Depending on how you look at it, August may not have been as bad a month for stocks as advertised. For the month as a whole, the MSCI all-country world stock index  lost more than 7.5 percent.  This was the worst performance since May last year, and the worst August since 1998.

But if you had bought in at the low on August 9, you would have gained  healthy 8.5 percent or so.
