Swiss staffing firm Adecco said both its chief executive and chief financial officer had decided to leave, casting a cloud over its future as it posted its best ever first-quarter result.
In a surprise announcement, the group said CEO Patrick De Maeseneire would step down at the end of August, while CFO Dominik de Daniel would leave at the end of July.
"That both the CEO and CFO are jumping ship leaves behind a stale taste," said on Zurich-based trader. "Both have successfully led the company. That creates uncertainty, and investors hate uncertainty."
Shares in Adecco, which have outperformed the Swiss market this year by rising almost 10 percent, were indicated down 1.9 percent, according to premarket indications by bank Julius Baer.
During his six years at the company, De Maeseneire has helped Adecco grow in the higher-margin professional staffing business and launched a global I.T. platform to prepare for the digital age.
