Correct. I agree that it is not too late to buy. Just be careful that if you trade the swings, you will never get rich. The big boys will pull your strings like a puppet. Better to know the stock deeply and if there is sign off trouble (none of that with SDL)the you sell. The trick is to be a Turtle Trader - buy a great investment. You can still trade the swings and many do that - but you can be certain that you will miss the big game.
