(CNBC) U.S. stocks traded higher on Thursday as investors cheered a cease-fire agreement between Russia and Ukraine and firming oil prices.
"I think the market is taking its cue off Putin's announcement of a cease-fire agreement," said Peter Cardillo, chief market economist at Rockwell Global Capital. He also expected a compromise to come out of Greece and the euro zone soon.
Greece was unable to reach a deal with the European Union to stay in an EU bailout program, the Eurogroup's Jeroen Dijsselbloem said on Wednesday, noting talks will continue on Monday.
