1980: 6 of the top 10 US companies were oil and energy giants.
2025: Zero energy stocks in the top 10. Nine are pure tech — arguably all 10 if you count Tesla as tech, not auto.
That's a complete sector rotation in 45 years. Not a trend. A structural shift.
Energy used to be the entire economy. Now it's code, chips, and cloud infrastructure. The companies that move bits, not barrels, run the world.
Doesn't mean energy is dead — it just means the value creators changed. Capital follows growth and margins. Tech had both. Oil had neither for most of this period.
Lesson: concentration risk is real, but so is missing the mega-trend. Diversification across sectors made sense in 1980. It still does today. Because in 2070, this list will look different again — and we have no idea what'll be on it.
