I thought you would have seen my recent updates for those(I can't remember who asked) interested in a really simple way to trade in and out of a stock. It does get you whipsawed quite often, but it is a small price(literally) to pay for keeping most of your moolah.
It is simply to trade out of the stock as the PPS crosses down over the 28 day SMA and to buy the stock when the PPS crosses back up over the 28 day SMA, on a 3 month chart. Would have gotten you out about 34.70 in Sept and whipsawed you last week. You'd be waiting right now to get in again for the run. Try it SeaD! Back test it on your favorite stock. Don't ever say ole Doc wasn't there for you...;-)
Ahhhh, the 28 day sma!!!! Of course. Of course. Everyone knows that. Makes perfect logic and infinite sense. But, why not the 27.12567459 day sma minus 3 toadal warts plus 5 persian cat hairs tied end-to-end ? :)
