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.

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 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.

Parker-Hannifin (PH) 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).

While there are numerous reasons why the stock of this maker of motion and control products is a great growth pick right now, we have highlighted three of the most important factors below:

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 Parker-Hannifin is 19.3%, 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 5.6%.

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 Parker-Hannifin is 20%, which is higher than many of its peers. In fact, the rate compares to the industry average of 13.5%.

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 14% over the past 3-5 years versus the industry average of 9.1%.
