Looking forward to the next couple of months, equity markets are entering the weakest period of the year. Over the last 20 years, the S&P 500 index has averaged a loss of 0.20% for the month of September; positive results were realized in only 11 of the past 20 periods. The weak return in September ties it for the third weakest month of the year, behind February and August. The month that September ties with is June as investor reallocate portfolios at the end of the second quarter, just ahead of earnings season at the start of July. A similar reason is culprit for lackluster returns in September as the third quarter concludes. The weakest stretch of the entire year is a three week period that spans the last two weeks of September and the first week of October as investors buy and sell positions ahead of the volatile and uncertain third quarter reporting season.
