European shares edged lower on Monday, as risk appetite showed signs of waning at the beginning of the final trading month of the year.

The pan-European Stoxx 600 declined 0.2% to 575.28. The DAX in Germany slipped by 1%, the CAC 40 in France dropped by 0.3%, and the FTSE 100 in the United Kingdom fell by 0.2%.
