U.S. stocks surged for a second day on Thursday, with the Dow turning higher for the year, as the price of oil steadied and on thinking the Federal Reserve and the European Central Bank would buttress the global economy. The CBOE Volatility Index (^VIX), a measure of investor uncertainty, fell 12 percent to 17.09. Comments late Wednesday by Fed Bank of Chicago President Charles Evans helped the bullish slant, with Evans saying he did not believe the central bank should be in a rush to hike interest rates.

In a letter to European lawmakers, ECB President Mario Draghi said the ECB would reassess its monetary-policy stance early this year, and that ECB moves could include sovereign bond purchases, Bloomberg reported on Thursday.

“Three things are driving the market significantly higher this morning as a follow on to yesterday’s strength,” Art Hogan, chief market strategist at Wunderlich Securities, said.

“First and foremost, continued stabilization in the energy market; number two, after the close, Fed President Charles Evans commenting that the Fed may not move until 2016 put a bid in futures last night and that that’s holding this morning, and third anticipation that the ECB will actually start outright quantitative easing at their meeting, which is later this month,” Hogan said.
