i'm starting a new trend: ask every person that is so certain about the negative outlook how big their short position is. so how big is your short position? please let us know.
That's a dishonest argument. For a short to work, you need to be right about the direction _and_ the timing. Being right too soon amounts to being wrong, and the market can stay irrational longer than you can stay solvent.
This is more mantra - professional shorts exist and they make money. So either you know something (in which case you'd be mum about it and just placing your bets) or you know nothing.
