One thing that surprises me is that we have basically all the textbook signs of a bubble: very high PE, PS, CAPE, debt load, Value under-performing growth, extreme enthusiasm for a particular group of companies (tech), old-fashioned value investors either throwing in the towel or converting (BRK bought Amazon), nonsensical public manias (Bitcoin), a plethora of unprofitable IPOs doing great, all time low unemployement........
But even though I do see some hubris here and there, I do not see euphoria or even as much as a healthy good old fashioned dose of optimism (except from Buffett but he's completely waterproof to herd psychology). Neither among investors, CEOs, journalists, on TV or among friends and family. Instead, I hear utter FEAR and a certain type of cynical resignation to the idea the whole world is soon going to hell (political polarization, climate change, fake news, education quality, pollution, nationalism, children being less well-off than parents, the end of our shared belief in truth, in science, in common decency, upcoming "unavoidable" wars...).

So who are all those optimistic people pushing the sp500 higher and investing in Beyond Meat and stuff??? Where are they hiding?
