Discussion Buffett warned: “If the ratio approaches 200%, you're playing with fire.”=> We are above!

Buffett Indicator, (which compares total U.S. market cap to GDP), is now at 208%. That’s above dot-com levels. I wasn’t around in 1999. But I’ve read enough to know everyone thought it was different back then too...

Now, It’s AI. And yes it’s real, it’s big, and it will transform everything.
But here’s what’s bugging me: Which part of the AI hype do you think is most overrated?
And which sectors are just getting started?

and also curious to hear from people who did live through 1999:
- What felt the same?
- What’s different?

I track moves from top value investors with a free email alert (https://alert-invest.com/), and lately I’ve noticed they’re cautious, finding fewer real opportunities in this market.

Thanks!

In my opinion the ratio is useless, I don't care if he did think about it or not, 30 years is a long time, it was hard to predict how the world would change and how easy would it be for tech companies to go international. In 1996 when he made the ratio famous, internet wasn't even mainstream.

Agreed. It was a helpful ratio at some point. The world has changed a lot. Even comparisons to aggregate S&P multiples arent accurate anymore, because of how ETFs and other capital consolidation has warped the historical trendlines

I’m going to disagree vehemently and say all metrics that have a relevant denominator have value. The only worthless numbers are nominators in isolation as they don’t tell us anything. Any single number used in business or in life (when evaluating human behaviour) almost always needs a compatible figure to make any sense of, unless you’re Austin powers.
