Great chart with all the right colors from our friends over at The Chart Store.  They have an amazing collection of financial and economic charts and data going way back.

Tough to trade on historic average monthly returns.   The chart shows that August has historically been the best month for the Dow.

This August?  Down 4.36 percent.  Followed by a horrendous September, down 6.03 percent, setting up the monster October run with the Dow rising 9.54 percent.
