October has historically been an unsettling time for investors. Not only did the stock market crash of 1929 occur during the month, but the loss in October 2008 during the height of the credit crisis was the worst since . . . you guessed it, October 1987's crash. This year's witching month also had no shortage of drama, brought on by concerns about Ebola, ISIS, tumbling oil prices, economic troubles in Europe, and anxiety about tighter monetary policy.
