Wall Street bulls were taking a breather Monday after a three-week rally pushed markets up from a rough start to the year. But U.S. markets eked out slight gain after the bulls and the bears played tug-of-war for much of the day. The S&P closed just above 2,000 for the first time since Jan. 6.

European shares extended losses in the first trading session of the week as investors absorbed the latest economic news out of China and paused ahead of this week’s European Central Bank meeting.
