The U.S., joined by the Britain, China, France, Germany and Russia, agreed to a preliminary agreement with Iran to freeze the country's nuclear armament program to allow for negotiations for a comprehensive effort to limit the size and scope of its activities, that is, for only "peaceful" purposes. The two sides have six months in which to hammer out a full-fledged treaty.

Alcoa (AA) - Get Report jumped 3.8% to $9.59 as Goldman Sachs raised shares of the aluminum manufacturer to a "buy" from "hold" declaring that "the market is not fully appreciating Alcoa's solid position in growing value-added and high margin aluminum products for the aerospace and automotive industries." Goldman analyst Sal Tharani raised his 12-month price target to $11 from $8.
