If the CEO is single, the company’s stock will swing

CEOs who are male and single are bigger risk takers and their company’s stock is more volatile, according to a study by the University of Pennsylvania.

Nikolai Roussanov and Pavel Savor, finance professors at the school, found same phenomenon amongst mutual fund managers who “. . . exhibit greater idiosyncratic risk exposure than their married peers.”

The authors believe that CEOs who are male and who are not married pursue riskier strategies to accumulate wealth, gain status and possibly find a mate. The reverse behaviours are exhibited by CEOs who are married and face a whole different set of motives:

“As long as changing mates over time (e.g., through divorce) is costly, married individuals will exhibit weaker concern for relative wealth position, all else equal,” writes the authors.

Older CEOs are also found be less risk averse.
