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 Zscaler (ZS Quick QuoteZS - Free Report) , 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. Zscaler 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.

Let's discuss some of the components of the Momentum Style Score for ZS that show why this cloud-based information security provider 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 ZS, shares are up 4.92% over the past week while the Zacks Internet - Services 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 8.21% compares favorably with the industry's 0.94% performance as well.

While any stock can see a spike in price, it takes a real winner to consistently outperform the market. Shares of Zscaler have increased 13.27% over the past quarter, and have gained 34.99% in the last year. In comparison, the S&P 500 has only moved 7.78% and 27.35%, respectively.

Investors should also pay attention to ZS'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. ZS is currently averaging 1,882,136 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 ZS.

Over the past two months, 13 earnings estimates moved higher compared to none lower for the full year. These revisions helped boost ZS's consensus estimate, increasing from $2.73 to $2.99 in the past 60 days. Looking at the next fiscal year, 7 estimates have moved upwards while there have been 4 downward revisions in the same time period.

Bottom Line

Given these factors, it shouldn't be surprising that ZS is a #1 (Strong 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 Zscaler on your short list.
