I really don't like repeating myself endlessly but there are only three requirements to be a real shorter. And I mean a short investor not a short-term-speculator-tax-loss-generator. First is the analysis. Is the market price significantly higher than its real value? Second is: do you have the cash to support your short? You have to have enough cash so that you don't get squeezed out on a margin call. Third and most important: do you have the balls? And that means taking the plunge and initiating a short. And being patient when the price moves significantly above your price. And waiting. And watching. And not closing when you make a minor gain. So there are two questions you need to answer. And if you can't answer them positively then ask yourself why you spend any time doing the analysis? Doing all the work for no gain is not a smart move. It's stupider than doing nothing. So which is it?
