Study finds 'beautiful' CEOs boost stock prices Regular media appearances can also improve shares if the chief executive is attractive, the study found. "CEO attractiveness may also affect shareholder value through the visibility channel, in which media attention may affect a firm's investor base and stock prices," it said. We find that more attractive CEOs are associated with better stock returns on CEO-related television news days. Speaking to CNBC, the researchers said that Marissa Mayer, the 38-year-old chief executive of Yahoo!, was a good example, while being quick to stress that CEO attractiveness is only a small part of share performance. Since Ms Mayer charge of Yahoo!, the company's shares have risen by more than 150pc. "She scored 8.45 (out of 10) in our facial attractiveness index and is among the top 5pc in our sample," they said. Of course, we don't mean that all the increase in stock price is from her appearance. We just find that there might be some positive correlation between the two.
