"I'd say this is a week where we've shifted from micro to macro issues and today's focus is ECB and jobless claims," said Art Hogan, managing director at Lazard Capital Markets.
Still, Hogan cautioned that the old Wall Street adage, "sell in May and go away" could still take place.
"As corny as that expression is, it's happened for the last three years," he said. "Something's going to derail this rally and a large cohort of people are looking for that pullback…at the very least, we'll continue to have mini-setbacks…we haven't seen much more than 2-percent pullbacks so far this year."
Weekly jobless claims dropped to its lowest rate since January 2008 last week, according to the Labor Department. The four-week average declined 16,000 to 342,250. Also on the jobs front, planned layoffs declined to the lowest level since last December and down nearly 23 percent from March, according to consultants Challenger, Gray & Christmas.

As expected, the ECB knocked down its key rate by a quarter-point to 0.50 percent,the first rate cut since July 2012, as global central banks raced to enact easier monetary policy. ECB chief Mario Draghi added that the monetary stance will remain accomodative for "as long as is needed."
Draghi told reporters at a press conference following the rate cut announcement that inflation could remain subject to some volatility throughout the year. "Overall, euro area economic activity should stabilize and recover gradually in the second half of the year."
On Wednesday, the Federal Reserve said it was prepared to "increase or reduce"the monthly pace of its $85 billion in bond purchases.

The company started trading under the ticker symbol "VOYA," and said it plans to rebrand the company as Voya Financial over the next few years.
Among earnings, General Motors rallied after the automaker posted stronger-than-expected earnings.

Meanwhile in Asia, shares fell across the board on Thursday after Purchasing Managers' Index (PMI) data showed Chinese factory growth easing, indicating that sluggish demand from the U.S. and Europe is weighing on Chinese exports.
Experts say that these factors, combined with Europe's high unemployment and easing inflation, could trigger a round of monetary stimulus from central banks around the world.
Also on the economic front, the U.S. trade deficit declined more than expected in March as imports posted their biggest decline since 2009, according to the Commerce Department.
