Knee-Jerk Investors

The instant CNBC's Jim Cramer mentions a stock-sometimes even if he doesn't like it-viewers start purchasing it after hours,according to the ticker scrolled during his Mad Money program.Jim hates this,but nothing he says does any good.These viewers worship him and exercise no judgement whatsoever.What will they do when Cramer retires? And Cramer can be wrong about stocks.These viewers can lose money right now. Is Cramer doing more harm than good? No one has done a study to this point.We can only pray that isn't the case,since Jim is the channel's most original host.
