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. However, it isn't easy to find a great growth stock.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, it's pretty easy to find cutting-edge growth stocks 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.Quanex Building Products (NX) is one such stock that our proprietary system currently recommends. The company not only has a favorable Growth Score, but also carries a top Zacks Rank.Studies have shown that stocks with the best growth features consistently outperform the market. 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.While there are numerous reasons why the stock of this housing materials maker is a great growth pick right now, we have highlighted three of the most important factors below:Earnings GrowthArguably nothing is more important than earnings growth, as surging profit levels is what most investors are after. For growth investors, double-digit earnings growth is highly preferable, as it is often perceived as an indication of strong prospects (and stock price gains) for the company under consideration.While the historical EPS growth rate for Quanex is 31.6%, investors should actually focus on the projected growth. The company's EPS is expected to grow 42.3% this year, crushing the industry average, which calls for EPS growth of 15.4%.Impressive Asset Utilization RatioGrowth investors often overlook asset utilization ratio, also known as sales-to-total-assets (S/TA) ratio, but it is an important feature of a real growth stock. This metric exhibits how efficiently a firm is utilizing its assets to generate sales.Right now, Quanex has an S/TA ratio of 1.65, which means that the company gets $1.65 in sales for each dollar in assets. Comparing this to the industry average of 0.92, 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 Quanex is well positioned from a sales growth perspective too. The company's sales are expected to grow 11% this year versus the industry average of 6.1%.Promising Earnings Estimate RevisionsSuperiority of a stock in terms of the metrics outlined above can be further validated by looking at the trend in earnings estimate revisions. A positive trend is of course favorable here. Empirical research shows that there is a strong correlation between trends in earnings estimate revisions and near-term stock price movements.There have been upward revisions in current-year earnings estimates for Quanex. The Zacks Consensus Estimate for the current year has surged 6% over the past month.Bottom LineQuanex has not only earned a Growth Score of B based on a number of factors, including the ones discussed above, but it also carries a Zacks Rank #2 because of the positive earnings estimate revisions.You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.This combination indicates that Quanex is a potential outperformer and a solid choice for growth investors.
