Using market signaling theory, we propose that attributes of the CEO send important signals to the investment community as to the credibility of the CEO certification and thus the quality of the firm's financial statements, which in turn impact the stock market reaction to the CEO certification. We find that a CEO's shareholdings and external directorships are positively related to the abnormal returns of CEO certification. Further, the stock market penalizes a firm with a CEO who is associated with the firm's prior financial restatement and rewards a firm with a CEO who is appointed after the firm's prior financial restatement.
