dude, market is programed to go up. short at your peril. future is impossible to predict, we all know that. so buy dips, but never short. if market goes down, just buy dips, you will be rewarded in the future.
I have been buying the dips too and made a $hitload of money doing it. I am not short SPY, shorting is only for fools who use margin, I refuse to use it. I will only buy puts so my maximum risk is the premium I pay. Stocks can theoretically go to infinity so shorting in an uptrend is a fools game. My puts are for April so there will be a pullback well before then, but it could be severe weeks away, so short at your own peril.
