"The bottom line is that the headline gain is all transport/aircraft driven, but the details are miserable," said David Ader, a strategist at CRT Capital Group.

Investors were also cautious as they awaited concrete development from talks between several European leaders this week.

Greek Prime Minister Antonis Samaras met with German Chancellor Angela Merkel in Berlin Friday, and was expected to meet with French President Francois Hollande in Paris Saturday, as Athens sought an extension of its bailout terms.

During a joint press conference with the Greek leader Friday, Merkel said Germany stands ready to support Greece as it tries to ease the country's economic challenges.

"The Greek PM and the German Chancellor meet to swap holiday photos," commented Paul Donovan, global economist at UBS. "After her cozy chat with French President Hollande yesterday, Merkel reiterated the importance of the Troika report on Greece. This seems to be becoming a fig leaf to cover up any embarrassment over changing the bailout duration."

In the days ahead of the meetings, Eurozone leaders asserted that the decision on providing fresh aid to Greece won't take place until international lenders have completed their review of the country's progress in reaching financial targets.
