John Bogle created the index fund in the 70s and proved that on average it out performs all other finical products available to normal people (non billionaires). Warren Buffett won a million dollar bet a few years ago proving the same thing.
If there really was a company or hedge fund manager that could always outperform the market, everyone would use that person. If you do outperform the market, that has more to do with luck than skill.
