I should add the Smithers complains that many people do abuse the dividend discount model by using the wrong discount rate, so I've no doubt that there are any number of examples of people doing so that can be quoted. The only question is how impressive they are as an authority. I wouldn't be that bothered if Buffet did so, but I would be interested if Graham did.
For what it's worth, I've just looked in "The Four Pillars of Investing" by Bernstein, and he says (on pages 50-51) "the DR of the Dow is simply the rate of return we expect from it, taking its risk into consideration." (DR = discount rate.) He goes on to say that if we expect an 8% return from stocks, then 8% is the correct DR. So he agrees with Smithers.
Smithers makes the point that for valuing stock markets, you have to use the expected return on stocks in normal times as the discount rate, not the expected return at the time of the valuation. So (my explanation) if you think stocks generally return 6% real, then you feed 6% into the equation and possibly conclude that from "current" levels (say if you were doing this at the 2000 peak) they will only return 2%.
