The chart of the week highlights how the top 10 U.S. companies by market value have evolved from 1930 to 2024. In the early years, industrial giants like AT&T, General Motors, General Electric, and Exxon dominated the rankings, maintaining their leading positions for much of the 20th century. However, starting in the 1990s and accelerating into the 2000s, technology companies began to rise to prominence. Notable names include Microsoft, Apple, Google, and more recently, NVIDIA, often grouped under acronyms like FAANG (Facebook, Apple, Amazon, Netflix, Google) and the Magnificent Seven. This evolution illustrates a significant shift from energy and manufacturing sectors toward technology and innovation as the primary drivers of corporate value.
