Quarterly financial reports play a vital role on Wall Street, as they help investors see how a company has performed and what might be coming down the road in the near-term. And out of all of the metrics and results to consider, earnings is one of the most important.

We know earnings results are vital, but how a company performs compared to bottom line expectations can be even more important when it comes to stock prices, especially in the near-term. This means that investors might want to take advantage of these earnings surprises.

The ability to identify stocks that are likely to top quarterly earnings expectations can be profitable, but it's no simple task. Here at Zacks, our Earnings ESP filter helps make things easier.

The Zacks Earnings ESP, Explained

The Zacks Expected Surprise Prediction, or ESP, works by locking in on the most up-to-date analyst earnings revisions because they can be more accurate than estimates from weeks or even months before the actual release date. The thinking is pretty straightforward: analysts who provide earnings estimates closer to the report are likely to have more information.

The core of the ESP model is comparing the Most Accurate Estimate to the Zacks Consensus Estimate, where the resulting percentage difference between the two equals the Expected Surprise Prediction. The Zacks Rank is also factored into the ESP metric to better help find companies that appear poised to top their next bottom-line consensus estimate, which will hopefully help lift the stock price.

When we join a positive earnings ESP with a Zacks Rank #3 (Hold) or stronger, stocks posted a positive bottom-line surprise 70% of the time. Plus, this system saw investors produce roughly 28% annual returns on average, according to our 10 year backtest.

Most stocks, about 60%, fall into the #3 (Hold) category, and they are expected to perform in-line with the broader market. Stocks with a #2 (Buy) and #1 (Strong Buy) rating, or the top 15% and top 5% of stocks, respectively, should outperform the market, with Strong Buy stocks outperforming more than any other rank.

Should You Consider FedEx?

The final step today is to look at a stock that meets our ESP qualifications. FedEx (FDX Quick QuoteFDX - Free Report) earns a #3 (Hold) 30 days from its next quarterly earnings release on March 19, 2026, and its Most Accurate Estimate comes in at $4.14 a share.

FedEx's Earnings ESP sits at +0.49%, which, as explained above, is calculated by taking the percentage difference between the $4.14 Most Accurate Estimate and the Zacks Consensus Estimate of $4.12. FDX is also part of a large group of stocks that boast a positive ESP. Make sure to utilize our Earnings ESP Filter to uncover the best stocks to buy or sell before they've reported.

FDX is just one of a large group of Transportation stocks with a positive ESP figure. Westinghouse Air Brake Technologies (WAB Quick QuoteWAB - Free Report) is another qualifying stock you may want to consider.

Slated to report earnings on April 22, 2026, Westinghouse Air Brake Technologies holds a #2 (Buy) ranking on the Zacks Rank, and its Most Accurate Estimate is $2.59 a share 64 days from its next quarterly update.

Westinghouse Air Brake Technologies' Earnings ESP figure currently stands at +0.39% after taking the percentage difference between its Most Accurate Estimate and its Zacks Consensus Estimate of $2.58.

Because both stocks hold a positive Earnings ESP, FDX and WAB could potentially post earnings beats in their next reports.
