Momentum investing revolves around the idea of following a stock's recent trend in either direction. In "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.

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. Ecopetrol currently has a Zacks Rank of #1 (Strong Buy).

In order to see if EC is a promising momentum pick, let's examine some Momentum Style elements to see if this oil and natural gas exploration 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 EC, shares are up 5.67% over the past week while the Zacks Oil and Gas - Integrated - International industry is up 3.64% over the same time period. Shares are looking quite well from a longer time frame too, as the monthly price change of 5.52% compares favorably with the industry's 0.38% performance as well.

Considering longer term price metrics, like performance over the last three months or year, can be advantageous as well. Shares of Ecopetrol have increased 12.47% over the past quarter, and have gained 103.32% in the last year. In comparison, the S&P 500 has only moved 3.41% and 16.58%, respectively.

Investors should also pay attention to EC'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. EC is currently averaging 1,487,071 shares for the last 20 days.

These revisions helped boost EC's consensus estimate, increasing from $1.85 to $2.41 in the past 60 days. Looking at the next fiscal year, 2 estimates have moved upwards while there have been no downward revisions in the same time period.

Taking into account all of these elements, it should come as no surprise that EC is a #1 (Strong Buy) stock with a Momentum Score of B. If you've been searching for a fresh pick that's set to rise in the near-term, make sure to keep Ecopetrol on your short list.
