CEOs should tell more jokes on earnings calls – stocks tend to perform better when they do, study finds

• CEOs can boost their company's share price by telling jokes, according to a paper published earlier this year.
• "When managers use humor on an earnings call, stock market returns… are more positive," researchers said.
• Just 12% of earnings calls feature any comedy at all, per the study.

It might be time for CEOs to start telling more jokes, according to a paper published in the Review of Accounting Studies earlier this year.
