MADRID (MarketWatch) -- U.S. stock futures were in the red Tuesday, but shook off deeper Greece-fueled losses ahead the latest housing-market index, the Empire state manufacturing reading and a Federal Reserve speaker, all due later in the day.

Futures for the Dow Jones Industrial Average (DJH5) eased 10 points to 17,972, while those for the Nasdaq 100 index (NDH5) gained 4.75 points to 4,381.75. Futures for the S&P 500 index (SPH5) dropped 2.4 points to 2,091.10.

Greece is -- still -- the word: U.S. markets were closed for Presidents' Day on Monday, so investors did not have a chance to react to the latest news on Greece until Tuesday. Talks among eurozone finance ministers broke down abruptly on Monday, after Greece's new anti-austerity government rejected an extension to its 240-billion-euro ($272 billion) bailout program under the conditions offered by its European partners.

Greek Prime Minister Alexis Tsipras and his finance minister, Yanis Varoufakis, said the terms of the deal hurt the Greek economy and society, and asked for looser conditions on the bailout program.

Greece's current program expires at the end of February. If negotiations end in a deadlock, the Mediterranean nation will lose access to the rescue loans that have kept it afloat for almost five years, potentially setting the scene for a default and Greece's withdrawal from the shared currency, or "Grexit".

"With investors starting to fret over the genuine prospect of Greece printing drachma in the coming weeks, it looks like global markets are in for a turbulent ride," said Mike McCudden, head of derivatives at Interactive Investor, in a note. "However, with a 'Grexit' remaining highly unlikely -- the eurozone traditionally taking negotiations to the wire -- any panic dips could present buying opportunities."

Finance ministers from the full European Union, known as Ecofin, were meeting on Tuesday, and a new meeting of the Eurogroup, a smaller group of eurozone finance ministers might be scheduled for Friday. Read: These 5 charts explain the latest Greek drama
