It's a given that stocks must rise while the Fed is meeting. I think there was a study recently showing something like 80% of all stock gains in the last decade or so have been during Fed meetings. Yesterday's stats of how it was accomplished are quite shocking though. The S&P500 was up 1%, however the advance decline ratio was only 25.8%.  Going back to 1965, tracking 6,702 days where the S&P closed up, yesterday was the 3rd worst advance decline ratio in 50 years.
