Jenny Su, a senior private-banking executive at UBS, has left the firm, following the recent departure of three other team members. This change comes amid a broader trend of executive turnover within the financial sector in Switzerland. In a separate development, the chief medical officer of WW International, commonly known as WeightWatchers, has also stepped down after less than a year in her role. This resignation follows reports of financial challenges faced by the company. The departures highlight significant shifts in leadership at both UBS and WeightWatchers, reflecting ongoing changes in their respective industries.
