<prompt> Human: Has anyone had their money in an ETFIndex fund for 10 consecutive years? What was your avg. annual return? Is it comparative to what it claims on the charts?I see a lot of Vanguard that says avg return is around 10-11 over a 10 year period. Seems too good to be true.Assistant: Thats literally the average return on the market without adjusting for inflation. Vanguard prides itself on low cost index funds so a lot of their funds just track the market.Human: Do you have to have your money in Vanguard to have access to their index funds? Or can you have it in fidelity, charles schwab, etc.?  <response>: You dont have to, but it tends to be easier. However, Fidelity and Schwab both have their own in-house equivalents to all of the major Vanguard index funds, and they all perform pretty much equally.For example, VTSAX FSTVX SWTSX for all practical purposes
