Bowling-stock bubble

The Bowling-stock bubble was a short-lived investment boom built on the genuine expansion of American bowling, but driven beyond that foundation by projections that the sport would keep growing at the same pace. Between 1957 and 1958, shares in AMF and Brunswick doubled; by 1963, bowling stocks had fallen 80 percent from their highs. The episode exposes the gap between a real innovation and the market’s imagined future for it: automatic pinsetters helped transform bowling, yet investors poured money into an industry that overbuilt in anticipation of demand that never arrived.

An invention and an expanding industry

The boom’s material origins lay in Gottfried Schmidt’s effort to solve a practical problem at the bowling alley. In 1936, frustrated that there was no one to set pins when he wanted to bowl after work, Schmidt imagined a machine that could do the job quickly and efficiently. He assembled a small team—including car mechanics and another engineer—and built a working model in a turkey coop behind his house, using scrap metal, bicycle chains, and used auto parts. Within a year he had a model and a patent, but no way to manufacture the device at scale.

Morehead Patterson, a vice president at American Machine and Foundry (AMF), recognized the invention’s commercial possibilities. AMF made machinery for the bakery and tobacco industries and was looking to diversify. Bowling alleys still relied on pin boys, which limited how many lanes they could operate; the relationship between pin boys and customers could also be contentious. Patterson saw mechanization as a way to make the alleys more efficient and support their expansion. He went to Pearl River, found Schmidt in the turkey coop, offered him a job, and secured AMF’s control of the patent.

World War II delayed the machine’s arrival: AMF’s factories spent the first half of the 1940s producing war matériel. The pinsetter made its first official appearance in 1946, though it still had problems to resolve. Its commercial breakthrough came in 1951, when a bowling alley in Mount Clemens, Michigan, introduced the first automatic pinsetter. The machines worked faster and more reliably than pin boys, helping bowling become quicker and more pleasurable. Alleys changed from dingy holes into polished destinations, promoting the sport as suitable for the whole family and acquiring the name “the people’s country club.” By the late 1950s, more than 10 million people bowled at least once a week.

From bowling’s popularity to stock-market enthusiasm

The sport’s growth gave investors an observable success on which to build larger expectations. From 1957 to 1958, AMF and Brunswick shares doubled. Smaller bowling companies went public, and money flowed into bowling-related ventures; alleys opened across the country. By 1960, the United States had 12,000 alleys and 110,000 lanes, while investors had put a total of $2 billion into the bowling business. The investment boom thus had a tangible counterpart: new machines, expanding venues, and a large and growing audience.

Wall Street’s forecasts, however, projected the recent surge into the future as if it could continue at the same rate. Analysts argued that eventually every American would bowl two hours a week. Charles Schwab, then beginning his career on Wall Street, illustrated the scale of the projection by multiplying 180 million people by two hours a week and 52 weeks a year. The calculation made the imagined market sound immense, but its persuasive arithmetic did not establish that the sport would achieve that level of participation. As enthusiasm spread, investment in bowling-related ideas began to feed on itself, becoming less dependent on evidence of lasting demand.

Collapse and misdirected capital

By 1963, bowling stocks had fallen 80 percent from their all-time highs, and it took nearly a decade for them to regain that lost ground. Bowling itself became less popular over time and never again reached the popularity it had enjoyed during the Eisenhower years. The scale of the later contraction sharpened the contrast with the boom: the country eventually had about half as many bowling alleys as it had forty years earlier, despite having about 100 million more people.

The bubble’s damage was not limited to investors’ changing share prices. A stock market directs capital toward companies: firms with high share prices can raise more money by selling stock or issuing bonds. In the bowling boom, investors supplied the industry with more capital than the evidence justified, and bowling companies did not use all the money wisely. They overbuilt and overinvested for a future that failed to materialize. The distinction matters: the pinsetter had helped make bowling more accessible and popular, but the invention’s success did not warrant every forecast or investment built upon it.

What the bubble reveals about collective judgment

The episode illustrates how collective decision-making can fail when the conditions that support sound group judgment—independent opinions, diversity, and private assessment—give way to shared enthusiasm. Rising prices became part of the attraction, while forecasts treated recent popularity as a promise of continued growth. In that feedback loop, market activity did not simply measure expectations; it helped amplify them and channel resources toward an industry whose future had been overstated.

The book places the bowling boom among sector-specific bubbles, alongside episodes of investor enthusiasm for uranium, conglomerates, recreational vehicles, personal-computer companies, and biotechnology. Such manias differ from rare bubbles that sweep up investors broadly, but both make visible the risks of prices losing connection with underlying value. Bowling’s boom and reversal therefore provide a concrete case of a broader problem: when a crowd mistakes shared confidence for independent confirmation, substantial capital can follow an imagined future instead of a sustainable one.
