Credit Suisse on Thursday unveiled bumper Q3 results as the Swiss banking group reported a surge in its investment banking activities and solid results in private banking. Group net profit reached SFr2.35bn ($2.33bn), up from a SFr1.3bn loss last year and a net profit of SFr1.57bn in Q2. Return on equity jumped to 25.1%. The upbeat results prompted a confident outlook statement from Brady Dougan, the bank’s normally cautious chief executive.
