Grall October 21st | American medical insurance giant the cigna group (CI.US) continued to fall more than 4%, with a consecutive drop of nearly 10% in two days. According to Bloomberg, citing sources familiar with the matter, the company has restarted merger plans with its smaller competitor Humana, with the two companies recently engaging in informal early-stage discussions about a potential trade. It is worth noting that Cigna ended acquisition negotiations with Humana at the end of last year because the two companies failed to reach a price agreement. Cigna then announced a $10 billion stock buyback, leading to a significant surge in the company's stock price. (Grall)
