This combination of valuation + volatility has only been seen a few other times

Jason Goepfert
2021-04-21
The ratio of the S&P 500's price / earnings multiple and the VIX "fear gauge" has rarely been higher.

Investors are pushing the valuation of stocks to extreme heights, and not even having to suffer much volatility along the way. That started to change in a minor way over the last 2 sessions, so we'll have to see if it lasts.

One of the ways we've looked at a shorthand for sentiment over the years is by comparing the S&P 500's forward price/earnings multiple to the VIX "fear gauge." The higher the ratio, the more investors are getting away with pushing valuations higher without much of a consequence.

A 10-day average of the spread between those two factors just reached its highest level in a year. 

S&P 500 price earnings multiple relative to VIX

Zooming out over the past 30 years, the current spread is still among the highest readings. After other extremes, the S&P 500 itself declined every time but once, while its valuation declined every time and volatility did the opposite.

This has now been added as a premium chart for daily updates and backtesting for users.

Stat Box

With 138 securities falling to 52-week lows and only 68 rising to 52-week highs on Tuesday, so soon after the Nasdaq 100 had been at a record high, a Titanic Syndrome technical warning was signaled. This is the 1st one since last September.


What else we're looking at

  • Full history of the PE / VIX ratio
  • What happened to the S&P, its valuation, and volatility after similar extremes
  • An update to our Relative Ratio risk model, which appears on the cusp of a signal
  • A useful long-term clue on when to switch from stocks to gold

Users should conduct their own due diligence and consider their individual circumstances before making any financial decisions. Past performance is not necessarily indicative of future results.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
