The S&P 500 in 1960 was basically industrial America — 425 industrial companies, 50 utilities, 25 railroads. That was the economy.
Today it's 75 tech, 76 financials, 60 healthcare, 83 industrials spread thin across everything else.
The composition has completely flipped. Railroads are gone. Tech didn't exist. Energy used to dominate, now it's 21 names.
People say "this time is different" and they're half right — the market structure IS always different. The sectors rotate, the leaders change, the economy evolves.
But the behavior? The greed, fear, overconfidence, panic selling, chasing winners, ignoring risk — that part never changes.
You can't predict what the S&P will look like in 2060, but you can bet humans will still be making the same emotional mistakes.
The lesson isn't to fight change. It's to respect it while keeping your head when everyone else is losing theirs.
