24/7 Wall St. Closing Bell (GD, VALE, GMCR, GLW, CHK, ARG, ACAT, T, BMY, CAT, CY, LMT, MKC, MWW, POT, RTN, VIST, RNWK, MNTA, NFLX, EFSC)

All three major US indexes opened higher this morning, but enthusiasm tapered off quickly and steadily, if not sharply. A drop in the number of new home sales and a smaller-than-expected rise in the leading economic indicators index. Hope that talks between Greece and its creditors would yield an agreement also pushed markets higher. But the weak housing report and no further news from Europe kept share prices moving down. WTI crude gained 0.35% at $99.75/barrel and Brent crude is up 1.02% at $110.93. Gold is higher by 1.27% at $1,724.60.

The unofficial closing bells put the DJIA down more than 22 points to 12,734.63 (-0.18%), the NASDAQ fell about 13 points (-0.46%) to 2,805.28, and the S&P 500 fell -0.57% or nearly 7 points to 1,318.45.
