The Dow jumped and oil prices fell as the risk the United States would attack Syria appeared to fade on Syria’s accepting a proposal to put its chemical weapons under international control for dismantling. The S&P also gained. Crude oil lost $2.13, almost 2 percent, to close at $107.39 a barrel.

He said it’s close to the five-year anniversary of the financial crisis, and the Dow has more than doubled since. Apple dropped $11.53, or 2.28 percent, to $494.64 after investors were underwhelmed by its new iPhone lineup.
