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.

Now that we know how important earnings and earnings surprises are, it's time to show investors how to take advantage of these events to boost their returns by utilizing the Zacks Earnings ESP filter.

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.

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 ANI Pharmaceuticals?

The final step today is to look at a stock that meets our ESP qualifications. ANI Pharmaceuticals (ANIP Quick QuoteANIP - Free Report) earns a #2 (Buy) seven days from its next quarterly earnings release on November 7, 2025, and its Most Accurate Estimate comes in at $1.92 a share.

By taking the percentage difference between the $1.92 Most Accurate Estimate and the $1.74 Zacks Consensus Estimate, ANI Pharmaceuticals has an Earnings ESP of +10.55%. Investors should also know that ANIP is one of a large group of stocks with positive ESPs. Make sure to utilize our Earnings ESP Filter to uncover the best stocks to buy or sell before they've reported.

ANIP is just one of a large group of Medical stocks with a positive ESP figure. Gilead Sciences (GILD Quick QuoteGILD - Free Report) is another qualifying stock you may want to consider.

Gilead Sciences, which is readying to report earnings on February 10, 2026, sits at a Zacks Rank #3 (Hold) right now. Its Most Accurate Estimate is currently $2.04 a share, and GILD is 102 days out from its next earnings report.

For Gilead Sciences, the percentage difference between its Most Accurate Estimate and its Zacks Consensus Estimate of $2.03 is +0.09%.

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