🌟 Epilogue – The S&P 500 is Not a Number

It’s a narrative—a mirror of American capitalism, from factories to firewalls, from Ford to FANG. It absorbs recessions, revolutions, and renaissances, always reshaping itself, always marching forward.

It tells us where we’ve been.
It hints at where we’re going.
It’s not just 500 companies—
It’s the heartbeat of the market.
