So the theory is that there's three groups of people:
It seems to me that you're assuming that a lot of smart investors, with a lot of money, all think that they're going to be the ones who can time the market perfectly before the big crash. To me that seems to be a pretty dumb/risky bet to make. Of course, you also seem to be assuming that they're smarter than the bears because they're going to profit on the way up and the way down. While a lot of bears have been taking huge hits holding short positions, and tons of them have had to close out at big losses.
If you have a short position I can see why you'd be so negative all the time. I can imagine that the truth of the quote "The market can remain irrational longer than you can remain solvent" is starting to sting. Or, if you don't have a short position, you're not really a "bear", you're just someone with an opinion.
