    The returns of the TSP funds may, from time to time, differ from the index returns. Also, some of the money in the F, C, S, and I Funds is temporarily invested in the G Fund and earns the G Fund return.
    The prices reflect returns on investments, accrued administrative expenses, and trading costs.

Apologize if this isn't the right place to put this but I was just checking my account balance over the past year to compare the share prices of the TSP C Fund to the S&P 500 and there seems to be a large difference between the two deltas when they are compared. I was hoping one of you might be able to help explain the large difference (delta) to me. The delta in share prices for the TSP C Fund from 25 Aug 2014 ($26.1660) to 25 Aug 2015 ($24.9844) is a change of -4.5157%, whereas the delta in the S&P 500 from 25 Aug 2014 (1997.92) to 25 Aug 2015 (1,867.61) is a change of -6.522%, which makes the difference between the share price delta (-4.5157%) and the S&P 500 delta (-6.522%) at 2.00%. I know the share prices of the TSP C Fund do not exactly match the S&P 500 but this 2.00% difference seems to be excessive. Could you please explain this? Here are the numbers:

    TSP C Fund as of 25 Aug 2014 = $26.1660 per share
    TSP C Fund as of 25 Aug 2015 = $24.9844 per share
    Delta = -4.5157% per share

    S&P 500 as of 25 Aug 2014 = 1997.92
    S&P 500 as of 25 Aug 2015 = 1867.61
    Delta = -6.522%

    Difference between two indices = 2.00%

    What this means in practical terms is that over the same time period the TSP C Fund has lost only 4.5% per share whereas the S&P 500 has lost 6.5% overall. Why?

    I was going to say dividends, but userque covered it all.

    Thanks for your responses. It looks like the only explanation that could account for the 2% difference between TSP share price and S&P 500 is dividends that are priced back into the TSP share price. The admin expenses and trading costs would actually make the share price lower than the S&P 500. Still, 2% seems pretty steep for the delta. That's some good dividends!

    Absolutely. I included that part for completeness. I properly assumed you would understand that they are expenses.
