Some arithmetic on today’s “highly advanced equity bubble”

Yes Virginia, don’t let the salesmen assure you otherwise, we have a massive equity bubble on our hands today. Govern your savings accordingly. See John Hussman’s excellent weekly: Yes, this is an equity bubble, for some simple facts on today’s flashing red risk warnings:

“My sense is that investors have indeed abandoned basic arithmetic here, and are instead engaging in a sort of loose thinking called “hyperbolic discounting” – the willingness to impatiently accept very small payoffs today in preference to larger rewards that could otherwise be obtained by being patient. While a number of studies have demonstrated that hyperbolic discounting is often a good description of how human beings behave in many situations, it invariably results in terrible investment decisions, particularly for long-term investors. As one economist put it, “they make choices today that their future self would prefer not to have made.” In effect, zero interest rates have made investors willing to accept any risk, no matter how extreme, in order to avoid the discomfort of getting nothing in the moment…

Make no mistake – this is an equity bubble, and a highly advanced one. On the most historically reliable measures, it is easily beyond 1972 and 1987, beyond 1929 and 2007, and is now within about 15% of the 2000 extreme.

The main difference between the current episode and that of 2000 is that the 2000 bubble was strikingly obvious in technology, whereas the present one is diffused across all sectors in a way that makes valuations for most stocks actually worse than in 2000. The median price/revenue ratio of S&P 500 components is already far above the 2000 level, and the average across S&P 500 components is nearly the same as in 2000. The extent of this bubble is also partially obscured by record high profit margins that make P/E ratios on single-year measures seem less extreme (though the forward operating P/E of the S&P 500 is already beyond its 2007 peak even without accounting for margins)…

Remember how these things unwound after 1929 (even before the add-on policy mistakes that created the Depression), 1972, 1987, 2000 and 2007 – all market peaks that uniquely shared the same extreme overvalued, overbought, overbullish syndromes that have been sustained even longer in the present half-cycle. These speculative episodes don’t unwind slowly once risk perceptions change. The shift in risk perceptions is often accompanied by deteriorating market internals and widening credit spreads slightly before the major indices are in full retreat, but not always. Sometimes the shift comes in response to an unexpected shock, and other times for no apparent reason at all. Ultimately though, investors treat risky assets as risky assets. At that point, investors become increasingly eager to hold truly risk-free securities regardless of their yield. That’s when the music stops.”
