While you were sleeping: UPDATED Oil boosts stocks as Russia backs cap
Equities on both sides of the Atlantic rose with the price of oil after Russia signalled it will join an agreement to curb output.
Many oil producers outside OPEC expressed a willingness to co-operate on output caps, Saudi Arabia's Energy and Industry Minister Khalid Al-Falih told an energy congress in Istanbul.
He added that he was "optimistic" there would be a deal that could lift prices to as high as $US60 by year-end.
"Russia is ready to join the joint measures to cap production and is calling for other oil exporters to join," Russian President Vladimir Putin says, according to Reuters.
Oil prices rallied, with Brent touching $US53.73 a barrel, the highest level in a year, in London.
"Mr Putin coming out to say Russia will be part of the initiative has added another layer of credence to the speculation there will be a co-ordinated cut," John Kilduff, partner at New York energy hedge fund Again Capital, told Reuters.
"At some point, the market will call them on it and say 'show us the cuts'. And at that point, the Saudis might be willing to underwrite the cuts on their own because they really want these high prices. To me, $US55 Brent is without doubt the next target."
Dow rises 88 points
Wall Street and energy stocks followed suit. The Dow Jones Industrial Average rose 88.55 points, or 0.5%, to 18329.04. The Nasdaq Composite Index climbed 0.7% to 5328.67 and the Standard & Poor's 500 Index rose 0.5% to 2163.66.
The Dow advanced as Apple, Exxon Mobil and Chevron shares gained, up 2.1%, 2.0% and 1.7% respectively, outweighed slides in Wal-Mart and Procter & Gamble shares, down 1.2% and 1% respectively.
