A new retreat in oil prices and Credit Suisse's ambitious earnings targets helped European shares rebound on Tuesday, but mixed economic data and a fall by the dollar to a new low kept a lid on market gains. French reinsurer Scor slid 6 percent after a U.S. jury decided to treat the Sept. 11 destruction of the World Trade Center towers by hijacked airliners as two separate events. Scor said it would fight the court decision, which it deemed contrary to the terms of the insurance coverage. The FTSE 300 index of pan European blue-chips ended 0.4 percent higher at 1,035.45, snapping a two-session losing streak that pushed the index 1 percent lower. The narrower DJ Euro Stoxx 50 index added 0.5 percent to 2,918.4. A new sharp fall in U.S. oil prices helped some companies, with fuel-hungry airline Iberia climbing 1.2 percent, even though market watchers said the retreat of crude prices to three-month lows may not last. "The fall in oil prices has certainly been a good thing for equity markets but I don't know to what extent that trend is sustainable because the winter months are not over yet," said Rohini Rathour, senior analyst at investment firm Sarasin Chiswell, who said this factor should nonetheless help equities stay "reasonably" strong in the short term. --More 2300 Local Time 2000 GMT
