Could the Dow drop 50%?

"Two views make a market," goes the adage, so there's no "right" value for the Dow. But as I showed yesterday, the Dow has had an extraordinary rise in the last 20 years, about double what has happened with the FTSE.

It doesn't seem related to average income (American average earnings have grown more slowly than in the UK); if it relates to greater inequality of income, then presumably if the market turns, rich bears will be capable of pushing it down as fast as it rose. And I doubt that American multinationals have exploited subsidiaries in the Far East that much more than British-based multinationals - or have they?

Or is it money invested through the carry trade, borrowing cheaply from Japan? Then maybe it will unwind when Japanese interest rates rise. Is it the benefit of low American interest rates, thanks to huge foreign support for US Treasury securities? That love affair is coming to an end.

Let's do a thought experiment. 1987 seems a reasonable base year for our measurements, since the markets weathered the "Crash" of October and still ended up ahead by the end. From the end of 1986 to close of business this last Wednesday, the FTSE had grown by some 280%. That works out at around 6.7% capital growth compound per annum, for the whole period; add-in dividends and the reasonable investor should be satisfied.

If the Dow had done exactly the same as the FTSE, it would have grown from 1,895.95 to around 7,200. Instead, it closed on Wednesday last at 13,657.86.

Maybe there's still a lot of air in that balloon.
