See this clip, at 2:17. Over the longer term, the stock prices should equal the present discounted value of dividends, themselves relective of earnings and profits. That’s basic finance. That being said, there are over time substantial (apparent) deviations from the PDV of dividends (see Shiller, AER 1981), or big moves in the price-earnings ratio, defined in any way you want (12 month trailing, cyclically-adjusted, 1 year forward), as earnings fail to materialize, or the equity risk premium seemingly changes.

Overall, the cyclically adjusted price-earnings (CAPE) ratio is only slightly higher than the 2021M11 level, in the aggregate. On the other hand, the inflation protected 10 year yield is now a full 2.8 percentage points higher than then!

Here are the price-earnings ratios for the Magnificent-7 vs. S&P500 ex-Mag 7.

Does it matter that this particular sector seems, to me at least, potentially overvalued given current real interest rates? Well, perhaps, as current capitalization of Mag-7 is 35.9% of the S&P500.

So time will tell. Personally, I thing the purportedly pro-growth policies (financial deregulation, dilution of capital requirements) alluded to will increase a likelihood of a “discontinuous change” in asset prices (recall, the 2008 financial crisis followed a period of financial regulatory disarmament, as discussed here).
