NEW YORK (Reuters) - Stock futures pointed to modest gains at the open on Monday as weak data on Chinese manufacturing raised hopes of fresh Chinese stimulus to combat slowing momentum, though tensions over Ukraine weighed on sentiment.
* Recent momentum on Wall Street has been to the upside, with the S&P 500 <.SPX> hitting an intraday record on Friday, though it subsequently ended the day lower. Equities have been lifted by some positive domestic data and a belief that the biggest East-West conflict since the Cold War will not escalate.
* Geopolitical concerns continued Monday after Ukraine announced the evacuation of its troops from Crimea, essentially yielding the region to Russian forces, which earlier seized a Ukrainian marine base there. U.S. President Barack Obama, who has imposed personal sanctions against some of Russian President Vladimir Putin's political and business allies, began crisis talks with his European allies.
* While few U.S. companies have excessive exposure to the region, investors are concerned about the potential economic fallout of any escalation in tensions.
* China's manufacturing engine contracted in the first quarter of 2014, according to the flash Markit/HSBC Purchasing Managers' Index. The report came in below expectations but raised hopes for new stimulative measures.
* Accommodative monetary policies from the U.S. Federal Reserve have fueled market gains for months, though the central bank has gradually been withdrawing stimulus. Last week, concerns mounted after Fed Chair Janet Yellen raised the possibility of an earlier-than-expected increase in interest rates.
* S&P 500 futures rose 5 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures added 28 points and Nasdaq 100 futures rose 9 points.
* Both the Dow <.DJI> and S&P closed their third positive week of the past four last week, while the Nasdaq has been up for six of the past seven weeks.
* Investors are looking ahead to the final March reading on manufacturing from financial data firm Markit. The report is scheduled for release at 9:45 a.m. ET (1345 GMT) and is seen slowing slightly from the previous month.
