Index managers like Vanguard, don't try to outperform the market. Rather, they invest in all or a representative sample of the securities in the index and let markets do their work over the long term. By adopting a 'buy and hold' approach the cost of investing can be significantly reduced over time and lead to better returns for investors in the long term, especially on an after-tax basis. Because index funds invest in all or most of the securities in an index, they provide diversification, which means lower risk.
