First, we examine whether CAR can accurately represent investors’ reactions to earnings information. Due to the unique announcements disclosure mechanism in China, some companies are compelled to disclose the preliminary earnings by CSRC. About half of the listed companies opt to disclose the preliminary earnings before the end of February, then release the annual report around April. Although the preliminary earnings are not audited, they are usually seemed as an important reference to the actual earnings by investors with high accuracy 20. Therefore, we calculate the difference between the preliminary earnings and the actual earnings as the earnings correction (EPS_PUB), which be the proxy for earnings surprises for specified firms. We find that only when there are earnings shocks, there is a significant positive correlation between EPS_PUB and CAR, but when there is no earnings shock, the correlation is insignificant, and the coefficient of EPS_PUB declines by about 80%.
They combine insights from multiple financial analysts, offering a benchmark based on average earnings per share (EPS) estimates. When companies surpass these forecasts, stock prices typically rise, reflecting investor optimism. The economic rationale for using SUE is that earnings surprises are not immediately fully reflected in the stock price. This implies that investors can earn excess returns by buying stocks that have positive stock surprises. This behavior of stock prices drifting upward after a positive announcement is referred to as the post-earnings announcement drift.
What is Post Earnings Announcement Drift?
Interestingly, earnings surprises can significantly influence a company’s stock price, often leading to increased volatility in the market following the announcement. Consistent trends in EPS are crucial; companies that frequently report positive surprises typically see rising stock prices, capturing optimistic investor sentiment. Interestingly, a study found that companies with a solid EPS growth rate often lead their industry peers in overall market performance. This post implements a strategy that standardizes the unexpected earnings of stocks and trades the top 5% of those standardized stocks. 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.
- Standardized Unexpected Earnings, or SUE, provides insights into how actual earnings relate to consensus forecasts.
- When there is no earnings information shock in the window, CAR may be interfered by financial anomalies, and the measurement of investors’ response is biased, which cannot effective proxy for investors’ reactions to earnings correction.
- Always conduct your own research and consult with a licensed financial advisor before making any financial decisions.
- If you are a serious investor or finance professional, knowing and being able to interpret the various types of SEC filings will help you in making informed investment decisions.
Trading frictions
Interestingly, research shows that companies with positive SUE often experience stock price increases shortly after earnings announcements. Interestingly, companies with fewer analysts covering them often present clearer patterns, enhancing trading strategies around earnings surprises. Lastly, consider employing machine learning techniques, which can improve prediction accuracy by accounting for the quality of input data and shifting market dynamics.
SUE in Q and SUE in Q+4
Second, we explore the correlation between various measures of earnings surprises and revised market reaction (CAR_NEW). They find that FOM is the better measure of actual earnings surprises within the U.S. stock market. We find that ERROR is not significantly related to CAR_NEW, whereas FOM is positively related to CAR and CAR_NEW. Then, when we put all measures of earnings surprise together as explanatory variables, only FOM remains significantly positive. These results indicate that FOM is a better proxy than other measures and absorbs the most unexpected earnings information reflected by ERROR.
Excel Shortcuts PC Mac List of Excel Shortcuts Excel shortcuts – It may seem slower at first if you’re used to the mouse, but it’s worth the investment to take the time and… A company’s SUE score has nothing to do with the courtroom success of its lawyers. ☆The financial support of the Chicago Mercantile Exchange and the North Carolina Institute for Investments Research is gratefully acknowledged. Interestingly, research shows that a firm with less than five analysts covering it can see stock price movements twice as volatile compared to more widely followed firms. Standardized Unexpected Earnings, or SUE, provides insights into how actual earnings relate to consensus forecasts. By grasping these metrics, you can better predict how the market will react and make educated investment choices regarding earnings surprises. Expected earnings, as the name suggests, are the earnings a company is anticipated to generate.
How does EPS affect stock price?
