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.

But how do you find the right combination of stocks? Funding your retirement, your kids' college tuition, or your short- and long-term savings goals certainly requires significant returns.

Enter the Zacks Rank.

What is the Zacks Rank?

The Zacks Rank is a unique, proprietary stock-rating model that utilizes earnings estimate revisions to help investors build a winning portfolio.

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 one of these factors is given a raw score that's recalculated every night, and then compiled into the Zacks Rank. Using this data, stocks are classified into five groups, ranging from "Strong Buy" to "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.

In order to determine the fair value of a company and its shares, institutional investors design valuation models that focus on earnings and earnings estimates. Because if you raise earnings estimates, it then creates a higher fair value for a company and its stock price.

Institutional investors then act on these changes in earnings estimates, typically buying stocks with rising estimates and selling those with falling estimates; an increase in earnings estimates can translate into higher stock prices and bigger gains for the investor.

Since it can often take weeks, if not months, for an institutional investor to build a position (given their size), retail investors who get in at the first sign of upward earnings estimate 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 +25.41%.

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 Mosaic (MOS), which was added to the Zacks Rank #1 list on August 7, 2021.

Minnesota-based The Mosaic Company is a leading producer and marketer of concentrated phosphate and potash for the global agriculture industry. It was formed through the combination of the fertilizer businesses of agribusiness giant Cargill Incorporated and IMC Global Inc. Mosaic is the biggest integrated phosphate producer globally and is also among the four largest potash producers in the world.

Five analysts revised their earnings estimate upwards in the last 60 days for fiscal 2021. The Zacks Consensus Estimate has increased $1.50 to $4.86 per share. MOS boasts an average earnings surprise of 43%.

Earnings are expected to grow 471.8% for the current fiscal year, while revenue is projected to increase 43.9%.

Additionally, MOS has climbed higher over the past four weeks, gaining 17.6%. The S&P 500 is down 3.6% in comparison.

Bottom Line

With a #1 (Strong Buy) ranking, positive trend in earnings estimate revisions, and strong market momentum, Mosaic should be on investors' shortlist.
