Investors must have eaten their Wheaties this morning, but forgotten their afternoon protein shake. Stocks hit new milestones Thursday shortly after the markets opened before pulling back.
US markets had been on a roll this week. On Wednesday, the S&P 500 closed at a new high, it's eighth of the year. But the question remains as to whether this momentum will continue.
Investors are keeping an eye on U.S. jobs and Europe's economy. The big March unemployment report is due tomorrow. Today the Labor Department released jobless claims data for late March, and it was worse than expected, raising concerns about what could be coming on Friday.
Across the pond, the European Central Bank said it will keep its key interest rate unchanged at 0.25%, as widely expected. But the central bank is facing growing pressure to do more to stimulate the Eurozone economy as risks of deflation rise and the euro remains stronger than some would prefer.
ECB President Mario Draghi tried to use words to calm the markets. He affirmed in a press conference the bank's commitment to keep inflation at a healthy level, but he didn't announce any new measures to prop up the economy.
Still, he said said the ECB's governing body is considering a quantitative easing strategy similar to that deployed by the Federal Reserve.
European markets finished mixed following the announcement.
In corporate news, newly issued Google shares started trading Thursday as a result of the tech giant's long-anticipated 2-for-1 stock split.

Old Google class A shares, which retained their voting rights and trade under the new symbol, "GOOGL," went up in the morning and then fell back.
Shares of both classes of Google began trading at around $570, but the A shares have maintained a higher share price all day, as expected.
Some traders on StockTwits were caught off guard by the split.
