Wall Street could struggle to repeat strong gains on Tuesday, with just a smattering of data and mergers-and-acquisitions news to break up the day.

FedEx Corp. (http://www.marketwatch.com/story/fedex-to-buy-tnt-express-for-48-billion-in-cash-2015-04-07)(FDX) shares were moving higher after the parcel-delivery company said it will buy a Dutch logistics company as it seeks to expand its European operations.

Futures for the Dow Jones Industrial Average (YMM5) inched up 4 points to 17,809, while those for the S&P 500 index (ESM5) dipped 0.7 point to 2,072.50. Futures for the Nasdaq- 100 (NQM5) rose 2.75 points to 4,345.

Stocks finished with solid gains on Monday (http://www.marketwatch.com/story/us-stocks-futures-tumble-after-jobs-data-triggers-corporate-profit-worries-2015-04-06), lifting the Dow industrials (DJI) nearly 120 points and the S&P 500 (SPX) by nearly 14 points. Stocks rose on fresh thinking among market observers that last Friday’s weak jobs data could mean a slower pace of rate rises than previously expected. New York Fed President William Dudley gave stocks a further lift when he reiterated on Monday that any decision to hike rates will be data dependent.

In a catch-up move and returning from a long holiday weekend, European stocks (http://www.wsj.com/articles/permira-cppib-poised-to-take-informatica-private-in-5-billion-deal-1428398039) rallied across the board on Tuesday.

That stock runup should be accompanied by a dose of wariness, says some market observers. The average of jobs creation for 2015 so far is still above 200,000, and the dismal nonfarm-payrolls report could see a revision when next month’s data are published, Stan Shamu, market strategist with IG, said in a note.

“As far as the Fed is concerned, it is unlikely that one month’s data will make all the difference, and we know the central bank only has to be reasonably confident that inflation and jobs will trend toward target over the next couple of years for it to act,” said Shamu.

Data for Tuesday includes February job openings at 10 a.m. Eastern Time and consumer credit for February at 3 p.m. Eastern. Minneapolis Federal Reserve President Narayana Kocherlakota will speak in Bismarck, North Dakota at 8:50 a.m. Eastern.

Stocks to Watch: Shares of FedEx Corp (http://www.marketwatch.com/story/fedex-to-buy-tnt-express-for-48-billion-in-cash-2015-04-07).(FDX) were up 3% after the shipping giant announced the $4.8 billion deal to buy TNT Express NL (TNTEY). Shares of TNT jumped 31% in Amsterdam.

In what could be the biggest U.S. leveraged buyout of the year so far, Informatica Corp.(INFA) is nearing a deal to be taken private (http://www.marketwatch.com/story/informatica-poised-to-be-taken-private-in-5-billion-deal-2015-04-07) by Permira Advisors LLC and the Canada Pension Plan Investment Board, according to persons familiar with the deal, The Wall Street Journal reported.

SeaWorld Entertainment Inc. (SEAS) may grab some attention after the theme-park company said it has started an advertising campaign (http://www.marketwatch.com/story/seaworld-launches-ad-campaign-focused-on-killer-whales-2015-04-06) to counter “misinformation” and highlight its commitment to the care and research of killer whales.

Other markets: Oil (http://www.marketwatch.com/story/oil-eases-with-us-stockpiles-production-back-in-focus-2015-04-07)(CLK5) gave back part of Monday’s strong rally. Goldman Sachs said in a note that oil prices need to fall in coming months (http://www.marketwatch.com/story/oil-prices-to-stay-lower-for-longer-says-goldman-sachs-2015-04-07) to slow down U.S. production growth.
