<prompt> Human: Hi all-Ive noticed that VTSMX is gaining faster than the Dow has- setting up a basic comparison graph between the two on Yahoos website shows that its always a bit stronger than the Dow. I looked at the past 3 months- 2 years and the pattern remains. Is it possible that due to Vanguards recent publicity reputation that their index funds are actually being overvalued? Im thinking of a basic supplydemand element being at play here, in that more people are respecting and valuing Vanguards product and thus the price is being driven upwards by this demand. Thoughts?Link to relevant graphs-VTSMX vs Dowedit- I cant figure out how to link to a graph showing BOTH of them- all you have to do is click compare and type in VTSMX and itll show both superimposed.  <response>: VTSMX doesnt track the Dow. Theres no reason to think they would have identical performance.
