So if it can do anything, and you don't care what anyone says... aint it gambling?
notice I did not say every stategist... in fact, in the short term, most of the fundamentals persons are wrong, just like many oil and gas execs I know myself. Where they are helpful is in the long term.
In the short term, while yes, no one knows 100%, there are signs as to what is going on, and many investments follow their past trading pretty well.
But just because something is cheap or oversold, does not mean it can't go even lower. Heck, I have plenty of BBRY shares to prove it.
