Let's all listen to Al then, so we can all sell at the same time and buy at the same time, making swings even worse.... It might go well a few times but in the end you'll end up without any shares when a major upmove occurs, because Al just told you to sell.. And that is what you did ofcourse... Then you start thinking to yourself should i still get in at this higher level? No i'll wait for it to come down again! That never happens ofcourse and soon after we're bought out... Being long means looking to the horizon, not at your shoes, you might stumble.
