Growth stocks are attractive to many investors, as above-average financial growth helps these stocks easily grab the market's attention and produce exceptional returns. But finding a great growth stock is not easy at all.In addition to volatility, these stocks carry above-average risk by their very nature. Also, one could end up losing from a stock whose growth story is actually over or nearing its end.However, the task of finding cutting-edge growth stocks is made easy with the help of 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.ADVA OPTICAL (ADVOF) is one such stock that our proprietary system currently recommends.
