He used 6 dates:

Oct. 3, 2008 - Rachel Getting Married opens: BRK.A up .44% Jan. 5, 2009 - Bride Wars opens: BRK.A up 2.61% Feb. 8, 2010 - Valentine's Day opens: BRK.A up 1.01% March 5, 2010 - Alice in Wonderland opens: BRK.A up .74% Nov. 24, 2010 - Love and Other Drugs opens: BRK.A up 1.62% Nov. 29, 2010 - Anne announced as co-host of the Oscars: BRK.A up .25%

I'm not a statistician, but 6 dates could hardly be considered a correlation. I would also think that no Anne Hathaway news should result in no positive price changes for a correlation to exist.

Seems like the article confuses correlation with "funny coincidence".

And it certainly doesn't "drive" the stock, as the headline states. That implies a causation, which is even stronger than a correlation.
