UBS Special-Situations Head Gueikian Said to Quit

Cesar Gueikian, global head of UBS AG’s special-situations group, quit Switzerland’s biggest bank to start a hedge fund with former colleague Andres Scaminaci, three people with knowledge of the matter said.

The departure was confirmed by Gueikian, 35, in a telephone interview, as well as by Megan Stinson, a spokeswoman for the Zurich-based bank. Theo Constantinidis, who led the unit with Gueikian, will become its sole head, Stinson said. The pair oversaw a team of about 25 people in New York, London and Hong Kong.
