Momentum investing revolves around the idea of following a stock's recent trend in either direction. In the 'long' context, investors will be essentially be "buying high, but hoping to sell even higher." With 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 that way. 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 Ametek (AME Quick QuoteAME - Free Report) , which currently has a Momentum Style Score of B. We also discuss some of the main drivers of the Momentum Style Score, like price change and earnings estimate revisions.

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. Ametek 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.

Let's discuss some of the components of the Momentum Style Score for AME that show why this maker of electronic instruments and electromechanical devices shows promise as a solid momentum pick.

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 is also useful to compare a security to its industry, as this can help investors pinpoint the top companies in a particular area.

For AME, shares are up 1.69% over the past week while the Zacks Electronics - Testing Equipment industry is up 0.79% over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 10.66% compares favorably with the industry's 3.09% performance as well.

Considering longer term price metrics, like performance over the last three months or year, can be advantageous as well. Shares of Ametek have increased 17.1% over the past quarter, and have gained 36.32% in the last year. In comparison, the S&P 500 has only moved 7.61% and 19.88%, respectively.

Investors should also take note of AME'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. Right now, AME is averaging 1,179,498 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 AME.

Over the past two months, 7 earnings estimates moved higher compared to none lower for the full year. These revisions helped boost AME's consensus estimate, increasing from $4.10 to $4.13 in the past 60 days. Looking at the next fiscal year, 4 estimates have moved upwards while there have been 2 downward revisions in the same time period.

Bottom Line

Given these factors, it shouldn't be surprising that AME is a #2 (Buy) stock and boasts a Momentum Score of B. If you're looking for a fresh pick that's set to soar in the near-term, make sure to keep Ametek on your short list.
