Market research group Sentix released its investor confidence index for the Eurozone on Monday. The index climbed to 15.7 in December from 15.1 in November.

A reading above 0.0 indicates optimism, below indicates pessimism.

"The Eurozone outperforms other world regions as the effects of ECB's policy measures kick in. The remaining world regions depict signs of a slowdown. Japan slides back into recession. In contrast to Fed's interpretations of the state of the economy, the sentix indicator for the US economy highlights a contrary view amid the preparations for the first rate rise," Sentix said in its statement.

The current conditions index dropped to 13.5 in December from 16.0 in November.

The expectations index jumped to 18.0 in December from 14.3 in November.

German investor confidence index increased to 22.7 in December from 20.1 in November.
