Wondering what might happen in the stock markets this month? Many think October (and some think August) is typically the weakest month for the Dow Jones Industrial Average. However, reading from the data, the chart above (Source: dshort.com) shows that September has historically been the weakest month since 1928. Additionally, according to dshort.com, September has averaged -1.3% in the DJIA since 1929.
Keep in mind history is not always a foreteller of the future. Consider last September in 2010 when the DJIA actually increased 7.7% (Source: Bloomberg). However that move could have been event-driven by the Federal Reserve “leaking out” in late August their intention to “flood” the markets with fresh money through QE2.
Only time will tell what will happen this September.
