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.

Even though momentum is a popular stock characteristic, it can be tough to define. Debate surrounding which are the best and worst metrics to focus on is lengthy, but the Zacks Momentum Style Score, part of the Zacks Style Scores, helps address this issue for us.

Below, we take a look at Deutsche Telekom AG (DTEGY), 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. Deutsche Telekom AG currently has a Zacks Rank of #1 (Strong 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 DTEGY is a promising momentum pick, let's examine some Momentum Style elements to see if this company 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 DTEGY, shares are up 3.28% over the past week while the Zacks Diversified Communication Services industry is up 1.15% over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 5.67% compares favorably with the industry's 0.51% performance as well.

While any stock can see its price increase, it takes a real winner to consistently beat the market. That is why looking at longer term price metrics -- such as performance over the past three months or year -- can be useful as well. Over the past quarter, shares of Deutsche Telekom AG have risen 18.63%, and are up 33.97% in the last year. In comparison, the S&P 500 has only moved 6.03% and 29.89%, respectively.
