Sure, we're all fades from time to time. But after running this board for 18 years (almost to the day), I've found that this crew is, for the most part, really pretty good.
That's why I don't look for tops unless there are a lot of Short Bears in the polls, nor bottoms unless there are a lot of Long Bulls.
Similarly, when we are really leaning hard long (4:1 FL:FS, but less than infinity), it's a "Tipping Point" Buy. I think that when so many of us are confidently long, there is a reason, or rather there are several very good reasons to be long. It's a good signal anyway.
