Naw Im just wanting to watch the daily average,They arent reporting on it as much on the radio these days, I actually found it right here on Tnet just click on money above.
Here's a good site for past performance or you can log into nasdaq.com for daily update http://www.tsp.gov/rates/returns-tsp.html
click on "Returns", then "Monthly Returns" and then "TSP Individual Funds"....quite scary!
