NEW YORK (TheStreet) -- Stocks turned slightly positive by mid-afternoon Tuesday as crude oil closed at $61 a barrel. Markets had traded lower earlier as a surge in the U.S. dollar stopped short a rally triggered by optimism over Greece. 

The S&P 500 added 0.09%, the Nasdaq was up 0.06%, and the Dow Jones Industrial Average added 0.16%. 

West Texas Intermediate crude rose 1% to $61.01 a barrel over Tuesday's session in a rally analysts characterized as a technical bounce. The commodity was also showing some buoyancy ahead of weekly inventories data out on Wednesday. 

The U.S. dollar gained 1.5% against the euro, 0.37% against the Japanese yen, 0.6% against the British pound and 0.23% against the Canadian dollar. 

Eurozone finance ministers reacted positively to new proposed reforms submitted by the Greek government in a meeting on Monday. Among the reforms reported, though not confirmed, Greece will eliminate early retirement benefits, cut defense spending and increase corporate tax rates. Eurozone leaders will meet again at the end of the week. Talks have escalated as Greece faces a crucial repayment to the International Monetary Fund by the end of the month.

U.S. manufacturing growth slowed again in June for the third straight month, falling to its slowest pace since October 2013, according to the Markit PMI Manufacturing Index. The survey fell to 53.4 in June, down from a May reading of 54. Economists had expected the measure to increase to 54.2.

Durable goods orders in May fell 1.8%, weighed on by a 35.3% month-on-month slide in the volatile commercial aircraft component. April's reading was revised down to a 1.5% decline from a previous 1% drop. Excluding transportation, the measure climbed 0.5%, above estimates of a 0.3% slip.

"The downward revisions to April's estimates suggest that there was a much weaker start to investment activity this quarter and despite the small rebound in May's investment activity the contribution to GDP this quarter from investment activity will remain quite modest at best," said Millan Mulraine, deputy head of U.S. strategy at TD Securities.
