The stock market looks increasingly divorced from economic reality.

The United States is on the brink of the worst economic collapse since the Hoover administration. Corporate profits have crumpled. More than 1 million Americans have contracted the coronavirus, and hundreds are dying each day. There is no turnaround in sight.

Yet stocks keep climbing. Even as 20.5 million people lost their jobs in April, the S&P 500 stock index logged its best month in 33 years. After a few weeks of wild swings, the market is down a mere 9.3% this year and 13.5% from its peak (as of the start of this week) — what most investors would consider a correction. On Friday, after the government released the staggering unemployment figures, the S&P 500 closed up 1.7%.

Conventional wisdom would explain the market’s comparatively modest losses this way: Since markets tend to be forward-looking, investors have already accounted for what is expected to be a cataclysmic drop in second-quarter activity and are forecasting a relatively rapid economic recovery afterward. The Federal Reserve’s actions have also bolstered investors’ confidence that the bottom will not fall out of the market.

But the pandemic has also highlighted a deeper trend. For decades, the market has been growing increasingly detached from the mainstream of American life, mirroring broad changes in the economy.

“Wall Street has very little to do with Main Street,” said Joachim Klement, a market analyst at Liberum Capital in London. “And less and less so.”

Still, the market retains its grip on the collective imagination. From politicians and corporate executives to mom-and-pop investors, Americans have long relied on the stock market as a proxy for the U.S. economy — for reasons that are partly historical. Its crests suggested bright days ahead, while its troughs suggested a darkening outlook. The current economic fallout, however, could snap any illusions that the logic of the market is derived, in any consistent way, from real-world events.

Part of the reason is the makeup of the stock market, and the fact that the giant companies that make up the S&P 500 operate under very different circumstances than the nation’s small businesses, workers and cities and states. They are highly profitable, hold significant sums of cash and have regular access to public bond markets. They are far more global than the typical American family firm. (Roughly 40% of the revenues of S&P 500 companies come from abroad.)

In 2015, about 600,000 U.S. businesses counted at least 20 employees, and only 3,600 of those — or less than 1% — were publicly listed, said René Stulz, a professor of finance at Ohio State University, who has studied the changing composition of publicly traded markets.

Because the financial strength of big companies makes them more likely to survive the downturn, their share prices tend to underplay the effect of a widespread economic collapse. In fact, market indexes like the S&P 500 are weighted to reflect the performance of the largest and most profitable companies. In recent weeks, the stocks of such companies have not only veered in the opposite direction of the outlook for the U.S. economy, but from the rest of the stock market itself.

The five largest listed companies — Microsoft, Apple, Amazon, Alphabet and Facebook — have continued to climb this year, as investors bet these behemoths will emerge in an even more dominant position after the crisis. Through the end of April, these companies were up roughly 10% this year, while the 495 other companies in the S&P were down 13%, according to Goldman Sachs analysts. These highly valued firms — Microsoft, Amazon and Apple are each worth more than $1 trillion — now account for one-fifth of the market value of the index, the highest level in 30 years.

“It’s very easy to get confused by looking at the S&P doing well and that being driven by a relatively small subset of firms which aren’t really affected by this virus and actually gain from it,” Stulz said.

Economists who have studied the performance of stock markets over time say there is relatively little evidence that economic growth matters to the outcome of the market at all.

“The linkage is actually pretty weak,” said Jay Ritter, a finance professor at the University of Florida who has studied the long-run relationship between economic growth and market returns in world markets. “In the longer run, the relationship is, empirically, it’s not there.”

None of this is a secret. So why do millions of Americans continue to think the market really is a barometer on the economy? That is more a question of history and culture than economics.

Historians say the stock market’s link in the American psyche to the economic health of the country goes back, at least, to the 1929 crash.

“You can think of the Great Crash as almost traumatizing Americans,” said Janice Traflet, a financial historian at Bucknell University’s Freeman College of Management.

With little quality economic information, many Americans saw the 1929 market collapse — the S&P fell an astounding 86% before bottoming in 1932 — as the event that caused the Great Depression. The close connection between the health of the economy and the health of the markets, in the minds of many Americans, had been forged.

“Whether or not they were right or wrong, that’s the way many Americans interpreted it. And sometimes perceptions become the reality,” Traflet said.
