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 growth stock that can live up to its true potential can be a tough task.

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.

Fortinet (FTNT) 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 returns are even better for stocks that possess the combination of a Growth Score of A or B and a Zacks Rank #1 (Strong Buy) or 2 (Buy).

Here are three of the most important factors that make the stock of this network security company a great growth pick right now.

Earnings Growth

Arguably 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 Fortinet is 42%, investors should actually focus on the projected growth. The company's EPS is expected to grow 33.6% this year, crushing the industry average, which calls for EPS growth of 30.1%.

Cash Flow Growth

While 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 Fortinet is 34.6%, which is higher than many of its peers. In fact, the rate compares to the industry average of -14.4%.

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 34.5% over the past 3-5 years versus the industry average of 15.2%.
