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. 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.

General Motors (GM) 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 an automotive manufacturer 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 General Motors is 23%, investors should actually focus on the projected growth. The company's EPS is expected to grow 33% this year, crushing the industry average, which calls for EPS growth of 1%.

Impressive Asset Utilization Ratio

Growth investors often overlook asset utilization ratio, also known as sales-to-total-assets (S/TA) ratio, but it is an important feature of a real growth stock. This metric shows how efficiently a firm is utilizing its assets to generate sales.

Right now, General Motors has an S/TA ratio of 0.65, which means that the company gets $0.65 in sales for each dollar in assets. Comparing this to the industry average of 0.42, it can be said that the company is more efficient.

While the level of efficiency in generating sales matters a lot, so does the sales growth of a company. And General Motors is well positioned from a sales growth perspective too. The company's sales are expected to grow 4.4% this year versus the industry average of 0%.
