According to a recent survey by Pew, 80% of people considered women to be just as qualified to lead a company as men. In fact, many said they believed women were actually stronger than men in terms of being compassionate and organized leaders. But somehow, women only account for 4.8% of CEOs at S&P500 companies.
Maybe our perception of women is wrong? Maybe they're not properly equipped to run a major corporation?
For the ongoing project, Quantopian pitted the performance of Fortune 1000 companies that had women CEOs between 2002 and 2014 against the S&P500's performance during that same time period.
They found that cash invested only in Fortune 1000 stocks from companies with female CEOs had a whopping return of 348% over the past 12 years (shown in green on the graph below). And the correlation still held up when they stripped the top and bottom three performers from the female CEO index.
In the same period of time, a hypothetical portfolio made up of stocks from the S&P500 index would have returned just 122% (shown in blue).
