MoneyShow Chart of the Day 11/06/2025: How Worried Should You REALLY be About this Chart?

Take a look at the chart and you might think…a lot. It shows the “Cyclically Adjusted Price-to-Earnings” ratio from Nobel Prize winning economist Robert Shiller.

The reading climbed to 40.5 in October. Not only is that up from 37.3 a year earlier, but it’s very close to the all-time high of 44.1 in December 1999. Yes, that was just before the Dot-Com Bubble popped.

Google Trends shows the search term “Overvalued Market” is EXTREMELY popular right now in the US, too. In fact, it was the most popular on record in October as you can see in this bonus chart (the data goes back to 2004).

back then, are you really better off for it? Not in the long term (and often not in the short term, either).

If you’re worried about overvaluation and exuberance in the AI space, guess what? You can invest elsewhere! There are plenty of sectors and stocks to choose from.

And if you’re an aggressive momentum-based trader, you may want to just keep buying pullbacks and keep stops tight. At least until “overvaluation” goes from being something to talk about over a cocktail to a bull-killing catalyst.
