The idea
Picking single winning stocks is really hard — even experts often get it wrong. An ETF solves that: it's one basket holding hundreds or thousands of companies, so you own a little of everything with a single tap. Buy one share of an index fund like VOO and you instantly own a slice of ~500 big US companies. 📦
