24/7 Wall St. Closing Bell (AIXG, AZN, HON, HUM, PAA, ALU, FTEK, IRDM, XIDE, WMS, JRCC, PKT, RJET, OPXA, DYN, TRGT, MSSR, SZYM)

Equities started the day with a solid move up, but lost momentum after about half an hour. The downward move lasted into the late morning, at which time stocks started a fitful climb back up. There was no big news to speak of, although the Italian prime minister lost a budget vote which may lead to vote of confidence in his leadership. Crude oil is up about $0.75/barrel and gold is up about $6.40/ounce, to near $1,800/ounce. Commodities are mostly higher as the dollar weakened. Stocks finished the day near session highs.

The unofficial closing bells put the DJIA up more than 101 points to 12,170.18 (0.84%), the NASDAQ rose more than 32 points (1.2%) to 2,727.49, and the S&P 500 rose 1.17% or more than 14 points to 1,275.93.
