Hundreds of thousands of people globally invested in SpaceX's initial public offering, an event that underscored a growing trend: ordinary investors are a significant and expanding force in financial markets, with their emotions often outweighing fundamental metrics. This phenomenon is particularly pronounced in the U.S., where individuals have increasingly embraced speculation as both a means to wealth and an expression of personal beliefs.
Retail investors now constitute over 20% of U.S. stock market activity, a figure that has roughly doubled in the last decade, according to estimates from Jefferies. This surge means individual investors account for nearly as much trading volume as mutual funds, hedge funds, and banks combined, a shift with widespread market implications.
Historical Precedents
The intertwining of identity and speculation in American finance has historical roots, notably in the bond sales that financed the U.S. entry into World War I. Treasury Secretary William McAdoo, facing the immense financial needs of the war, launched the "Liberty Loans" program to mass-market government bonds. At the time, the U.S. government bond market was relatively small, and most Americans were unfamiliar with bonds.
Despite pessimism from Wall Street bankers, McAdoo's campaign was a resounding success. Utilizing rallies, celebrity endorsements like Charlie Chaplin, and sophisticated public relations orchestrated by Edward Bernays, the drives appealed to patriotism and personal aspirations. While some criticized the aggressive sales tactics, including the shaming of "dollar slackers," the Liberty Loans were popular. Buying bonds became a communal act of belonging, with organizers deliberately fostering competition among different groups to demonstrate loyalty. This effort raised $21.4 billion, equivalent to about $9 trillion today, transforming the war into a unifying national endeavor.
The Legacy of Liberty Loans
Though the wartime unity eventually dissolved, the Liberty Loans had a transformative impact on America's investment culture. By the end of the conflict, approximately 34 million Americans had purchased federal bonds, a significant increase from the estimated 350,000 bondholders at the war's outset. Research indicates that areas with higher participation in the Liberty Loan program were more likely to invest in both bonds and stocks in the future. A National Bureau of Economic Research paper estimated that stock ownership would have been 20% lower without the Liberty Loan campaigns.
Modern Markets and Identity Investing
In the contemporary landscape, social media and gamified trading apps have further blurred the lines between investing, speculation, and gambling. Warren Buffett noted in 2023 that markets exhibit more "casino-like behavior" than in his youth, with the "casino now residing in many homes." JPMorgan Chase CEO Jamie Dimon has similarly likened prediction markets to gambling, while acknowledging that "people have been gambling forever."
Political polarization has introduced a new dimension, turning the cohesion fostered by programs like the Liberty Loans into a force that drives Americans apart. For some investors, a company like SpaceX represents an expression of faith in visionary leaders and ambitious goals, with the current stock price being a secondary concern. This trend extends to members of Congress, where stock market activity can function as a venue for identity signaling rather than solely wealth accumulation.
This shift toward identity investing, driven by emotion rather than fundamentals, is seen as a dangerous trend that can accentuate political polarization. While the extent of this phenomenon may fluctuate with market cycles, the deep intertwining of American zeal for speculation and a willingness to let emotions influence decisions suggests these forces may now be inseparable.
