A look at highlights from the day's business news:
Stocks slip on Portugal credit woes
Stocks closed lower Wednesday as the dollar strengthened on fears tied to the growing fiscal crisis in Europe and a dour report on U.S. sales of new homes raised concerns about the economic recovery.
The Dow Jones industrial average fell 53 points, or 0.5 percent. The S&P 500 index slid 6 points, or 0.5 percent. The Nasdaq composite dropped 16 points, or 0.7 percent. All three indexes remain near the highest levels since late September 2008.
Stocks opened lower after ratings agency Fitch cut Portugal's sovereign credit rating one notch, reigniting concerns that the debt problems of struggling European economies like Greece are spreading and could hurt stronger members of the European Union.
The downgrade battered the euro, which fell to a 10-month low versus the dollar. The stronger greenback weighed on commodity prices, driving oil down 1.7 percent.
Stocks were also pressured by weaker-than-expected reports on new-home sales and durable goods orders. But analysts said the data are consistent with an economic recovery, albeit an uneven one.
