One thing I am not sure is "buy on rumors, sell on news". Once wathced a stock, up a lot in one month (guess people were buying on rumors), down 2% on the ER day before the release, after the earning release declaring good profit beating wall street expectation, jumped up by 10%. why did people not sell on news?
