In theory, yes, but in practice market premiums are variable and greater than book values. It is true that dividend paying stocks fall somewhat on their ex-date. If they're undergoing capital appreciation too, that's generally made up for in short order.

I'm not saying to disregard dividends in terms of total return, either, only that Buffett wasn't talking about total return, so the "well, actually" I was responding to was just off the mark. If you or me were alive then and/or aware enough to watch the DJIA (classically in the 20th century, many American's measure of "the market" even if not technically the case) things really would have looked like they went nowhere (nominally) from the middle 60s until the early 80s.
