Market research group Sentix released its investor confidence index for the Eurozone on Monday. The index rose to 5.7 in April from 5.5 in March.

A reading above 0.0 indicates optimism, below indicates pessimism.

"The process of economic stabilization of investors expectations has continued at the beginning of April," Sentix said in its statement.

"The Eurozone can benefit neither from a stabilization of the global economy nor from the measures of the ECB," Sentix added.

The current conditions index fell to 6.0 in April from 8.3 in March.

The expectations index climbed to 5.5 in April from 2.8 in March.

German investor confidence index rose to 17.6 in April from 16.9 in March.
