When Will S&P 500 Valuations Matter Again?

 | Aug 30, 2018 12:41AM ET

In the private markets, buyers and sellers care a great deal about valuation. For example, a financial advisory practice might fetch between 1 percent and 2 percent of assets under management. Or it might go for 2.3 times trailing 12 months’ gross revenues. Higher or lower valuations depend largely on things like key personnel, average account size, client retention, economies of scale and the growth rate.

The critical importance of valuation also comes to light on the popular television show, “Shark Tank.” Having already placed a value on their respective companies, entrepreneurs approach business titans to pitch their products and services. An entrepreneur may want $500,000 for a 25% stake, implying that he/she believes that the company is worth $2 million. Personalities like Mark Cuban and Kevin O’Leary (a.k.a. “sharks”) might not agree. Perhaps one of them might offer $325,000 for a 50% stake, placing the value at $650,000.

In the public marketplace, buyers should care about the price they are paying for S&P 500 corporations. At this moment in time, though, they care little about the price they are paying.

On virtually any methodology one employs, the U.S. stock market is extremely overpriced. Other than the tech bubble’s brief insanity in early 2000, one would be hard-pressed to find circumstances when stock prices were more euphoric than right now in 2018.
