Stacey Cunningham - President, New York Stock Exchange

In a special 100 Women interview, Samira Hussain talks to the president of the New York Stock Exchange. Stacey Cunningham is the first woman to occupy that post and is one of a few women in very senior positions in a very male-dominated industry. She talks about her rise from the trading floor to the top of the institution, society's expectations of women and if her industry is due its #MeToo moment.
