It is said that the successful trader captures 30% of the movement in s stock's price. It is also an old saying that traders drive Chevrolets while investors drive Cadillacs. Given GM's and the USA's woes I'm sure that statement could be upgraded to more approriate auto models. Nevertheless, waiting for the move is a valid strategy. Trouble is you have to be waiting for all moves in your sector. Try to be nimble, you have my respect and my sympathy.
Simply, buy low, recover your initial investment on big moves and then make choices based on the information available.
I've got a tiger by the tail in KXL, and I'm not going to let go. Yet buyer's should be forewarned, when I buy I'm averaging up, not down.
