I am also getting tired of the AGG. TLT may be a better ETF to follow, but bonds were certainly strong yesterday. I'm not sure why the TSP did not pay off the F-funders.
The answer is likely on this MB somewhere. I looked at tsp.gov and couldn't answer the question. Don't have time to look more.
How does AGG show a .29% gain and the F fund share price go down .2%?
It's called Barclay's Math.
TSP posts daily prices. Why follow AGG?
AGG and F are two different funds. There is no reason that they should give the same return on a daily basis. They both follow the same index, so over the long term they should have similar returns. But not day to day.
The C and S funds have been figured out. The I-fund can be as well, although with fair value it can be tricky at times. So why not look for something to help with the last fund, the F fund? The AGG has been about the closests we've found, unfortunately.
The TSPLookup utility has done pretty good as well, but not everyone can run this at work.
Didn't know that a bond fund paid dividends ?
