I don't recall that, per se, but, yeah, I agree, and it is pretty standard theory. Assuming that corporate profits stay near a constant proportion of domestic GDP, then those profits grow at roughly the rate of GDP. Then you are back to the Gordon model aggregated up to the level of the entire market, and the expected return is the initial dividend + forecasted GDP growth. Unfortunately, in real life, the stock market is generally in a state of net share issuance, so over time not all of the dividend growth accrues to the original shareholders (they get diluted)...
classic bernstein. But ignoring that dilution, if you also assume that the dividend payout ratio stays reasonably stable, and the P/Div ratio stays reasonably stable, over long periods of time, this is basically what you expect. And there are no long-term workarounds.
Now, as to the real GDP growth assumptions - No problemo! We are very smart monkeys, and we have got the
grow, grow!, grow!! thang all figured out.
For example, just look at the kick-ass job we are doing as we expand our dominion across the oceans! A little bit more growth, and who knows what we can accomplish!!! Go, homo sapiens, go! Best fishes, parvus!
