The Impact

Purpose – The purpose of this paper is to investigate how the announcement and implementation of short sales and margin trading regulation affects Chinese stock returns and trading volume. On 31 March 2010, the Chinese regulators launched a pilot programme, allowing short sales and margin trading for 50 Shanghai Stock Exchange and 40 Shenzhen Stock Exchange stocks. Design/methodology/approach – This paper uses an event study approach to compare market model abnormal returns (ARs) of the pilot firms with two distinct matched firm samples. A volume event study is also conducted to examine abnormal trading activity surrounding the key events in the pilot stocks. Findings – Negative ARs follow both the announcement and implementation of short selling and margin trading. This suggests the negative impact of short sales dominates the positive impact of margin trading on an average. Volume also declines, which is consistent with uninformed investors’ seeking to avoid trading against informed traders. Originality/value – The paper appears to be the first to address the impact of both the announcement and implementation of short selling and margin trading rule changes on returns and liquidity using individual stock data.

First Time

Purpose This paper aims to investigate the impact of qualified audit opinions on the returns of stocks listed at Amman Stock Exchange (ASE) after the introduction of the recent amendments by the International Auditing and Assurance Standard Board (IAASB) on audits reporting and conclusions. It further investigates if results differ between first time qualified and sequenced qualifications, and between plain qualified opinion and qualifications with going concern. Design/methodology/approach Audit opinions’ announcements and stock returns data are collected from companies’ annual reports for the fiscal years 2016 to 2019 while stock returns are computed from stock closing prices published at ASE website. The authors apply the event study approach and use the market model to calculate normal returns. Cumulative abnormal returns (CARs) and average abnormal returns (AARs) are computed for all qualified audit opinions’ announcements. Findings The empirical evidence suggests that investors at ASE do not react to qualified audit opinions announcements. That is, the authors find an insignificant impact of qualified audit opinion announcements on stock returns using both CAR and AAR estimates. The results are robust to first time and sequenced qualifications, and for qualifications with going concern. Results are also robust to the use of risk adjusted market model. Research limitations/implications The insignificant impact of qualified audit opinions on stock returns have two potential conflicting research implications. First, the new amendments introduced to auditors’ report made them more informative and reduce the negative signals contained in the qualified opinions. That is, investors are now aware of the real causes of qualifications and not overreacting to the qualified opinion. Second, the documented insignificant impact confirms that ASE is not a semi-strong form efficient. Practical implications The apparent excessive use of qualifications should ring the bell on whether auditors misuse their power or companies are really in trouble. Hence, the Jordanian regulatory bodies need to warn auditors against the excessive use of qualifications on the one hand, and to raise the awareness of investors on the implications of auditors’ opinions on the other hand. Originality/value This study is innovative in twofold. First, it explores the impact of qualified audit opinions on stock returns after the introduction of new amendments by IAASB at ASE. In addition, it uses event study approach and distinguishes between first time qualified and sequenced qualifications, and between plain qualified opinion and qualifications with going concern. The results are consistent with efficient market theory and behavioral finance explanations.

The Impact

Purpose This paper aims to examine the impact of general elections on the stock returns of the politically connected group affiliated firms of Pakistan. Design/methodology/approach This study uses the market model to assess the impact of political connections (PCs) on abnormal stock returns, before and after election events. We have used share price data of non-financial firms of Pakistan for the years 2008-2013. Findings It has been found that behavior of cumulative average abnormal returns (CAAR) is significantly different for standalone and politically connected group affiliated firms. The results reveal that CAARs of politically connected group affiliated firms have experienced less deviation as compared to stand alone firms. Therefore, it is argued that politically connected group firms may reduce the impact of political uncertainty on stock returns in comparison to stand alone firms. Practical implications This study is helpful for policy regulators of Pakistan to devise appropriate policies to maintain a level playing field for politically connected and standalone firms. Originality/value This study provides a new dimension to understand the role and association of PCs and general elections with stock markets returns.

