US stocks muddled as Ukraine tensions fester

One positive report on the economy was not enough to make investors more confident. The stock market ended mixed after a day of muddled trading as tensions in Ukraine offset optimism over a pickup in hiring by US employers. The Labor Department said companies created 175,000 jobs last month, easily topping forecasts. While encouraging, the February report was not seen by investors as part of a broader trend. Biotech and health care stocks were among the biggest decliners. Bond prices also slipped. In other news, grocery store chain Safeway fell after the company said private equity firm Cerberus Capital would buy it for $9 billion.
