Quote from inandlong:
Knowing the fundamentals is one thing, basing your intraday entry and exit decisions on them is another.
I doubt you teach your traders to jump in when the P/e gets to 18.1 and get out when it is 18.5. I am sure you don't send a quick note to your guys and say, "Hey, GE just bought another imaging company, let's ride this baby for a quick 20 cents."
This is what I liked about a CANSLIM approach; even if one applied only the most basic filters, the number of tradeable stocks dropped from thousands to only a few hundred. And it wasn't all that difficult to reduce that to a few dozen. And guess where the volume turned out to be?
But once the universe is defined, continuing to make the fundamentals a factor can kill you (it's a good stock; it'll come back). At that point, TA rules.
