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 Marks and Spencer Group PLC (MAKSY), a company that currently holds a Momentum Style Score of A. 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. Marks and Spencer Group PLC 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.

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

For MAKSY, shares are up 2.58% over the past week while the Zacks Retail - Supermarkets industry is up 1.87% over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 9.94% compares favorably with the industry's 0.32% performance as well.

Considering longer term price metrics, like performance over the last three months or year, can be advantageous as well. Shares of Marks and Spencer Group PLC have increased 24.25% over the past quarter, and have gained 74.51% in the last year. On the other hand, the S&P 500 has only moved 4.26% and 36.7%, respectively.
