Background

One of the most frequently cited market anomalies relates to a price drift after earnings announcements (also known as post-earnings announcement drift (PEAD)). Ball and Brown (1968) were the first to note that the cumulative abnormal returns of firms which report good (bad) news on their earnings are inclined to drift upwards (downwards) following their earnings announcements. Lending credence to this notion, Foster, Olsen and Shevlin (1984) consider a period of 60 days after earnings announcements and document robust empirical evidence regarding the existence of post-earnings announcement drifts.

As an explanation to the phenomenon of post-earnings announcement drifts,Joy, Litzenberger and McEnally (1977) suggest that market participants initially underreact to newly released information related to earnings and will gradually impound the correction of their previous beliefs into future stock prices. An alternative explanation suggests that a post-earnings announcement drift is a result of the misspecified capital asset pricing model (CAPM) employed to calculate abnormal returns (Ball, 1978). If this is the case, such abnormal returns are nothing more than fair compensation for risk that is priced but not captured by the CAPM. In light of the limitations of CAPM-related abnormal returns, Watts (1978) implements methods to mitigate the shortcomings of the CAPM and still document significant abnormal returns after earnings announcements. Providing support to the delayed response to information argument, Bernand and Thomas (1989, 1990) show that asset prices fail to capture information implied by the current earnings about future earnings.

This assignment is designed to let you investigate a post-earnings announcement drift using market data of Fortescue Metals Group Ltd (ASX Code: FMG).

Data

On the Canvas page for this course, there are two datasets you will need to use for this assignment. Their details are as follows:

  1. FMG_QEarnings: This dataset contains data on quarterly earnings of Fortescue Metals Group Ltd over 20 quarters starting from June 30, 2014 to March 31, 2019.

  1. ASX_DailyReturns: This dataset contains data on S&P/ASX200 daily returns over the period from April 1, 2019 to August 30, 2019.

Please note that you will need to collect additional data from FACTSET to complete this assignment. Please contact your course coordinator if you dont have access to FACTSET by the end of week 6.

Due to copyright issue, please make sure that two datasets mentioned above are not distributed outside the University of Newcastle.
