Barclays Capital has hired Winston Wenyan Ma, senior v.p., marketing specialist and products structurer in equity capital and derivatives markets at JPMorgan in New York. He will join Barclays next month as associate director, reporting to Craig Orchant, head of corporate finance and risk management. Orchant was traveling and did not immediately return a call, but officials familiar with the hire said it is the first in Barclays' push into corporate equity derivatives (DW, 2/16). Ma left JPMorgan last week, where he reported jointly to Chris Harvey, head of the capital structure advisory and solutions team, and to Jeff Zajkowski, head of equity-linked capital markets origination. Harvey and Zajkowski did not immediately return calls. Reached on his mobile, Ma declined comment.
