I was in, not out yet, ha ha I am proponent of efficent market. I dont think there is any arbitrage opportunity in the world out there. Do some analyticals and determine if they are growth stcosk. and if they grow at the same rate that you think of, ofcourse they will go up. Why dont other investors get those growth stocks then? because there are millions of companies to invest and they do. They invest the same way you do. I dont believe that any stocks out there are undervalued or overvalued. Their prices show the fundamentals of those companies. Get one that you think has sound management practices and will work on shareholders behalf on long run.
