European stocks experienced a notable rise during the earnings season, with the STOXX 600 index reaching a one-week high. Key contributors to this upward movement included HSBC Holdings, which saw a gain of 4.5% following the announcement of a $3 billion buyback plan. Other notable performers included Corbion, which increased by 5.0% after raising its guidance in its Q3 results, and Ceconomy, which rose by 3.5-4.0% due to a positive Q4 trading update. Novartis also reported a 2.0% increase after raising its guidance, while Adidas gained 1.5% after affirming its guidance in its final Q3 results. The overall positive sentiment was somewhat tempered by mixed earnings reports, as indicated by the performance of the broader market.
