C Fund and S&P 500

Can someone please explain why the S&P 500 was up yesterday and the C fund wasn't? I thought the C fund followed the S&P 500?

Thank you,

Mike

It would have been up about a half a penny (+.04%). I guess rounding came into play.

Sure thing. Its called an expense ratio of 0.1%. Very few things in life are free, and the C fund isntone of theexceptions.
