Vanguard: The Gold Standard of Passive Indexing

Last Updated: April 19, 2026

Vanguard is basically the "default" setting for modern Investing. When Jack Bogle started the firm in the 1970s, people thought he was crazy. He argued that most active managers couldn't beat the market after fees, so why not just buy the whole market and pay next to nothing? Decades later, that idea has won.

Vanguard is now a behemoth, and for good reason. We've seen how their unique structure helps keep costs down: the people who own the funds own the company. This means they don't have outside shareholders breathing down their necks for profits. Instead, they pass those savings back to you in the form of lower fees (and let's be honest, that is exactly why they remain the industry leader).
