Whether you're a growth, value, income, or momentum-focused investor, building a successful investment portfolio takes skill, research, and a little bit of luck.
How do you find the right combination of stocks that will generate returns that could fund your retirement, or your kids' college tuition, or your short- and long-term savings goals?
Enter the Zacks Rank.
What is the Zacks Rank?
The Zacks Rank, which is a unique, proprietary stock-rating model, employs earnings estimate revisions, or changes to a company's earnings expectations, that makes building a winning portfolio easier.
There are four main factors behind the Zacks Rank: Agreement, Magnitude, Upside, and Surprise.
Agreement is the extent to which all brokerage analysts are revising their earnings estimates in the same direction. The greater the percentage of analysts revising their estimates higher, the better chance the stock will outperform.
Magnitude is the size of the recent change in the consensus estimate for the current and next fiscal years.
Upside is the difference between the most accurate estimate, which is calculated by Zacks, and the consensus estimate.
Surprise is made up of a company's last few quarters' earnings per share surprises; companies with a positive earnings surprise are more likely to beat expectations in the future.
Each factor is given a raw score, which is recalculated every night and compiled into the Zacks Rank. Utilizing this data, stocks are put into five different groups: Strong Buy, Buy, Hold, Sell, and Strong Sell.
The Power of Institutional Investors
The Zacks Rank also allows individual investors, or retail investors, to benefit from the power of institutional investors.
These professionals manage the trillions of dollars invested in hedge funds, mutual funds, and investment banks, and studies have shown that they can and do move the market because of the large amounts of money they invest with. Thus, the market tends to move in the same direction as institutional investors.
These investors are known for designing valuation models that focus on earnings and earnings expectations in order to figure out the fair value of a company and its shares. If earnings estimates are raised, it puts a higher value on a company.
Institutional investors will use these changes to help in their decision-making, typically buying stocks with rising estimates and selling those with falling estimates. Higher earnings expectations can translate into a rise in stock price and bigger gains for the investor.
Because it can take a long time for an institutional investor to build a position--sometimes weeks, if not months--retail investors who get in at the first sign of upward revisions have a distinct advantage over these larger investors, and can benefit from the expected institutional buying that will follow.
Not only can the Zacks Rank help you take advantage of trends in earnings estimate revisions, but it can also provide a way to get into stocks that are highly sought after by professionals.
How to Invest with the Zacks Rank
The Zacks Rank is known for transforming investment portfolios. In fact, a portfolio of Zacks Rank #1 (Strong Buy) stocks has beaten the market in 26 of the last 32 years, with an average annual return of +23.94%.
Moreover, stocks with a new #1 (Strong Buy) ranking have some of the biggest profit potential, while those that fell to a #4 (Sell) or #5 (Strong Sell) have some of the worst.
Let's take a look at Garmin (GRMN), which was added to the Zacks Rank #1 list on August 1, 2026. Garmin Ltd., based in Olathe, Kansas, is an original equipment manufacturer of navigation and communication equipment that incorporates global positioning system technology.
Three analysts revised their earnings estimate higher in the last 60 days for fiscal 2026, while the Zacks Consensus Estimate has increased $0.28 to $9.81 per share. GRMN also boasts an average earnings surprise of 13.5%.
Earnings are expected to grow 14.6% for the current fiscal year, while revenue is projected to increase 12.2%.
Additionally, GRMN has climbed higher over the past four weeks, gaining 22.4%. The S&P 500 is up 0.2% in comparison.
Bottom Line
With a #1 (Strong Buy) ranking, positive trend in earnings estimate revisions, and strong market momentum, Garmin should be on investors' shortlist.
