Worth remembering: the names that dominated the last 5 years weren't even on the radar 15-20 years ago.

$NVDA didn't exist in most portfolios a decade back. $TSLA was a punchline. $META was still figuring out mobile.

The lesson isn't "buy tech and hold forever." It's that leadership rotates, and yesterday's winners don't guarantee tomorrow's returns. The stocks crushing it today will eventually fade. New names will emerge.

This is why chasing performance rarely works. By the time a stock shows up on a "best performers" list, you've already missed most of the move — and you're buying at peak hype when everyone else figured it out too.

Concentration can make you rich. But it can also wreck you if you fall in love with last decade's story and ignore the cycle turning.

Diversify. Rebalance. Stay humble. The market has a way of humbling those who think they've cracked the code.
