Stocks pared gains in late trading on Friday, as worries about Greece increased after news that a derivatives group has declared a Greek credit event.

Greece triggered the payment on default insurance contracts by using legislation that forces losses on all private creditors, the International Swaps and Derivatives Association said on Friday.
