As I write this, Nvidia just hit a new all-time high and the Dow closed at a record. The S&P 500 just logged its best September in 15 years. Yet every headline and every financial TV segment is asking the same question: is this a bubble?

Every time the market pushes to new highs, the same question comes up: are we in a bubble? It’s a fair question. Stocks have been on a strong run, valuations are stretched in certain sectors, and optimism feels sky-high. That combination always makes investors uneasy.

It’s when we start to see the charts comparing now versus the dot-com bubble.

Yes, the similarities are eerily similar.

But does it tell the full story? Of course not.
