Daytraders, and I refer to traders who are flat, holding nothing but cash or equivalents at end of day, regardless of trade style, are THOUGHT TO BE terminators of the flow of money in the given instrument or vehicle. The trade is done, flat, someone has lost money, someone has made money. period. The way the money flow starts again is with fresh trades ideas, maybe different vehicles or instruments, based on different criteria. It doesn't matter if the criteria is dynamic or fundamental, it is different and the trade itself has different expectation and different participants.
Case in point... a retired neighbor friend asked me about VZ in October '07. The stock was above $42. I suggested he place a sell stop order (of course he had no clue what that was) at his breakeven price, taking the dividend he has received into the calculation as well. He did not do it. Right now his account value is down 15% from the October high, and has been down over 20% in recent days.
If I was a daytrader of stock, which I am not;futures only, he would be pretty upset if I told him thanks to VZ and VZ only, I've been living on the lost value of his account for the last 4 months! In his mind, I would have terminated the money flow of HIS investment. Unfortunately, that attitude or more accurately, lack of knowledge, is de facto for the investing public, and is further ingrained by the media.
Gordon Gecko was not a destroyer of companies, he was a liberator of them.
