Market Capitalization: Don’t Ask The Barber If You Need A Haircut by Christopher Pavese, The View from the Blue Ridge

The bulls are quick to site a dozen or so reasons why the ratio of Market Capitalization to GDP is not an effective valuation indicator – the economy has evolved over time; an increasing share of earnings are sourced from abroad; the components of the S&P have changed dramatically over the years; blah, blah, blah.

At the end of the day, the unfortunate truth is that the folks who take issue with this particular valuation yardstick are the same folks who benefit from telling investors to expect continued double-digit returns from stocks. Don’t ask a barber if you need a haircut.
