Several classes of shares are not historically overvalued (based on CAPE ratios, PE ratios, etc.).
These include non-tech US shares, European shares, UK shares and more.
If the (supposedly) overvalued AI-related shares crash, will these other classes necessarily follow them? It is difficult to imagine a scenario in which this does not happen.
If the not-too-overvalued shares do crash, will they recover more quickly?
I know nobody has the answer, but just interested in what people here think about this.