Disclosure Rules

Purpose The purpose of this study is to examine the effectiveness of financial market rules in protecting minorities. Design/methodology/approach The study compares two alternative disclosure rules on insider trading, namely, the market abuse directive (Directive 2004/72/EC), inspired from the United State (US) insider trading regulation enacted by the Sarbanes–Oxley act and the transparency directive enacted by the European (Directive 2004/109/EC) dealing with the crossing of the shareholding threshold. To investigate which one is more effective in signaling reserved information, and thus in reducing information asymmetry, the authors run an event study on the French context, where both regulations are adopted. The data were hand collected from the French stock exchange securities commissions during the two years following the implementation of the two regulations in 2004. The final sample consists of 363 insiders trading and 35 crossing shareholding thresholds for 10 top French firms during the period 2006-2007. Findings The results show that the French market reacts significantly to insider trading, but poorly to the crossing shareholding thresholds. Abnormal returns are greater after insider purchases than after crossing up thresholds. These findings support the superiority of the insider disclosure regulation, as it has better information content and provides better protection to minorities. Research limitations/implications The study contributes to the corporate governance literature by comparing two disclosure-trading policies. The authors conclude that regulation of disclosure of insider trading along the lines of US disclosure rules is more informative to the market and thus more relevant and important than disclosure of cross-threshold trades. Practical implications The study contributes to the corporate governance literature by comparing two disclosure-trading policies. The authors conclude that regulation of disclosure of insider trading along the lines of US disclosure rules is more informative to the market and thus more relevant and important than disclosure of cross-threshold trades. This finding can be helpful for the securities lawmakers and regulators in the process of insider trading law enforcement. Originality/value Previous researchers approached the question of insider trading focusing on the identity of insiders. In the research, the authors address the question from another perspective, namely, the crossing of thresholds. Another methodological contribution of the study is the use of a market model that incorporates GARCH (generalized autoregressive conditional heteroskedastic) effect and time-varying systematic risk parameter (β), which is recommended to tackle the classical event study problem of detecting the exact timing of the event.

This study examines the reaction of stock returns to acquisition news. A data of 51 observations of acquiring companies with publicly traded shares on the London Stock Exchange (FTSE100) is used over a period, from July 2012 to May 2013 with an estimation period [-100, -10] and test period [-5, +5]. The market model is applied here in order to predict future stock returns and the use of the simple regression to get the parameters of the regression equation. With this a test statistics obtained on average, is significantly positive and greater than the critical value. Therefore, the event of acquisition does appear to be related significantly to the abnormal returns and the null hypothesis being rejected.

The Impact

A stock split is when a company’s outstanding shares are divided into multiple shares by issuing more shares to current shareholders without eroding their stake’s value. The company typically takes these actions to increase liquidity and marketability, lower stock prices, attract new investors and so on. The purpose of this study is to examine the impact of stock splits on the stock returns during the study period. Companies listed on the Bombay Stock Exchange (BSE) and those included in the S&P BSE 500 Index are included in the stock split data. The study period covers 14 years, between 2008 and 2021. Market model event study methodology is being employed to analyze the average abnormal returns (AARs), cumulative abnormal returns (CARs) and cumulative AAR (CAARs) using an event window period consisting of 31 days ([Formula: see text]). The study is largely based on secondary information from the CMIE Prowess IQ Database and the official BSE website. The [Formula: see text]-test, mean and standard deviation were used to investigate the influence of stock split announcements on share prices and the performance of stock splits before and after the announcement. The study found that on ([Formula: see text]), ([Formula: see text]), ([Formula: see text]) and ([Formula: see text]) and on the day of the announcement ([Formula: see text]), the market reacted favorably with significant positive abnormal returns. On ([Formula: see text]) and ([Formula: see text]) days, however, there were significant negative abnormal returns. The null hypothesis is accepted as the CAR for the whole 31-day event window, which is 0.0221, with a [Formula: see text]-statistic of 1.692, which is insignificant.

