacked as traders evacuate Wall Street for the summer finale. The last five days have suffered in 13 of the last 19 years with the S&P 500 up only four times on the next to last day in the past 19 years. In the last 19 years, the last five days of August have averaged losses of: Dow Jones Industrials, –1.3%; S&P 500, –1.2%; NASDAQ, –0.9% and Russell 2000, –0.3%.

 

 

On Monday of expiration the Dow has been up 13 of the last 20 times with four up more than 1%, while on expiration Friday it has dropped in 10 of those 20 years, down four of the last five years. Expiration week as a whole is down slightly more than half the time since 1990, but some of the losses have been steep (-2.6% in 1990, -2.3% in 1992, -4.1% in 1997, -4.0% in 2011 and 2.2% in 2013). The week after expiration is mildly stronger up 15 of the last 25.
