24/7 Wall St. Closing Bell (AAPL, DELL, MOS, GILD, DNDN, BAS, CYH, LOPE, RRC, CETV, CHS, DLTR, GRMN, NG, RRD, TOL, HSTM, FIRE, THLD, NFX, CELL)

US equities markets opened lower this morning following surprisingly weak manufacturing reports from Europe and China. Fitch Ratings’ downgrade of Greek debt to ‘CCC’ could not have been a surprise, but the move highlighted the doubts about whether or not Greece will be able to meet its new obligations. The new home sales report was weaker than expected (see our coverage here) and rising crude oil costs also kept markets on the downside. Indexes remained in negative territory for most of the day and are set to close with modest losses. Crude oil was higher today, with WTI crude up 0.02% at $106.27/barrel and Brent crude up 1.23% at $123.16/barrel. Gold settled up 0.7% at $1,771.30, a three-month high.

The unofficial closing bells put the DJIA down almost 27 points to 12,938.75 (-0.21%), the NASDAQ fell more than 15 points (-0.52%) to 2,933.17, and the S&P 500 fell -0.33% or nearly 5 points to 1,357.66.
