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.

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.

Let's discuss some of the components of the Momentum Style Score for HOLX that show why this medical device maker 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's also helpful to compare a security to its industry; this can show investors the best companies in a particular area.

For HOLX, shares are up 1.61% over the past week while the Zacks Medical - Instruments industry is flat over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 14.16% compares favorably with the industry's 10.33% performance as well.

Considering longer term price metrics, like performance over the last three months or year, can be advantageous as well. Shares of Hologic have increased 2.92% over the past quarter, and have gained 2.63% in the last year. In comparison, the S&P 500 has only moved -0.71% and -2.3%, respectively.
