No, it shouldn't. And no it didn't.
Stocks going back to 1926 have had dividends account for about 40% of the total return when one reinvests the dividend. But that encompasses DECADES of high-yields for the DJIA and S&P 500 (the DJIA yielded 10% in 1932). Not until 1956 did the yield on stocks fall below that of bonds -- beause most investors had long memories and remembered stocks going down 85-90% from 1929-32.
Stocks have been de-risked because information is more easily accessible on corporate fundamentals. In the 1880's, information on railroad stocks sometimes took hours or days to reach investors. In the 1920's, information still took a few minutes, sometimes an hour or so. Today, information takes seconds or less.
Yields are less important to total return compared to growth. And I say that as a dividend and value investor.
But you are eliminating a huge change from 1982: the ability to buy back stock. Before then, companies either hoarded cash or paid dividends. Today, they can buy back stock and many companies prefer to do this. You have to compare shareholder yield (dividend yield + stock buyback yield) to have a valid number.
In the old days, the DJIA would be a buy at a 6% dividend yield and a sell at a 3% dividend yield. But that encompassed a RISING rate environment from 1946-81. We've had a FALLING rate environment for decades and even with the latest rise we are still historically low in yields.
Net-Net: yields are not going back to the old levels on stocks because today's stocks are less-risky, more transparent, and in many respects CHEAPER with more defensive MOATS than their predecessors.
Compare today's Tech Titans to the 1970's "Nifty Fifty" stocks. No comparision in terms of market dominance and ability to adapt.
