Warning for next year's performance? Insiders’ stock sales in U.S. equities hit a two-decade high for a single quarter

Recently, the surge in insider stock sales by executives of U.S.-listed companies has drawn media concern. According to a recent Financial Times report, a record number of U.S. corporate executives are selling shares of their own companies—from Goldman Sachs and Tesla to even the media group of President-elect Donald Trump—capitalizing on the post-election rally in U.S. equities. Data from VerityData shows that insider stock sale transactions among U.S. listed companies have reached the highest quarterly level in twenty years. These sales include both one-off profit-taking transactions and scheduled sales triggered when share prices hit pre-set levels under executives’ automated trading plans. The index referenced is the Wilshire 5000—the broadest U.S. equity index by market capitalization weighting—which covers actively traded U.S. stocks. Moreover, in Q4 this year, the ratio of insider sellers to buyers among S&P 500 component companies stood at 23.7:1—the highest since 2004, when the U.S. first mandated public disclosure of insider trading data. large_image?... There are many reasons why corporate insiders sell stock, and most are unrelated to the company’s own prospects. Thus, record insider selling does not necessarily signal an alarming red flag. However, given recent strong returns, elevated valuations, rising leverage, and a broadly speculative market environment, insider selling serves as another warning for U.S. equities overall—suggesting that the market’s performance next year may fall short of expectations. On the link between insider trading and market performance, Ben Silverman, Research Director at VerityData, commented: “In general, insider sales tend to lead market movements by about two to three quarters.”

I have launched an investigation into U.S.-based DuPont. In the context of China-U.S. trade competition, why has DuPont been singled out as a typical case?

III. DuPont’s Past and Present! DuPont—a U.S.-based multinational corporation with over two centuries of history—has evolved from a gunpowder manufacturer into a global leader in science and advanced materials. Its trajectory reflects not only the rise and transformation of a single enterprise but also epitomizes the broader evolution of America’s chemical industry—from traditional manufacturing to high-tech innovation. Below are key phases in its development: 1. Origins and Early Growth (1802–1902) Founding Context: In 1802—during the Jiaqing Emperor’s reign in Qing Dynasty China—French immigrant Éleuthère Irénée du Pont founded DuPont in Wilmington, Delaware, initially producing gunpowder. Government contracts—including those for the War of 1812—fueled early growth. Family-Style Management: For its first century, DuPont operated under strict, quasi-military family control. Henry du Pont consolidated the U.S. gunpowder market through industry alliances and acquisitions; in 1889, he co-founded the American Powder Trade Association, controlling two-thirds of national output. 2. Transformation and Expansion in the 20th Century (1903–2000) The Triumvirate Era: After Eugene du Pont’s death in 1902, the company faced crisis. Brothers Alfred, Coleman, and Pierre du Pont assumed leadership, steering DuPont from a family-run firm toward modern, conglomerate-style management. They acquired or merged with 64 firms, securing control over two-thirds of U.S. explosives capacity, and established E.I. du Pont de Nemours & Company. Diversification and Innovation: During both world wars, DuPont profited enormously from munitions contracts. Post-war, it pivoted decisively into chemicals. Starting in the 1930s, it launched revolutionary materials including nylon and Teflon, cementing its leadership in polymer chemistry. Later innovations—Kevlar, Tyvek—found wide application across defense, aerospace, and healthcare. Management Reform: From the 1940s onward, DuPont gradually introduced professional managers, diluting family control. Subsequent decades saw repeated spin-offs and restructurings to meet global competition. 3. Spin-offs and Restructuring in the 21st Century (2000–2025) As early as 1902, DuPont established multiple laboratories focused on polymer materials—while, at the same time, the Qing court fled to Shaanxi after the Eight-Nation Alliance invasion and signed the Boxer Protocol before returning to Beijing. DuPont’s strategic investment in polymer science thus preceded China’s by roughly 80 years. From 1917, DuPont held a 23% stake in General Motors; by 1920, its 27% ownership gave it de facto control, allowing it to dominate GM’s board until antitrust divestiture in the 1950s. Beginning in 1935, DuPont developed nylon, Teflon, and other breakthrough materials—while China was embroiled in civil war and resistance against Japan. DuPont’s lead here was approximately 70 years. During WWII (1939–1945), DuPont supplied military materials to Boeing and received special equity stakes, shaping Boeing’s long-term decisions on aerospace materials. In the 1960s, the DuPont and Rockefeller families jointly built a chemical-finance conglomerate anchored by Chase Manhattan Bank. From the 1980s onward, DuPont began exiting basic chemicals and petroleum businesses, focusing instead on specialty chemicals and materials science—whereas China’s petrochemical system had only just begun. DuPont’s head start: ~80 years. In 1981, DuPont acquired Continental Oil Company (Conoco) for $8 billion, later leveraging the DuPont-Conoco structure to control 12% of U.S. crude oil production capacity. After 2000, DuPont spun off traditional materials businesses and progressively entered nutrition & health, electronic materials, and medical materials—arriving roughly 20 years ahead of China. In 2004, DuPont sold its textile and interior décor business—including nylon and Lycra brands—to Koch Industries (now Invista) for $4.4 billion in cash. In 2015, DuPont spun off its Teflon and titanium dioxide businesses into Chemours, an independent, publicly traded company. In 2017, DuPont merged with Dow Chemical to form DowDuPont, later split due to antitrust concerns and strategic realignment. In 2019, DowDuPont completed its tripartite spin-off: • Dow—focused on materials science (plastics, coatings, etc.), market cap >$20 billion; • Corteva Agriscience—specializing in agricultural technology (seeds, pesticides), now an independent public company with market cap >$40 billion; • New DuPont—handling specialty products (electronic materials, medical devices), market cap >$25 billion. In 2021, DuPont divested its Nutrition & Biosciences business to International Flavors & Fragrances (IFF) for $7.3 billion. In 2022, DuPont sold the majority of its Mobility & Materials (M&M) division—primarily engineering plastics—to Celanese for $11 billion. In 2023, DuPont sold 80.1% of its Delrin homopolymer POM business to TJC LP for $1.8 billion—representing ~80% of the global homopolymer POM market. In 2024, DuPont announced plans to spin off its electronics business (semiconductor technologies, interconnect solutions) into a standalone public company, targeting completion in 2025. Meanwhile, over the past two decades, China’s domestic chemical materials industry has achieved comprehensive, full-category industrial revival—covering the ground DuPont traversed over eight decades. By mid-2025, China’s high-end materials sector has experienced explosive growth, achieving near-total domestic substitution. The trade conflict has shifted from initial agriculture-focused tariffs to today’s across-the-board 34% blanket tariffs—highlighting the extraordinary intensity and significance of China’s five-year technological sprint. Setting aside national boundaries, while China’s chemical and materials industry has made rapid progress over the past two decades, it still needs to draw on DuPont’s experience in fundamental research, industrial upgrading, and global competition—pursuing a transition from a manufacturing powerhouse to an innovation-driven nation.
