Barry Ritholtz dismisses talk of a bubble (2021)

I think we have to be careful about painting with too broad a brush when we talk about sentiment.  I can't ever recall in history where market bubbles were called so fervently and frequently in real time by participants, but we've been hearing people saying "this is a bubble" now since - I don't know, is it five years?  Certainly off the lows last year the bubble drumbeat started.  It's kind of hard to see markets being overly optimistic when there's so much fear on valuation and bubbles.  I know it's very counterintuitive, but it's just not what you typically see when everybody throws caution to the wind and they're all in.
