Reuters reports that a ZEW survey showed that German investor sentiment rose in December on expectations that vaccines against the coronavirus will boost the economic outlook.

Investors' economic sentiment index moved up to 55.0 from 39.0 in the previous month. Economists had expected an increase to 45.5.

A separate gauge of current conditions decreased to -66.5 from -64.3 in the previous month. That compared with a consensus forecast of -66.0 points.

"The announcement of imminent vaccine approvals makes financial market experts more confident about the future," ZEW President Achim Wambach said in a statement.
