Eight weeks after taking over as co-heads of JP Morgan's equities business globally, Mark Leung and Jason Sippel have named their top team, promoting several executives in the process.

Leung, who has worked for JP Morgan since 1997 and previously ran Asia-Pacific equities, and Sippel, a 14-year veteran of the bank who previously led prime services, took over the global equities business after the departure of Tim Throsby to Barclays, where he will be president of the corporate and international division.
