NEW YORK (TheStreet) -- Stocks were narrowly mixed by the final hour of trading Tuesday as earlier upward momentum faded. Crude oil closed at its highest level this year, helping to sustain a rally in the energy sector.

The S&P 500 added 0.02%, the Dow Jones Industrial Average fell 0.03%, and the Nasdaq slipped 0.06%.

Crude oil closed at its highest level of 2015 as investors predict weekly data out Wednesday will show a drop in domestic crude inventories. West Texas Intermediate crude gained 1.8% to $61.26 a barrel.

Major oilers Exxon Mobil (XOM), Royal Dutch Shell (RDS.A), BP (BP), and Total (TOT) were higher, while the Energy Select Sector SPDR ETF (XLE) climbed 0.9%. 

The Organization of Petroleum-Exporting Countries is expected to keep production at record highs when members meet on Friday. OPEC has a target of 30 million barrels per day and major player Saudi Arabia is currently producing oil at record levels.

"The current reality is still characterized by considerable oversupply, which is likely to be confirmed initially by OPEC's decision on Friday," Commerzbank analysts wrote in a note. "We therefore envisage short-term correction potential."

Juno Therapeutics (JUNO) climbed more than 7% after AstraZeneca (AZN) CEO Pascal Soriot reportedly expressed interest in buying the company, according to Bloomberg

Federal Reserve Gov. Lael Brainard struck a dovish tone in her first speech on monetary policy.

"Consumer spending so far this year has been undeniably weak," said Brainard in a speech at the Center for Strategic and International Studies in Washington. "I think there is value to watchful waiting while additional data help clarify the economy's underlying momentum in the face of the headwinds from abroad."

The Fed will meet on June 16-17 to discuss monetary policy. Brainard always has a vote in her role as a governor.

Factory orders in April declined 0.4%, a disappointing result after jumping 2.1% in March. Economists had expected the measure to remain unchanged.

European markets declined Wednesday after Greece submitted its latest list of reforms to creditors, though sources have told Reuters that the plan offers no major new concessions. Leaders of Germany, France and a number of Greece's other international creditors said on Monday they would work with "real intensity" to seal a deal to prevent Athens from defaulting.

Trouble in Greece is reaching a boiling point as the debt-ravaged country faces a repayment to the International Monetary Fund on Friday of 300 million euros ($329 million). In total, Greece needs to repay the IMF nearly 1.6 billion euros ($1.75 billion) this month.

"The negotiations between the Greek government and the official lenders remain in a state of flux," Morgan Stanley analysts wrote in a note. "A full solution appears unlikely at this stage."
