The Magnificent 7 entered 2025 among the Top 10 largest US stocks. But before making an outsize bet on gains from these technology giants, investors should consider a few lessons from market history.
- It’s hard to stay on top. For example, only three of the 10 biggest companies from 1980 made the 2000 list—and none of them was in 2025’s Top 10.
- Industries ebb and flow. Technology-focused firms currently dominate the list. But in 1980, six of the 10 largest companies were in the energy sector.
- New technology doesn’t benefit only tech firms. Throughout history, companies across industries have used technology to innovate and grow
