Growth investors focus on stocks that are seeing above-average financial growth, as this feature helps these securities garner the market's attention and deliver solid returns. But finding a growth stock that can live up to its true potential can be a tough task.

That's because, these stocks usually carry above-average risk and volatility. In fact, betting on a stock for which the growth story is actually over or nearing its end could lead to significant loss.

However, 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, makes it pretty easy to find cutting-edge growth stocks.

ServiceNow (NOW) 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.

Research shows that stocks carrying the best growth features consistently beat 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 maker of software that automates companies' technology operations a great growth pick right now.

Earnings Growth

Earnings 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 ServiceNow is 52.7%, investors should actually focus on the projected growth. The company's EPS is expected to grow 28.6% this year, crushing the industry average, which calls for EPS growth of 6.7%.

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 ServiceNow is 33%, which is higher than many of its peers. In fact, the rate compares to the industry average of -13.4%.

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 33.5% over the past 3-5 years versus the industry average of 9.1%.
