24/7 Wall St. Closing Bell (ORCL, ITRI, CSX, ABB, GILD, BKS, BYD, CCO, CIE, DTG, HL, JAKK, M, MDT, PXD, SKS, WLK, THLD, CORT, GTXI, CHTP, WMT, WFT)

US markets opened higher this morning and traded higher for most of the day. The DJIA briefly rose above 13,000 for the first time in nearly 3 years. But in the early afternoon, apparently as a result of a failure to break through the 13,000 barrier, stocks turned south and all three indexes fell below their openings. The announced settlement in Greece boosted the market early, and climbing crude oil prices helped energy stocks all day. Commodity prices also rose today as the dollar lost strength. Crude oil was up sharply, with WTI crude up more than 2% at $105.50/barrel and Brent up 0.81% at $121.02/barrel. Gold settled at $1,758.50, up 1.9%, and a two-week high.

The unofficial closing bells put the DJIA up about 16 points to 12,965.99 (0.12%), the NASDAQ fell more than 3 points (-0.11%) to 2,948.57, and the S&P 500 rose 0.07% or nearly 1 point to 1,362.23.
