Share prices on the French Stock Exchange surged by well over 2.0 percent Thursday on the backs of renewed optimism about the ability of the US Administration and Congress to resolve the problem of impending default. The CAC 40 Index of premium stocks rose 2.21 percent to close at 4,218.11 points, the highest level since the beginning of the year.

Trading was brisk here Thursday, as over USD 4.7 billion (Euros 3.5 billion) changed hands during the day. Meanwhile, oil prices were also gaining ground in the more optimistic climate, rising around 2.0 percent in daily trading.
