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. However, it isn't easy to find a great growth stock.

By their very nature, these stocks carry above-average risk and volatility. Moreover, if a company's growth story is over or nearing its end, betting on it could lead to significant loss.

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.

Arcosa (ACA) is on the list of such stocks currently recommended by our proprietary system. In addition to a favorable Growth Score, it 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 provider of infrastructure-related products and services 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 Arcosa is 5.5%, investors should actually focus on the projected growth. The company's EPS is expected to grow 10.5% this year, crushing the industry average, which calls for EPS growth of 10%.

Cash Flow Growth

Cash is the lifeblood of any business, but higher-than-average cash flow growth is more beneficial and important for growth-oriented companies than for mature companies. That's because, high cash accumulation enables these companies to undertake new projects without raising expensive outside funds.

Right now, year-over-year cash flow growth for Arcosa is 21.7%, which is higher than many of its peers. In fact, the rate compares to the industry average of 1.9%.

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 15.2% over the past 3-5 years versus the industry average of 7.2%.
