<prompt> Human: On Vanguards page for their Total Bond Market Index Fund it lists about a 5 annual yield for the last 10 years. The graph shows 10000 growing to 16000 over 10 years, so a 60 increase. However when I search VBMFX on Google, the value didnt increase that much, from 9.67 in 2006 to 11.18 in 2016, a 15 increase. I feel like theres an obvious answer but I dont know what it is. Why the discrepancy?  <response>: Because Google is only tracking fund price, not distributions, which is where most bond fund returns will come from.
