Standardized Unanticipated Earnings What is Standardized Unanticipated Earnings, Meaning, Definition
“In fact, our work shows that stocks that beat consensus earnings or revenue expectations tend to outperform stocks that missed expectations over the subsequent one and three months, and this holds true both among liquid and less liquid stocks,” Lerner says. A far better approach is to look for high-quality earnings, as well as revenue surprises, which tend to be the result of strong revenue growth. “Although revenue growth alone does not define a high-quality company, it is a strong indication that there is demand for its products or services,” Lerner says.
SERIAL CORRELATION COEFFICIENT OF SUEs
The sample universe consists ofroughly 270 tech firms in 1994, growing to 500 firms in 2000, resulting in 7966stock-quarter observations for the analysis. At the same time, most academic researchers focussed on the magnitude and direction of the surprise and the price changes immediately after the announcement. As we mentioned, Post Earnings Announcement Drift is an inefficiency that investors can capitalize on if they buy stocks with high earnings surprises and hold them for nearly two months. Although it captures the earnings surprises, it fails to capture the new information released around earnings announcement dates.
It is written based on a paper published in The Accounting Review by Foster, Olsen, and Shevlin (1984). Our implementation narrows down our universe to 1000 liquid assets based on daily trading volume and price, and the availability of fundamental data on the stocks in our data library. We calculate the unexpected earnings at the beginning of each month, standardize the unexpected earnings, go long on the top 5%, and rebalance the portfolio monthly. We observed a Sharpe ratio of 0.602 relative to SPY Sharpe of 0.43 using this implementation during the period of December 1, 2009 to September 1, 2019 in backtesting. A common belief among investors is that combining earnings and revenue surprises is most applicable to smaller companies—liquidity (i.e., how easy the stock is buy and sell quickly) being a key factor. Yet, in their analysis, the researchers found that post-announcement outperformance driven by earnings and revenue surprises tends to persist across all capitalization categories and trading-volume levels.

This study shows that earnings surprises are useful in identifying portfolios that yield excess returns in the U.S. tech sector. The tech portfolios with the most positive earnings surprises outperformed the tech portfolios with the most negative earnings surprises in terms of both mean and median returns in the U.S. stock market. The study demonstrates that arbitrage profits could be generated if investors bought (short sold) the tech stocks with the highest earnings surprises (the lowest) two or three months after the end of the quarter.
Earnings Surprise Research: Synthesis and Perspectives
- The “surprise” aspect of the earnings means that the price of a stock can spike up or fall dramatically over the course of a single day.
- They base these predictions on several factors such as previous financial reports, current market conditions, as well as the business or investment’s financial behavior.
- This article takes a deep look at the PEAD strategy, its evolution, and how investors can take advantage of the post-earnings drift while portfolio building.

- Before the earnings release, the investors set an expectation while the company prepares its forward-looking statement (guidance).
It is widespread for a stock price to witness a sharp rise or decline immediately after an earnings report. The tendency for a stock to shift by massive magnitude in a specific direction after an earnings report creates active trading opportunities is known as Post Earnings Announcement Drift. When the company reports earnings that are different from the analyst estimates, it’s called an Earnings surprise. A positive surprise mostly leads to a sharp rise in the company’s stock price, while a negative surprise leads to a rapid downslide. Studies have shown that positive unexpected earnings can lead to an immediate increase in a stock’s price. If it’s the opposite where actual earnings are lesser than expected earnings, then this is considered negative unexpected earnings.
That said, even with all these considerations, analysts can still make mistakes that result in unexpected earnings. Analysts rely on several factors, such as the business or investment’s historical financial performance, or the current market condition. For example, an action that causes a public scandal will negatively affect a business’s prospective earnings, leading to negative unexpected earnings. When a business or an investment generates an earnings amount that is very different from what was expected, then it has “unexpected earnings”.

Levis and Liodakis (2001) concludethat positive and negative earnings surprises have an asymmetrical effect onthe returns of low- and high-rated stocks in the U.K. The objective of thisstudy is to contribute to the literature by adding this missing piece. Thefocus is on the U.S. technology sector as it has attracted significant publicinterest in recent years. This paper first examines if a trading strategy onthe basis of earnings surprises worked in the U.S. tech sector. Then itinvestigates if the strategy worked better for firms Standardized Unexpected Earnings In The U S Technology Sector followed by fewer, ratherthan more financial analysts. Earnings surprise occurs when the firm’s reported earnings per share deviates from the street estimate.
It’s a different story for larger companies, where performance driven by revenue surprises tends to be higher in up markets. One of the most significant events that an investor looks forward to is the quarterly earnings announcement of a company. Earnings and revenue are the two primary benchmarks that help the market gauge their financial health and ascertain if they are on their path to progress. After the analyst obtains the data s/he needs, s/he employs various techniques such as mathematical and financial models to come up with a business or investment’s expected earnings.
This article takes a deep look at the PEAD strategy, its evolution, and how investors can take advantage of the post-earnings drift while portfolio building. They also consider how the current market affects the performance of the business or investment. A business decision may positively or negatively affect its prospect on earnings, which can result in a different earnings amount from what was expected. They base these predictions on several factors such as previous financial reports, current market conditions, as well as the business or investment’s financial behavior. Even with careful planning, sometimes the unexpected may occur which causes a business or investment to generate an earnings figure that is very far from its expected amount.
A New Take on the Earnings-Surprise Strategy
However, most academic research focuses on the magnitude and direction of the surprise, and immediate stock price changes following the announcement. Lerner and his team expand on this by looking at the quality and stability of earnings. Forecasting price/earnings can be tricky, which means that unexpected earnings may be the result of inaccurate analyst estimates. However, when unexpected earnings – positive or negative – are the direct result of the company’s actions, they may offer important insights to investors about the future trajectory of the company’s stock. Financial analysts make mathematical and financial models of a company’s earnings from other accounting periods.
The unprecedented nature of the global economic shutdown forced many companies to withdraw earnings guidance. Just 26% of companies in the Russell 1000 are now providing guidance, compared with 47% in 2019. And only 8% of companies in the Russell 2000 have shared guidance, down from 21% a year ago. Expected earnings, as the name suggests, are the earnings a company is anticipated to generate. The figure is determined by market analysts who study the company’s historical earnings.
Yet, researchers found that post-earnings announcement drift persists across all capitalization categories and trading-volume levels. However, the team also found that earnings-surprise outperformance was higher in small- and mid-cap stocks in bear markets. As for large-cap stocks, the performance led by revenue surprises tends to be higher during bull markets. Research by Ball in 1993 states that betas rise for firms with high unexpected earnings and decline for firms with low unexpected earnings. A rise or a fall in beta (or risk) results from the seemingly abnormal returns after earnings announcements. Also, the Post Earnings Announcement Drift was more intense in subsequent announcement windows.
