I'd be interested to hear the logic of whoever voted "NO" here. Average PE ratio is around 25:1 and the only way for that to make sense is for the stock price to keep rising or for average American companies to suddenly become hugely more profitable. Lemmings.

I agree it’s expensive based on historical PE ratios. The wildcard is AI. If it produces a step-change in productivity and earnings, today’s valuations could prove rational. I think there's a real chance of that.
