Standardized Unexpected Earnings

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.

So, as we delve deeper into the world of finance, let’s keep in mind the significant role of the earnings surprise prediction model. Stocks with positive earnings surprises tend to drift upward following the earnings announcement. Similarly, stocks with negative earnings surprises tend to drift downward after the announcement. This research is interesting, and the author provides very compelling evidence that suppliers’ returns are somewhat slow to react to key customers’ unexpected earnings news. It may be interesting to test this issue from another angle by examining the impact of suppliers’ earnings announcements on customers’ abnormal returns.

Conclusion and Future Work

According to the Journal of Behavioral and Experimental Finance by Josef Fink, high concentrations of institutional ownership can impede price adjustment. Trading frictions like transaction costs or liquidity are positively related to Post Earnings Announcement Drift. They can be direct transaction costs (bid-ask spreads, commissions) and indirect transaction costs (illiquidity, market impact costs). It is debatable whether such frictions allow for profitable arbitrage opportunities, depending on trading strategy specifications and risk factors. In the semi-strong form of market efficiency, all the publicly available information regarding the firms must be reflected already in the stock price.

Standardised unexpected earnings definition

Unexpected earnings are an important component in the accounting/financial industry because of their potential significance for investors. 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. Bartosiak also suggests investors look for stocks about which they can get an earnings tip-off even before the actual announcement. Purchasing these shares just before the official announcement could allow investors to enjoy gains of 10%-20% when the official earnings surprise is revealed. Based on how the market receives a company’s earnings report, there could be large price swings, thus impacting large price swings.

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”.

SERIAL CORRELATION COEFFICIENT OF SUEs

In market efficiency literature, one frequently discussed topic is the anomalous behavior of stock returns following earnings announcements. Instead, many studies report evidence that the direction and magnitude of returns in the post-earnings announcement period are positively correlated with the direction and magnitude of the unexpected component in the earnings releases. This observed phenomenon is consistent with suggestions that the capital market is inefficient. The relations between the SUE phenomenon and firm risk, the appropriateness of the earnings expectations model, and the role of transaction costs are also investigated. The SUE phenomenon is not attributable to inappropriate risk adjustment, use of the “wrong” earnings expectations model, or ignoring transaction costs.

Empirical Evidence of Post Earnings Announcement Drift Performance

While murky earnings outlooks add a whole new dimension of risk, they can also open doors for positive surprises. This study is based upon a sampleof the U.S. tech firms with fiscal year ending in March, June, September orDecember compiled in I/B/E/S History database for the period 1994 � 2000. Toeliminate firms with inactive trading, the sample includes only those firmsfollowed by at least three financial analysts.

What Causes Unexpected Earnings?

The study demonstrates that this trading strategy is most effective when fewer rather Standardized Unexpected Earnings In The U S Technology Sector than more financial analysts follow the firms. Two cumulative abnormal return windows of a supplier’s returns—a 3-day window and a 60-day window—are regressed on the customer’s standardized unexpected earnings (SUE). SUE is a ranked variable that essentially measures a customer’s actual reported earnings per share (EPS) minus the median of the analysts’ forecasted EPS.

• A strategy that buys stocks with a positive surprise and sells stocks with a negative surprise generally generates alpha.

Brown and Jeong (1998) showthat an earnings surprise predictor is effective in selecting stocks fromS&P 500 firms. Dische and Zimmermann (1999) report that abnormal returnscan be earned from the portfolio of the Swiss stocks exhibiting the mostpositive earnings revision. Conroy, Eades and Harris (2000) find that stockprices are significantly affected by earnings surprises in Japan. Hsu (2001) demonstrates that it isprofitable to take a long position in the portfolios with the highest earningssurprises and a short position in the portfolios with the lowest earningssurprises in the Asia/Pacific equity market.
