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.

The earnings figure itself is key, of course, but a beat or miss on the bottom line can sometimes be just as, if not more, important. Therefore, investors should consider paying close attention to these earnings surprises, as a big beat can help a stock climb and vice versa.

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, or Expected Surprise Prediction, aims to find earnings surprises by focusing on the most recent analyst revisions. The basic premise is that if an analyst reevaluates their earnings estimate ahead of an earnings release, it means they likely have new information that could possibly be more accurate.

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.

In fact, when we combined a Zacks Rank #3 (Hold) or better and a positive Earnings ESP, stocks produced a positive surprise 70% of the time. Perhaps most importantly, using these parameters has helped produce 28.3% 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 RBC Bearings?

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. RBC Bearings (RBC Quick QuoteRBC - Free Report) holds a #2 (Buy) at the moment and its Most Accurate Estimate comes in at $3.50 a share 30 days away from its upcoming earnings release on May 15, 2026.

By taking the percentage difference between the $3.50 Most Accurate Estimate and the $3.31 Zacks Consensus Estimate, RBC Bearings has an Earnings ESP of +5.80%. Investors should also know that RBC 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.

RBC is part of a big group of Industrial Products stocks that boast a positive ESP, and investors may want to take a look at Deere (DE Quick QuoteDE - Free Report) as well.

Deere, which is readying to report earnings on May 21, 2026, sits at a Zacks Rank #3 (Hold) right now. Its Most Accurate Estimate is currently $6.16 a share, and DE is 36 days out from its next earnings report.

Deere's Earnings ESP figure currently stands at +6.24% after taking the percentage difference between its Most Accurate Estimate and its Zacks Consensus Estimate of $5.80.

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