Friday the 13th... Is it Good Luck for Stocks? VERY INTERESTING!

This is my own original research! I was checking the last 10 trading days for Friday the 13th activity just because it is such a "bad luck" day and all. For the last 10 trading days that fell on Friday the 13th we need to go back to June of 2003. We have been UP 6 of the last 10 trading sessions on Friday the 13th, and for a net GAIN. Could this predict today's activity? Unlikely but it sure would be nice to finish up. So here is the data I have for the last 10 days we have traded (in terms of the S&P 500).

February 13, 2009 -8.35
June 13, 2008 +20.16
July 13, 2007 +4.80
April 13, 2007 +5.05
October 13, 2006 +3.39
January 13, 2006 +1.55
May 13, 2005 -5.31
August 13, 2004 +1.57
February 13, 2004 -6.30
June 13, 2003 -9.90

As of right now we are borderline flat on the S&P down 1.08. But if the trend continues, odds are we finish up today, making it a 4 day winning streak. Certainly odd in this market lately...

Now for the Extremely odd! The sum of the last 10 trading days on Friday the 13th for the S&P 500 is a net gain of 6.66 or as some call the devil's number... Now wouldn't it be strange if the S&P finished the day unchanged? I guess we'll find out soon enough...
