June 26 (Reuters) - U.S. stocks were mixed in late morning trading on Friday as better-than-expected consumer confidence data brought some relief to investors concerned about a possible debt default by Greece.
University of Michigan's final reading on the overall index on consumer sentiment for June was 96.1, higher than its preliminary reading of 94.6.
"Investors are really craving healthy economic data. Any kind of incoming data that is stronger than expected is welcomed by the investor community," said Adam Sarhan, chief executive of Sarhan Capital in New York.
Greece on Thursday failed to clinch a deal with its international creditors.
Euro zone partners have offered to release billions in frozen aid in a last-minute push to win Greece's acceptance for a cash-for-reform deal.
"For most part we are trading off any news that comes out of Greece. I am looking for an agreement that falls somewhere in between full compliance and default," said Jack Ablin, chief investment officer at BMO Private Bank in Chicago.
