The Zacks Rank Explained: How to Find Strong Buy Construction Stocks

Enter the Zacks Rank.

What is the Zacks Rank?

A unique, proprietary stock-rating model, the Zacks Rank uses earnings estimate revisions, or changes to a company's earnings expectations, to help investors create 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.

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 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.

Retail investors who get in at the first sign of upward revisions have a distinct advantage over larger investors since it can often take weeks, if not months, for an institutional investor to build a position. They'll also benefit from the expected institutional buying that could 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 Emcor Group (EME), which was added to the Zacks Rank #1 list on August 4, 2026.

EMCOR Group is a provider of mechanical and electrical construction, industrial and energy infrastructure, and building services for a diverse range of businesses. The company serves commercial, industrial, utility and institutional clients in the United States. It provides planning, installation, operation, maintenance and protection services for building systems and critical infrastructure. As of June 30, 2026, EMCOR had about 47,700 employees.

Five analysts revised their earnings estimate upwards in the last 60 days for fiscal 2026. The Zacks Consensus Estimate has increased $3.67 to $33.04 per share. EME boasts an average earnings surprise of 12.2%.

Earnings are forecasted to see growth of 27.7% for the current fiscal year, and sales are expected to increase 19.6%.

EME has been moving higher over the past four weeks as well, up 6.7% compared to the S&P 500's gain of 3.5%.

Bottom Line

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