Vanguard is the industry leader for low cost, diversified index funds. 6 of the 10 largest mutual funds in the world are Vanguard funds. Unlike their competitors, Vanguard is owned by their investors – like a credit union. This means they don’t need to increase their revenue. They’re optimized around increasing revenue for investors.
Minafi absolutely recommends Vanguard for anyone hoping to invest for retirement – despite the user interface that looks like it was created in the 90s.
