Investors seek growth stocks to capitalize on above-average growth in financials that help these securities 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.Our proprietary system currently recommends Sonoco (SON) as one such stock.

And for stocks that have a combination of a Growth Score of A or B and a Zacks Rank #1 (Strong Buy) or 2 (Buy), returns are even better.Here are three of the most important factors that make the stock of this packaging maker a great growth pick right now.Earnings GrowthEarnings growth is arguably the most important factor, as stocks exhibiting exceptionally surging profit levels tend to attract the attention of most investors. And for growth investors, double-digit earnings growth is definitely preferable, and often an indication of strong prospects (and stock price gains) for the company under consideration.While the historical EPS growth rate for Sonoco is 6.6%, investors should actually focus on the projected growth.

Comparing this to the industry average of 0.96, it can be said that the company is more efficient.While the level of efficiency in generating sales matters a lot, so does the sales growth of a company. And Sonoco looks attractive from a sales growth perspective as well. The company's sales are expected to grow 32.4% this year versus the industry average of 9.9%.Promising Earnings Estimate RevisionsBeyond the metrics outlined above, investors should consider the trend in earnings estimate revisions.
