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, 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.SiteOne Landscape (SITE) 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.Here are three of the most important factors that make the stock of this company a great growth pick right now.Earnings GrowthArguably nothing is more important than earnings growth, as surging profit levels is what most investors are after. 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 SiteOne Landscape is 38%, investors should actually focus on the projected growth. The company's EPS is expected to grow 77.2% this year, crushing the industry average, which calls for EPS growth of 53.1%.Cash Flow GrowthWhile cash is the lifeblood of any business, higher-than-average cash flow growth is more important and beneficial for growth-oriented companies than for mature companies. That's because, growth in cash flow enables these companies to expand their businesses without depending on expensive outside funds.Right now, year-over-year cash flow growth for SiteOne Landscape is 38.4%, which is higher than many of its peers. In fact, the rate compares to the industry average of -7.5%.While investors should actually consider the current cash flow growth, it's worth taking a look at the historical rate too for putting the current reading into proper perspective. The company's annualized cash flow growth rate has been 25% over the past 3-5 years versus the industry average of 2.7%.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.The current-year earnings estimates for SiteOne Landscape have been revising upward. The Zacks Consensus Estimate for the current year has surged 14% over the past month.Bottom LineSiteOne Landscape 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 positions SiteOne Landscape well for outperformance, so growth investors may want to bet on it.
