I felt that catching a falling knife is a very difficult thing to.do. It CAN work sometimes though althouh it's a bit risky since it gets to a point where selling it at that point might not be as good a move as buying when it falls cheap.
Buying into initial sign of strength usually works but buying when it's been on a strong trend can bring undesirable results because then you might be buying at the top. Then again, with a 'certain company', I feel they are always buying at the top. lollll
