Greg Lesko: Will There Be An October Surprise From Wall Street
"For the financial world, October is when some of the worst disasters happened on Wall Street. The big crash of 1929 that led to the depression occurred in October.
In 1987, the largest daily plunge in the Dow ever, over 22% known as "Black Monday" was also in October. And during the financial crisis of 2008, there was a frightful 19 day span when four of the five biggest point drops in the Dow's history brought the it down over 2600 points in October."
