September has just started and is already living up to its reputation of being the toughest month of the year for stocks.
The stock market sold off after the open and August's weak M-PMI report was released later on, which pressured equities further.

Investors might have decided to take some of their profits now and not wait for a Black Swan event to show up this month. Now we are back to thinking that stock prices could churn a while longer before resuming their climb.
