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.

Life and the stock market are both about expectations, and rising above what is expected is often rewarded, while falling short can come with negative consequences. Investors might want to try to capture stronger returns by finding positive 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 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.

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 Parsons?

Now that we understand what the ESP is and how beneficial it can be, let's dive into a stock that currently fits the bill. Parsons (PSN Quick QuotePSN - Free Report) earns a #3 (Hold) right now and its Most Accurate Estimate sits at $0.74 a share, just 13 days from its upcoming earnings release on November 5, 2025.

By taking the percentage difference between the $0.74 Most Accurate Estimate and the $0.72 Zacks Consensus Estimate, Parsons has an Earnings ESP of +2.49%. Investors should also know that PSN 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.

PSN is one of just a large database of Business Services stocks with positive ESPs. Another solid-looking stock is Visa (V Quick QuoteV - Free Report) .

Visa, which is readying to report earnings on October 28, 2025, sits at a Zacks Rank #3 (Hold) right now. Its Most Accurate Estimate is currently $3.07 a share, and V is five days out from its next earnings report.

The Zacks Consensus Estimate for Visa is $2.96, and when you take the percentage difference between that number and its Most Accurate Estimate, you get the Earnings ESP figure of +3.70%.

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