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 Helios Technologies (HLIO), 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. Helios Technologies 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.You can see the current list of Zacks #1 Rank Stocks here >>>Set to Beat the Market?In order to see if HLIO is a promising momentum pick, let's examine some Momentum Style elements to see if this maker of screw-in hydraulic cartridge valves and manifolds holds up.Looking at a stock's short-term price activity is a great way to gauge if it has momentum, since this can reflect both the current interest in a stock and if buyers or sellers have the upper hand at the moment. 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 HLIO, shares are up 2.04% over the past week while the Zacks Manufacturing - General Industrial 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 20.91% compares favorably with the industry's 0.11% 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. Shares of Helios Technologies have increased 33.81% over the past quarter, and have gained 111.34% in the last year. On the other hand, the S&P 500 has only moved 5.02% and 32.65%, respectively.Investors should also take note of HLIO'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, HLIO is averaging 113,916 shares for the last 20 days.Earnings OutlookThe 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 HLIO.Over the past two months, 3 earnings estimates moved higher compared to none lower for the full year. These revisions helped boost HLIO's consensus estimate, increasing from $3.82 to $4.08 in the past 60 days. Looking at the next fiscal year, 3 estimates have moved upwards while there have been no downward revisions in the same time period.Bottom LineGiven these factors, it shouldn't be surprising that HLIO 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 Helios Technologies on your short list.
