Wall Street watches a company's quarterly report closely to understand as much as possible about its recent performance and what to expect going forward. Of course, one figure often stands out among the rest: earnings.

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.

Hunting for 'earnings whispers' or companies poised to beat their quarterly earnings estimates is a somewhat common practice. But that doesn't make it easy. One way that has been proven to work is by using the Zacks Earnings ESP tool.

The Zacks Earnings ESP, Explained

The Zacks Earnings ESP is more formally known as the Expected Surprise Prediction, and it aims to grab the inside track on the latest analyst estimate revisions ahead of a company's report. The idea is relatively intuitive as a newer projection might be based on more complete information.

With this in mind, the Expected Surprise Prediction compares the Most Accurate Estimate (being the most recent) against the overall Zacks Consensus Estimate. The percentage difference provides the ESP figure. The system also utilizes our core Zacks Rank to provide a stronger system for identifying stocks that might beat their next quarterly earnings estimate and possibly see the stock price climb.

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.

Stocks with a #3 (Hold) ranking, which is most stocks covered at 60%, are expected to perform in-line with the broader market. But stocks that fall into the #2 (Buy) and #1 (Strong Buy) ranking, or the top 15% and top 5% of stocks, respectively, should outperform the market. Strong Buy stocks should outperform more than any other rank.

Should You Consider Walmart?

The last thing we will do today, now that we have a grasp on the ESP and how powerful of a tool it can be, is to quickly look at a qualifying stock. Walmart (WMT Quick QuoteWMT - Free Report) holds a #3 (Hold) at the moment and its Most Accurate Estimate comes in at $0.76 a share eight days away from its upcoming earnings release on August 21, 2025.

Walmart's Earnings ESP sits at +4.95%, which, as explained above, is calculated by taking the percentage difference between the $0.76 Most Accurate Estimate and the Zacks Consensus Estimate of $0.72. WMT 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.

WMT is part of a big group of Retail and Wholesale stocks that boast a positive ESP, and investors may want to take a look at Amazon (AMZN Quick QuoteAMZN - Free Report) as well.

Amazon, which is readying to report earnings on October 30, 2025, sits at a Zacks Rank #3 (Hold) right now. Its Most Accurate Estimate is currently $1.58 a share, and AMZN is 78 days out from its next earnings report.

The Zacks Consensus Estimate for Amazon is $1.56, and when you take the percentage difference between that number and its Most Accurate Estimate, you get the Earnings ESP figure of +1.43%.

WMT and AMZN's positive ESP figures tell us that both stocks have a good chance at beating analyst expectations in their next earnings report.
