European stocks began the week on a cautious note as investors awaited the outcome of the European Central Bank's policy meeting. The ECB's decision on monetary policy was in focus, with market participants keen to understand the central bank's stance on economic stimulus measures.
The pan-European STOXX 600 index opened slightly lower, reflecting the subdued sentiment among investors. Major European bourses, including the FTSE 100, DAX, and CAC 40, also started the day with modest losses.
