J.P. Morgan Chase's Wall Street division just promoted 117 people to its highest rank of managing director, and a record number of women earned the title. Of this year's incoming class of managing directors, 26% were women, up from 18% last year, according to a person with knowledge of the figures. Of these 30 women, seven made use of the bank's maternity leave policy in the past two years, the person said. Bank CEOs from J.P. Morgan's Jamie Dimon to Goldman Sachs head David Solomon have said that hiring and promoting women and minorities are priorities for their trading and advisory businesses, which are still dominated by men, especially at senior levels. For instance, last month Goldman expanded a year-old program to hire more junior bankers from underrepresented groups.
