With Comcast's stock price down 43% this year, a major shareholder has called for the  cable operator to give CEO Brian Roberts the boot. The proposal has met a tepid response, the Wall Street Journal reports. The call for Roberts' head is premature, say analysts and investors, especially given the current industry-wide cable slump.
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        Major shareholder Chieftain Capital Management Inc., demanding Roberts' ouster, called his decade-long leadership a "zero-return" "Comcastrophe." Other investors counter that the roots of many of the company's problems lie in the floundering economy and competitors' heavy investment in fighting Comcast. They contend Roberts' departure without a heir apparent would solve nothing.
