The reason may not be from the company but from the market. Sometimes the market just generates an increase in the price. We've seen it many times if you've been around long enough. Take the internet fiasco a few years ago when buying just drove the price up even on blue chips. Well I seriously don't think that is happening but on individual stocks it still does. It's just that no matter how you look at the market its always one buyer against another. One wins and one loses.
