i'm not saying you should be a super skeptic permabear, not at all. i have seen averages climb too high, watched the market make people too much money to be that cynical and closed-minded. being negative has not been a lucrative strategy. i don't see a reason that should change now. there are professional short sellers out there. hats off to them. they have turned pessimism into profits but i don't recommend trying to follow them at home. uh never recommend short selling. out's more risky than being long. it's just a basic question of arithmetic. when you short a stock or bet against it at best the stock goes to zero and you have 100% gain. at worst it could never stop going higher. you could lose 200, 300, 1,000%. you could lose infinite money if you're short. when you own a stock the most you can lose is 100% of your money but you can quintuple your investment. ask anybody who bought apple near the generational bottom in march of 2009 when it pulled back to less than a hundred bucks. over the next five years they scored a 580% return.
