NEW YORK (CNNMoney) -- U.S. stocks were poised to open higher Monday, as investors felt encouraged by progress in Japan's nuclear crisis and AT&T's $39 billion deal to acquire T-Mobile USA.
Dow Jones industrial average (INDU), S&P 500 (SPX) and Nasdaq (COMP) futures were all about 1% higher ahead of the opening bell. Futures measure current index values against perceived future performance.
Over the weekend, Japanese engineers made progress in cooling nuclear reactors that had overheated following the devastating earthquake and tsunami that struck the country on March 11.
Meanwhile, turmoil in North Africa heated up over the weekend. The United States and its allies launched an airstrike on Libyan military targets, in an effort to subdue forces of Libyan leader Moammar Gadhafi.
"Not only is the Japanese situation looking better than it was where we ended last week, the situation in Libya is seeming tamed by unilateral forces -- and that's relieving some of the tension investors felt ahead of the weekend," said Mark Luschini, managing director of Janney Montgomery Scott.
Investors also welcomed an announcement from AT&T (T, Fortune 500) on Sunday, that it will acquire T-Mobile USA from telecommunications company Deutsche Telekom for an estimated $39 billion in cash and stock.
"Deal activity speaks of CEO confidence," Luschini said.
The new entity -- if approved by regulators -- would be the biggest in the United States, combining AT&T's 95 million customers with T-Mobile's 34 million users for a total of 130 million subscribers.
The Dow ended the week 1.5% lower, while the S&P 500 lost 1.9% and Nasdaq dropped 2.7%. The Dow and S&P 500 remain modestly higher for the year, but last week's declines have put the Nasdaq down 0.4% year-to-date.
