CAPE Ratio Tops 40 for Only the Second Time in History

The S&P 500's CAPE valuation has climbed to about 41, a level exceeded only once before during the dot-com bubble, prompting analysts to urge selectivity.

The stock market has entered one of the most expensive stretches in Wall Street history, with the CAPE ratio reaching its second-highest reading ever at about 41. The metric, which averages the last decade of S&P 500 earnings to smooth out recessions and abnormal swings, has exceeded 40 only once before: during the late-1990s dot-com era, when it peaked at 44. Motley Fool analyst Steven Porrello, whose syndicated analysis appeared in The Globe and Mail and AOL, argues this is not a doom-and-gloom signal but a reminder that investors are paying a historically high price to access long-term equity gains.

A high CAPE does not mean a market crash or recession is imminent, and treating it that way is a common mistake that confuses correlation with causation. More likely, the reading signals that investors expect massive growth from S&P 500 companies. The danger is asymmetric: if earnings growth fails to arrive as large as expected, disappointment could lead to the kind of crash seen in 1929 or 2000, but there is no guarantee of that outcome. Syndicated coverage in AOL also notes that today's market differs from past eras, because app-based, commission-free trading has made stocks accessible to far more investors, which could support valuations that historically looked high.

The valuation pressure is compounded by an unusually demanding bond backdrop. TechStock² reports that the 10-year Treasury par yield closed at 4.96% on Friday, September 11, near its highest level since 2007, after climbing roughly a percentage point since late February. Inverting that yield produces a roughly 20.2-times multiple of annual return — not a fair-value price-to-earnings target, since Treasuries carry a fixed contractual return while stocks offer uncertain but potentially growing cash flows, but a useful scale check. Equities trading above that hurdle need growth, durability or capital returns strong enough to compensate for much greater risk.

Separate historical analysis from The Motley Fool suggests that selling into weakness has been the costlier mistake. Since 1985, the S&P 500 has returned a median of 17% in the 12 months following its first close in bear market territory, and a median of 16% after its first close in correction territory, per the outlet. The Nasdaq Composite has been even stronger, with a median 12-month return of 40% after its first bear-market close. The same analysis notes both indices have always recouped their losses, and that over the past decade the S&P 500 gained 325% and the Nasdaq 460% despite frequent corrections.

TechStock² notes the Nasdaq is especially sensitive to a bond selloff, because more of a growth company's estimated value sits in profits expected years from now, so a higher discount rate has a larger present-value effect. August consumer prices rose 0.4% from July and 3.4% year over year, per Bureau of Labor Statistics data cited by TechStock², leaving the Fed confronting hotter headline inflation even as core inflation cooled to 0.3% monthly and 2.4% annually.

The Federal Open Market Committee begins its two-day meeting on Tuesday, September 15, and releases its policy statement at 2 p.m. ET Wednesday, September 16, followed by the chair's press conference at 2:30 p.m. ET, according to TechStock². The statement's treatment of inflation and future moves may matter as much as the immediate rate decision, particularly after three members dissented in favor of a hike at the July meeting. The reported recommendation for investors is discipline rather than panic: favor companies with strong balance sheets and durable earnings, keep diversifying outside the most expensive sectors, and keep investing, since any valuation pullback could put great stocks on sale.
