Also, one could end up losing from a stock whose growth story is actually over or nearing its end.However, the Zacks Growth Style Score (part of the Zacks Style Scores system), which looks beyond the traditional growth attributes to analyze a company's real growth prospects, makes it pretty easy to find cutting-edge growth stocks.Our proprietary system currently recommends Marsh & McLennan (MMC) as one such stock.
