Renewed concern over Greece and weak results at companies such as Siemens and Philips halted a winning run on European stock markets on Tuesday, Reuters reported. The pan-European FTSEurofirst 300 index, which had risen for the last eight sessions, slipped back by 0.3 percent to 1,484.07 points going into the middle of the trading session. The euro zone's blue-chip Euro STOXX 50 index also declined 0.7 percent, retreating after a similar eight-day winning streak. Those gains were ignited by the European Central Bank's plans to buy back government bonds to spur growth in the struggling euro zone economy. Greek shares underperformed for the second day in a row. The benchmark Athens ATG equity index fell 2.6 percent and Greece's borrowing costs rose.
