U.S. stocks closed in green on Monday after German Chancellor Angela Merkel's government agreed on the European Central Bank's bond-purchase plan.
"There's better general feeling," Richard Sichel, chief investment officer at Philadelphia Trust Co., said.
"We've had a good earnings season and better-than-estimated data last week. The weekend didn't bring any painful news out of Europe and there are expectations the ECB will buy bonds."
