Wall Street stars join Silicon Valley gold rush

New York

ONE of the country's largest banks, Morgan Stanley, is losing its chief financial officer to Google in the most visible example yet of the flow of talent from Wall Street to Silicon Valley.

Ruth Porat, Morgan Stanley's chief financial officer since 2010, has been one of the most powerful women in a financial industry that has struggled to promote and hold on to its female executives. She is going to Silicon Valley while it is facing its own issues about gender balance.
