Why Gwyneth Paltrow feels like an impostor CEO

There’s more evidence to suggest putting women into top leadership roles is good for business.

A new study from S&P Global Market Intelligence found that public companies with women CEOs or CFOs often were more profitable and produced better stock price performance than many of the companies that had appointed men to those roles.

The study looked at new CEO and CFO appointments for companies on the Russell 3000 Index over the past 17 years. All told, it considered 5,825 new appointments, of which 578 were of women.

Two years after appointing a female CEO, companies were perceived by investors as being less risky, the study found. And the companies saw improved momentum in their stock prices.
