Current events in business leadership can impact stock prices but short term effects depend on the nature of the change. Mark Hurd, once considered one of the best CEOs, stepped down from HP following a sexual harassment scandal. He was then hired by Oracle, whose CEO is his tennis buddy, replacing the previous president. While leadership changes may cause stock fluctuations, Oracle's stock prices did not significantly drop after this change according to Yahoo Finance data, suggesting the type of change matters more than the change itself.
