Bottom fishing is a popular investor pastime, but it’s usually the fisherman who gets hooked. Trying to catch the bottom on a falling stock is like trying to catch a falling knife. It’s normally a good idea to wait until the knife hits the ground and sticks, then vibrates for a while and settles down before you try to grab it. Grabbing a rapidly falling stock results in painful surprises, because inevitably you grab it in the wrong place.
