How to Boost Your Portfolio with Top Medical Stocks Set to Beat Earnings

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.

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.

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.

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.

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 CVS Health?

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. CVS Health (CVS) earns a #2 (Buy) right now and its Most Accurate Estimate sits at $1.55 a share, just 29 days from its upcoming earnings release on July 31, 2025.

CVS Health's Earnings ESP sits at +6.35%, which, as explained above, is calculated by taking the percentage difference between the $1.55 Most Accurate Estimate and the Zacks Consensus Estimate of $1.46. CVS is also part of a large group of stocks that boast a positive ESP. Make sure to utilize our Earnings ESP Filter to uncover the best stocks to buy or sell before they've reported.

CVS is part of a big group of Medical stocks that boast a positive ESP, and investors may want to take a look at Cardinal Health (CAH) as well.

Cardinal Health, which is readying to report earnings on August 13, 2025, sits at a Zacks Rank #2 (Buy) right now. It's Most Accurate Estimate is currently $2.04 a share, and CAH is 42 days out from its next earnings report.

The Zacks Consensus Estimate for Cardinal Health is $2.02, and when you take the percentage difference between that number and its Most Accurate Estimate, you get the Earnings ESP figure of +1.1%.

CVS and CAH's positive ESP metrics may signal that a positive earnings surprise for both stocks is on the horizon.
