Charts showed (AGG) F Bond fund closing at 109.66 11/29/11 which was up .04% from previous day close. TSP share prices posted down at .09% which was a negative 1.4 cents per share. Contacted TSP and they are sending for an explanation of my inquiry. I check the charts periodically and do the math many times before the share prices post and am usually within a fraction of what is posted. A .13% swing or 1.5 cents per share does not fall within my margin for error. Anyone else see this or have explanation?
