In CAPM, an investment performance that exceeds the predicted return, i.e., the risk free rate + the equity risk premium.
                                                            
                                                     
                        
                                                
                        
                        
                            The return achieved by a security over and above that obtained from a risk-free asset (such as a short-term government bond) held over the same period.
                                                            
                                                     
                        
                                                
                        
                        
                            Return relative to the risk-free return. If an asset return is 10% and the risk-free return is 5%, then the asset's excess return is 5%. The benchmark's return can be substituted for the risk-free return.
                                                            
                                                     
                        
                                                
                        
                        
                            The difference between the returns of two portfolios. Usually excess return is the difference between a manager's return and the return of a benchmark for that manager.
                                                            
                                                     
                        
                                                
                        
                        
                            The return on a security which exceeds that obtained from a risk-free asset (such as a short-term government bond) held over the same interval.
                                                            
                                                     
                        
                                                
                        
                        
                            The return derived from a security (during a specified holding period) less the return from holding a riskless security (such as a short-term government obligation) during the same period.
