the professor mentioned the "January Effect Model" which he says is that by the end of January, if it was an up month in the market, then the general idea is that the whole year will be an up year. Thought that was interesting.
More interesting, he talked about the "Super Bowl Model", where he says that if the NFC team wins the Super Bowl, then it will be a good year, and if the AFC team wins the Super Bowl, it will be a down year. He said while it seems arbitrary and meaningless, it is accurate about 80% of the time.
