@GaryMarcus I don't think price fluctuations within normal sectoral variance are evidence of a bubble

I'd say it was a bubble in retrospect once the entire S&P 500 sells off 20%+

@peterwildeford no matter what happens, you will say it wasn鈥檛 a bubble. 1929? not a bubble; prices went up before they went down. dot com, same thing.

Prices go up: OMG it's a bubble
Prices go down: OMG proof that it was a bubble

what if the bubble were to deflate and nobody wanted to say so out loud?

The conversation involves a debate about the definition and identification of economic bubbles, specifically in relation to stock market fluctuations. The participants discuss whether price changes in specific sectors or the broader S&P 500 index indicate a bubble. The tone is analytical and somewhat skeptical, focusing on economic theory and market behavior.
