Sentiment more bullish than the previous 2007 top

Right before the major collapse in the stock markets of late 2007, the sentiment hit an extreme level of bullishness, even with mortgage institutions collapsing into bankruptcy and the real estate market imploding because of the US lemmings falling under the weight of the debt they couldn't possibly service.

So we may very much have reached a top, at least a cyclical one, even though the fundamentals should suggest a secular one. I already mentioned this last week (Apogee of exuberance, paroxysm of irrationality. Sign of a top?), and it's been confirmed for now but here are some impressive charts to back that up.

[Update: I hadn't seen this one, but even Lehman Brothers shares surged in the last several days, and went from $0.05 to an intraday high of $0.32, which is about +650% in one day.]
