Take a look at several charts, below, that show the magnitude of the stock market’s overvaluation and, more importantly, put it into historical context.
Each chart examines stock market valuation from a slightly differently perspective, but each arrives at the same conclusion: the average stock is overvalued — somewhere between tremendously and enormously. If you don’t know whether “enormously” is greater than “tremendously” or vice versa, don’t worry, I don’t know either. But this is my point exactly: When an asset class is significantly overvalued and continues to get overvalued, quantifying its overvaluation brings little value.
