Two factors often determine stock prices in the long run: earnings and interest rates. Investors can't control the latter, but they can focus on a company's earnings results every quarter.

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.

Now that we understand the basic idea, let's look at how the Expected Surprise Prediction works. The ESP is calculated by comparing the Most Accurate Estimate to the Zacks Consensus Estimate, with the percentage difference between the two giving us the Zacks ESP figure.

Bringing together a positive earnings ESP alongside a Zacks Rank #3 (Hold) or better has helped stocks report a positive earnings surprise 70% of the time. Furthermore, by using these parameters, investors have seen 28.3% annual returns on average, according to our 10 year backtest.

Stocks with a ranking of #3 (Hold), or 60% of all stocks covered by the Zacks Rank, are expected to perform in-line with the broader market. Stocks with rankings of #2 (Buy) and #1 (Strong Buy), 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 Alphabet?

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. Alphabet (GOOGL Quick QuoteGOOGL - Free Report) holds a #3 (Hold) at the moment and its Most Accurate Estimate comes in at $2.15 a share two days away from its upcoming earnings release on July 23, 2025.

GOOGL has an Earnings ESP figure of +0.63%, which, as explained above, is calculated by taking the percentage difference between the $2.15 Most Accurate Estimate and the Zacks Consensus Estimate of $2.14. Alphabet is one of a large database 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.

GOOGL is just one of a large group of Computer and Technology stocks with a positive ESP figure. Cisco Systems (CSCO Quick QuoteCSCO - Free Report) is another qualifying stock you may want to consider.

Slated to report earnings on August 13, 2025, Cisco Systems holds a #3 (Hold) ranking on the Zacks Rank, and its Most Accurate Estimate is $0.98 a share 23 days from its next quarterly update.

The Zacks Consensus Estimate for Cisco Systems is $0.97, and when you take the percentage difference between that number and its Most Accurate Estimate, you get the Earnings ESP figure of +0.69%.

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