As an add on to the previous post about trying to profit from peaks and valleys by shorting, and JD's excellent feedback: You could accomplish the same thing if you are long on CRA (which you state you are), buy buying what you predict are the valleys with your "play money" and sell those shares at what you think are the peaks (not short-sell). Do it with money you did not intend on having ltbh. The worse that could happen, if your a believer in the company long term is hold longer than originally ancticipated. I wouldn't recommend it but if you have these urges it is safer than shorting. This lets you gamble with at least a better back up plan. And is congruent with your view of this company's long term potential.
