Vanguard is the best shop for index funds. Founder Jack Bogle first popularized index fund investing, launching Vanguard’s Standard & Poor’s 500-stock index fund in 1976. The firm is owned by its fund shareholders, meaning it’s essentially a nonprofit. Consequently, its fees are among the industry’s lowest. Unlike most competitors, moreover, it has long been committed to low fees. That means fees are unlikely to rise when investors aren’t paying attention.
