24/7 Wall St. Closing Bell (AMZN, CAM, MPEL, NVDA, SVU, RF, DDS, DHI, BONE, CDTI, HHC, PNS, ALIM, PSDV, MCP, HOVNP, TRX)

The markets got off to a strong start this morning, and stayed that way throughout the day. The dollar weakened against the euro and yen as currency traders seem to believe that a solution to the mess in Europe is getting nearer. Trading volume has been moderate today, perhaps due to the bond market holiday. Gold closed at $1,788.10/ounce, up 1.6% and silver closed near $34.69/ounce, up 1.7%. Crude oil settled within just below $99/barrel, its highest point in about three months.

The unofficial closing bells put the DJIA up more than 259 points to 12,153.46 (2.18%), the NASDAQ rose more than 53 points (2.04%) to 2,678.75, and the S&P 500 rose 1.95% or more than 24 points to 1,263.85.
