<<Fundamentals? Well, simply by loading one's wagon at the right timing (e.g., when hundreds of insiders were buying beaten down bargains in mid 2002, and when 10's or 100's of companies were selling below CASH value, let alone book value) with the right stocks and going to sleep for a couple of months or a year, one can make a killing, as we all know too well. And of course, bailing out at the right time.>>
Short term and daytrading is exactly the same - just on shorter timeframes, and using technical signals rather than fundamental ones. In the end either trade is merely a successful evaluation of supply/demand curves.
