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.
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.
The core of the ESP model is comparing the Most Accurate Estimate to the Zacks Consensus Estimate, where the resulting percentage difference between the two equals the Expected Surprise Prediction. The Zacks Rank is also factored into the ESP metric to better help find companies that appear poised to top their next bottom-line consensus estimate, which will hopefully help lift the stock price.
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 #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 Rivian Automotive?
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. Rivian Automotive (RIVN) holds a #3 (Hold) at the moment and its Most Accurate Estimate comes in at -$0.57 a share 22 days away from its upcoming earnings release on July 30, 2026.
By taking the percentage difference between the -$0.57 Most Accurate Estimate and the -$0.67 Zacks Consensus Estimate, Rivian Automotive has an Earnings ESP of +15.24%. Investors should also know that RIVN 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.
RIVN is part of a big group of Auto, Tires and Trucks stocks that boast a positive ESP, and investors may want to take a look at Blue Bird (BLBD) as well.
Blue Bird, which is readying to report earnings on August 5, 2026, sits at a Zacks Rank #3 (Hold) right now. Its Most Accurate Estimate is currently $1.26 a share, and BLBD is 28 days out from its next earnings report.
The Zacks Consensus Estimate for Blue Bird is $1.22, and when you take the percentage difference between that number and its Most Accurate Estimate, you get the Earnings ESP figure of +3.00%.
RIVN and BLBD's positive ESP metrics may signal that a positive earnings surprise for both stocks is on the horizon.
