John Bogle: all you need to know about investing in three words

Financial guru John Bogle, founder of the Vanguard Group, on the simple advice he received at the start of his investing career: "Nobody Knows Nothing". What is presented as fact is just opinion and investors need to be wary of believing they are smarter than everyone else.

Very often people who know nothing about investing give advice...

Every honest person who has ever worked in financial services will tell you this. ;)

Want to get an Active Fund Manager to shut up? Two words: Index Fund.

So true. But we ignore it and pay for useless advice anyaway

Nobody knows nothing = Everybody knows something
Double negative.

His first boss knew about solid investing precepts, but not much about proper grammar :-)
