Momentum investing is all about the idea of following a stock's recent trend, which can be in either direction. In the 'long' context, investors will essentially be "buying high, but hoping to sell even higher." And for investors following this methodology, taking advantage of trends in a stock's price is key; once a stock establishes a course, it is more than likely to continue moving in that direction. The goal is that once a stock heads down a fixed path, it will lead to timely and profitable trades.

While many investors like to look for momentum in stocks, this can be very tough to define. There is a lot of debate surrounding which metrics are the best to focus on and which are poor quality indicators of future performance. The Zacks Momentum Style Score, part of the Zacks Style Scores, helps address this issue for us.

Below, we take a look at Westinghouse Air Brake Technologies (WAB), a company that currently holds a Momentum Style Score of B. We also talk about price change and earnings estimate revisions, two of the main aspects of the Momentum Style Score.

It's also important to note that Style Scores work as a complement to the Zacks Rank, our stock rating system that has an impressive track record of outperformance. Westinghouse Air Brake Technologies currently has a Zacks Rank of #2 (Buy). Our research shows that stocks rated Zacks Rank #1 (Strong Buy) and #2 (Buy) and Style Scores of A or B outperform the market over the following one-month period.

Set to Beat the Market?

In order to see if WAB is a promising momentum pick, let's examine some Momentum Style elements to see if this maker of parts for locomotives, subways and buses holds up.

A good momentum benchmark for a stock is to look at its short-term price activity, as this can reflect both current interest and if buyers or sellers currently have the upper hand. It's also helpful to compare a security to its industry; this can show investors the best companies in a particular area.

For WAB, shares are up 6.06% over the past week while the Zacks Transportation - Equipment and Leasing industry is up 6.06% over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 9.87% compares favorably with the industry's 5.24% performance as well.

While any stock can see a spike in price, it takes a real winner to consistently outperform the market. Shares of Westinghouse Air Brake Technologies have increased 15.1% over the past quarter, and have gained 70.23% in the last year. On the other hand, the S&P 500 has only moved 4.97% and 33.47%, respectively.

Investors should also pay attention to WAB's average 20-day trading volume. Volume is a useful item in many ways, and the 20-day average establishes a good price-to-volume baseline; a rising stock with above average volume is generally a bullish sign, whereas a declining stock on above average volume is typically bearish. WAB is currently averaging 1,003,137 shares for the last 20 days.

Earnings Outlook

The Zacks Momentum Style Score also takes into account trends in estimate revisions, in addition to price changes. Please note that estimate revision trends remain at the core of Zacks Rank as well. A nice path here can help show promise, and we have recently been seeing that with WAB.

Over the past two months, 2 earnings estimates moved higher compared to none lower for the full year. These revisions helped boost WAB's consensus estimate, increasing from $7.40 to $7.46 in the past 60 days. Looking at the next fiscal year, 2 estimates have moved upwards while there have been no downward revisions in the same time period.

Bottom Line

Taking into account all of these elements, it should come as no surprise that WAB is a #2 (Buy) stock with a Momentum Score of B. If you've been searching for a fresh pick that's set to rise in the near-term, make sure to keep Westinghouse Air Brake Technologies on your short list.
