"In the past, financial researchers have examined the stock market performance of companies featured in such magazines and books as Fortune and In Search of Excellence. These findings, in general, have shown that the stocks of “most admired” or “excellent” companies have either underperformed or performed about the same as the stocks not so considered. The authors use Business Week’s list of highly rated growth companies and find evidence of underperformance of these stocks during the post-publication period."
