All right, let's treat it as a serious question.From ca. 1967 to ca. 1984, the Dow "appreciates" from around 874 to around 875. (Op. cit. Warren Buffett.)
Let's treat that as the equivalent of the Swiss Franc ca. 1971--an undervalued asset.
We move to floating FX rates under Nixon, and by 1974 Galbraith's daughter (iirc) is saying she wants to be paid in SFR/CHF {pick your abbreviation of choice).
From 1998 to 1999 alone, the DJIA appreciates about 18% (using the monthly numbers), while the lowest investment-grade (BAA) Corporate Bonds are yielding ca. 7.25-7.50%, and 10-year Treasuries are running 5.5% at the beginning of the year and close to 4.5% at the end.
So even if we're assuming a ca. 4% standard Equity Premium--ignoring transaction costs, as well as some regulatory restrictions on USTs that may distort a lot of the data, as per Mehra and Prescott, Epstein and Zin, et seq.--we're looking at a situation in the late 1990s that is closer to the 1971 USD than the 1971 CHF.
Not, in short, a situation where "three to five years" is likely to produce a near-trebling of the Dow. (By your own Equity Premium, that would require Treasury rates running ca. 50% in the longest case [5-year] scenario.)
If the 4% EP holds--not the way I would bet, but your mileage clearly varies--and the U.S. grows at 3% with no inflation, we would see 36,000 from the current levels around March of 2034.
Those of us who describe the Equity Premium Puzzle as the Phillips Curve of Neoclassical Economists will take the Over, thank you, recalling Robert Heinlein's old dictum: TANSTAAFL.
