‘Good luck! We’ll all need it’: U.S. market approaches end of ‘superbubble,’ says Jeremy Grantham

“One of the main reasons I deplore superbubbles — and resent the Fed and other financial authorities for allowing and facilitating them — is the underrecognized damage that bubbles cause as they deflate,” said Grantham.

The Federal Reserve doesn’t seem to “get” asset bubbles, said Grantham, pointing to the “ineffably massive stimulus for COVID” (some of which he said was necessary) that followed stimulus to recover from the bust of the 2006 housing bubble. “The only ‘lesson’ that the economic establishment appears to have learned from the rubble of 2009 is that we didn’t address it with enough stimulus,” he said. 

Equity bubbles tend to begin to deflate from the riskiest parts of the market first — as the one that Grantham is warning about has been doing since February 2021, according to his paper. “So, good luck!” he wrote. “We’ll all need it.”

While the S&P 500 index SPX, -1.10% and Dow Jones Industrial Average DJIA, -0.89% each notched all-time closing peaks in early January, they’ve since fallen into a slump, along with the Nasdaq Composite Index COMP, -1.30%, as investors anticipate the Fed will end quantitative easing and begin raising interest rates to combat high inflation later this year.

The technology-laden Nasdaq has seen the biggest decline among the three major stock benchmarks in 2022, tumbling into correction territory after reaching a record high in November, according to FactSet data. 

“We are in what I think of as the vampire phase of the bull market, where you throw everything you have at it,” Grantham wrote. “You stab it with COVID, you shoot it with the end of QE and the promise of higher rates, and you poison it with unexpected inflation – which has always killed P/E ratios before, but quite uniquely, not this time yet – and still the creature flies.”

That is “until, just as you’re beginning to think the thing is completely immortal, it finally, and perhaps a little anticlimactically, keels over and dies,” said Grantham. “The sooner the better for everyone.”

The Nasdaq has dropped 9.5% this month, through Thursday, exceeding the S&P 500’s nearly 6% slide and a 4.5% loss for the Dow, according to FactSet data.

As for GMO’s investment recommendations, Grantham summarized them as avoiding U.S. equities while emphasizing value stocks in emerging markets and cheaper developed countries, “most notably Japan.” On a personal note, he said, “I also like some cash for flexibility, some resources for inflation protection, as well as a little gold GC00, -0.43% and silver.”

Beyond the recent record highs of the U.S. stock market and “crazy” investor behavior that has accompanied its rise, Grantham warned that “we are indeed participating in the broadest and most extreme global real-estate bubble in history.” He said that houses in the U.S. are at “the highest multiple of family income ever, after a record 20% gain last year.”  

Plus, said Grantham, “we also have the highest-priced bond markets in the U.S. and most other countries around the world, and the lowest rates, of course, that go with them, that human history has ever seen.”

And then there’s the “incipient bubble in commodities,” he added. Oil CL00, -1.78% and most of the “important metals” are among commodities priced broadly “above trend,” while the “U.N.’s index of global food prices is around its all-time high,” according to his paper.

“The combination, which we saw in 2008, of still-rising commodity prices with a deflating asset price bubble is the ultimate pincer attack on the economy and is all but guaranteed to lead to major economic pain,” he wrote. 

Grantham also considered how wealth compounds more slowly at “bubble pricing,” while making it hard for people to afford their first house or to build an investment portfolio. 

“There is the terrible increase in inequality that goes with higher prices of assets, which many simply do not own, and ‘many’ applies these days up to the median family or beyond,” he wrote. “They have been let down, know it, and increasingly (and understandably) resent it. And it absolutely hurts our economy.”