Management’s discussion and analysis dig into specific reasons behind aspects of company growth or decline on the income statement, balance sheet, and statement of cash flows. The section breaks down growth drivers, risks, even pending litigation (often also in the footnotes section). Management also frequently uses the MD&A section to announce upcoming goals and approaches to new projects, along with any changes in the executive suite and/or key hires. CFA Institute Research and Policy Center is transforming research insights into actions that strengthen markets, advance ethics, and improve investor outcomes for the ultimate benefit of society. The Post Earnings Announcement Drift strategy is rather challenging to implement as it requires data collection and processing at a larger scale. Moreover, recent advancements in information processing technologies may also impact the magnitude of Post Earnings Announcement Drift exploitation.
The best scores are earned by companies that have hefty earnings and beat forecasts clustered within a tight range. In other words, the amount of unexpected earnings is scaled by a measure of the size of historical forecast errors. Brown 33 first discovered the financial anomaly known as the Post-Earnings Announcement Drift.

Finally, we update the next rebalance time to the beginning of the next calendar month. A�Stock transactions were made two monthsafter the end of the SUE quarter for the first three quarters and three monthsafter the end of the SUE quarter for the fourth quarter.
3. Effectiveness of different earnings surprises measures
The absolutevalue of SUE measures the degree of unexpected earnings and the sign of SUEindicates whether the unexpected earnings are above or below the consensusestimate. Standardized unexpected Earnings (SUE) is a momentum indicator that is positively related to subsequent stock returns. A popular investment strategy based on SUE is the post earnings announcement drift trading strategy.
Post Earnings Announcement Drift (PEAD)
The results are consistent with the previous section, only the coefficient of FOM is significantly positive, the coefficients of ERROR1 and ERROR2 are insignificant, suggesting FOM is a more accurate measurement of earnings surprises. While CAR struggles to discern the optimal earnings surprise estimate, CAR_NEW reinforces the assertion that FOM serves as the most efficient proxy for earnings surprises. Many investors believe that combining earnings and revenue surprises are primarily for smaller companies and liquid stocks. 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.
Understanding Earnings Surprises
The sample universe consists ofroughly 270 tech firms in 1994, growing to 500 firms in 2000, resulting in 7966stock-quarter observations for the analysis. There is a statistically significant positive relationship between CAR_NEW and EPS_PUB, but no correlation is observed between CAR and EPS_PUB, suggesting that CAR_NEW effectively corrects CAR influenced by financial anomalies. Therefore, CAR_NEW seems to be a better proxy for the investors’ reactions to earnings correction. The cumulative evidence of Martineau showed striking evidence that stock prices have become more efficient following earnings announcements.
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 followed by fewer, ratherthan more financial analysts.
- Contrary to what the efficient market hypothesis predicts, an earnings surprise does not lead to a full, instantaneous adjustment of stock prices, but to a slow, predictable drift.
- These results indicate that FOM is a better proxy than other measures and absorbs the most unexpected earnings information reflected by ERROR.
- The section breaks down growth drivers, risks, even pending litigation (often also in the footnotes section).
- The estimation period is the time taken by the analyst to forecast the expected earnings.
The mainstream literature employs event study method to investigate the relationship between earnings surprises and market reaction 3, 13. They examine a noticeable positive correlation exists between earnings surprises and cumulative abnormal return (CAR) around the earnings announcement. However, some studies have revealed the substantial influence of financial anomalies on individual stock returns around earnings announcement.
EPS indicates how much money a company makes for each share of its stock and is a widely used metric for estimating corporate value. A higher EPS indicates greater value because investors will pay more for a company’s shares if they think the company has higher profits relative to its share price. Our evidence largely rules out explanations based on flow and limits-of-arbitrage, but is more consistent with agency-induced preferences for stock characteristics that relate to poor long-run performance. standardized earnings surprise In order tocreate an accurate forecastof how a specific company’s stock will perform, an analyst must gather information from several sources.
Thus, we believe that CAR needs to be amended to eliminate the effects of financial anomalies, and we examine whether CAR can accurately represent investors’ reactions to earnings information. If the surprise element in the earnings announcement is positive, the stock prices move positively and vice versa. This means that the direction of the price drift can be predicted based on the magnitude of an earnings surprise. 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.
