April 30 (Reuters) - U.S. stocks rose on Monday as strong earnings reports from McDonald's and a slate of merger announcements lifted sentiment, while inflation worries were kept in check after tepid data on U.S. income and spending.
McDonald's jumped 5.3 percent after the world's biggest fast-food chain by revenue topped analysts' forecasts for profit and sales.
Shares of oil refiner Andeavor surged 14.4 percent, the biggest percentage gainer on the S&P 500, after rival Marathon Petroleum agreed to buy the company for more than $23 billion. Marathon's shares slid 4.2 percent.
"The big news was really the deals, that continue the trend of strong M&A environment," said Aaron Clark, portfolio manager at GW&K Investment Management in Boston, Massachusetts.
Walmart rose about 2 percent after Sainsbury's agreed to buy the UK arm of Walmart, Asda, for about $10 billion, while Marriott Vacations Worldwide said it would buy timeshare operator ILG Inc for $4.7 billion, sending the target company's shares up 4.5 percent.
Another big deal announcement was that of T-Mobile's $26 billion takeover of fellow wireless carrier Sprint . Sprint shares fell 13.5 percent as analysts said it could face antitrust hurdles and the offer was seen as less favorable than an earlier one.
"Muted reactions to what was very strong earnings, capex spending picking up and strong M&A applies to what I'd say is part of classic late-cycle behavior," said Clark.
