Event Anomalies

Occurrences that present the opportunity for an abnormal return. For example, a company may announce the hiring of a well-regarded executive as CEO. This could cause the company's stock price to jump temporarily; a shareholder could sell some shares at the artificially high price, generating a higher return than the shareholder expected when he/she bought the stock.
