In every single crash I know of there were lots of naysayers up until the actual crash. As a matter of fact, right after each crash I personally remember, there were some of those naysayers who got elevated to oracle-status by the press for a time, "the one who had foreseen this all". But they always failed to predict the timing of the next crash, so oracle-status didn't last. Bottom line: still having naysayers isn't a relevant signal. Predicting that there will be a crash is easy (you are almost guaranteed to be eventually right). Predicting WHEN the crash will be is (almost?) impossible.
