Stacey Cunningham Is the First Female President of the NYSE

Stacey Cunningham always knew she was one of few women to ever work on the trading floor — but she didn't let that deter her from pursuing a career in a male-dominated industry.

This year, she became the first female president of the New York Stock Exchange — the largest stock exchange in the world, which, notably, didn't have a first female member until 1967 — about 175 years after it was founded.
