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.
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, 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.
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.
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.
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 Enphase Energy?
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. Enphase Energy (ENPH) earns a #3 (Hold) right now and its Most Accurate Estimate sits at $0.57 a share, just five days from its upcoming earnings release on February 3, 2026.
By taking the percentage difference between the $0.57 Most Accurate Estimate and the $0.54 Zacks Consensus Estimate, Enphase Energy has an Earnings ESP of +5.56%. Investors should also know that ENPH is one of a large group of stocks with positive ESPs.
