In the unlikely event that you require another reason to root against that most loathsome of teams, remember what happened last time they won the World Series.

A National League team has won the World Series 33 times dating back to 1936. In the year following an NL victory, the S&P 500 has averaged a 14.3% gain, according to the data-crunching prowess by Richard Peterson, a director at S&P Capital IQ. That includes this year’s 24% rally after the San Francisco Giants, a National League squad, won the 2012 World Series.

By comparison, the S&P 500 has averaged a 9.3% increase in the 43 years after an American League franchise claimed the World Series….

Still, a deeper dive into the data shows bullish investors should support St. Louis. When the Cardinals have been victorious in America’s pastime, the S&P 500 has averaged an 8.3% gain. In the two instances in Mr. Peterson’s dataset when the Red Sox won the World Series – 2004 and 2007 – the stock market has generated mixed results.

The S&P 500 rose 3% the year after the Red Sox broke their 86-year curse in 2004. But the market plunged 38% in the year after Boston’s 2007 victory due to the financial crisis. That marked the worst performance following a World Series win at least since 1936, Mr. Peterson said.

On the other hand….

When a World Series lasts six games, the S&P 500 goes on to average a 15.3% gain over the next 12 months no matter which league is victorious, Mr. Peterson says. When the series goes the full seven games, the average return is 8.4%.

Which is not good, but which is not a 38% decline. Go Cards.

    The S&P averages a +28bp return on days when a DB Opening Bell is posted after 9am. In contrast, on days when a DB Opening Bell is posted before 9am, we have no idea how the S&P performs, because we have no such instances to measure.

    So now Jon is blaming the Red Sox for the collapse of the MBS market (which began 12 months before they won the Series–days after the Cardinals won in 2006, in fact) in the US and the Developed World Economy in general.

    It was all (WS MVP) Mike Lowell's fault, not Jimmy "I'm a Pothead Who Plays Bridge, not a CEO" Cayne or Dick "I'm Depressed, You Expect Me to Act Rationally" Fuld or people who thought they could match the returns of Madoff and Steve Cohen through legal means and ridiculous leverage ratios.

    Bess, who graduated from a college in Boston iirc, needs to correct this piece with all deliberate speed.