The Impact

Purpose The relationship between short selling, market volatility and liquidity remains an object of intensive research. However, empirical evidence is yet to provide a conclusive elucidation of this relationship by examining aspects of market fragmentation in the form of different market settings, different timing and different stocks under coverage, among others. This paper aims to contribute to the debate by investigating the impact of short selling on market volatility and liquidity in the Athens Exchange (ATHEX) under three different periods of short sales restrictions. Design/methodology/approach Two hypotheses are tested using econometric methodologies (co-integration and Granger-causality tools). Findings The empirical results indicate that when short selling is allowed, aggregate stock returns are in the short-term more volatile, but the liquidity of the market is not significantly affected. This might be the result of significant imbalances between supply and demand of stock caused by short-selling restrictions, leading to market price fluctuations. Research limitations/implications The analysis of empirical evidence needs further expansion and association with institutional firm-level and country-level elements to provide a more comprehensive understanding of the impact of short selling on market volatility and liquidity. Practical implications Stock market regulation involving short-selling restrictions have different implications according to extent and degree of stringency of the restrictions as well as the market on which they are imposed. That is especially important for the assessment of the market impact of the recent European Union regulation on short selling that has been imposed upon all EU member-States alike. Social implications Financial regulation policy must balance the benefits and costs for retail investors of imposing short-selling restrictions on stock market trading. Originality/value First-time empirical evidence is provided on the impact of short selling regulations on market volatility and liquidity of ATHEX highlighting the potential effectiveness of regulation policy.

Purpose The purpose of this paper is to examine the impact of the Cypriot banking crisis in specific bank stocks’ prices traded in the Athens Stock Exchange. Design/methodology/approach In the present study, event study methodology has been used. The basis of the event study is to examine the returns derived from the stock prices of the relevant banks before March 15, 2013. Findings This study focuses on three banks, Bank of Cyprus, Cyprus Popular Bank and Piraeus Bank, and finds abnormal stock returns during the ten-day period before the event date (announcement of prohibition and put under suspension trading of all movable securities of Bank of Cyprus and Cyprus Popular Bank). Also, an interesting matter is that during the estimation period and in specific dates, such as October 18, 22 and 23, 2012, a high volume of stocks trading took place in Bank of Cyprus and Cyprus Popular Bank. Originality/value To the best of the author’s knowledge, this is the first study examining it.

Negative Effect

Purpose The purpose of this paper is to investigate the response of investors to the announcements on the inclusion and exclusion of companies from the FTSE-ASE 20 index. Design/methodology/approach Data on the inclusion and exclusion of companies from the FTSE-ASE 20 index in the period 2000-2012 were used. The authors performed an event study analysis using a constant return model and a market model. Two different measures of aggregated abnormal returns, namely the cumulating abnormal returns and the buy-and-hold abnormal return, were used in this investigation. Findings The results suggest that the exclusion of a company from the index has a significant negative effect on stock returns. Specifically, such a stock takes more than 15 days to recover. However, for a company’s inclusion in the index, the authors observe short-lived positive reactions on stock returns. Practical implications Capital market regulators and investors should find the policy implications of this paper meaningful. Investment strategies can be implemented on the basis of the news of exclusion from the index, which can lead to higher performance for investors. As far as authorities are concerned, the decision of inclusion and exclusion to the most significant stock index in the Greek market should be carefully considered because it creates financial instability for a significant time period. Originality/value By using a battery of parametric and non-parametric econometric tests, the existence of abnormal returns of the FTSE-ASE 20 index is explored over a long time period, including the recent financial crisis.

The Impact

Purpose – The purpose of this paper is to examine the impact of Broad-Based Black Economic Empowerment (BBBEE) on the risk and returns of listed and delisted property firms on the Johannesburg Stock Exchange (JSE). The study was investigated to understand the impact of Black Economic Empowerment (BEE) property sector charter and effect of government intervention on property listed markets. Design/methodology/approach – The study examines the performance trends of the listed and delisted property firms on the JSE from January 2006 to January 2012. The data were obtained from McGregor BFA database to compute the risk and return measures of the listed and delisted property firms. The study employs a capital asset pricing model (CAPM) to derive the alpha (outperformance) and beta (risk) to examine the trend amongst the BEE and non-BEE firms, Sharpe ratio was also employed as a measurement of performance. A comparative study is employed to analyse the risks and returns between listed property firms that are BEE compliant and BEE non-compliant. Findings – Results show that there exists differences in returns and risk between BEE-compliant firms and non-BEE-compliant firms. The study shows that BEE-compliant firms have higher returns than non-BEE firms and are less risky than non-BEE firms. By establishing this relationship, this possibly affects the investor’s decision to invest in BEE firms rather than non-BBBEE firms. This study can also assist the government in strategically adjusting the policy. Research limitations/implications – This study employs a CAPM which is a single-factor model. Further study could employ a multi-factor model. Practical implications – The results of this investigation, with the effects of BEE on returns, using annualized returns, the Sharpe ratio and alpha (outperformance), results show that BEE firms perform better than non-BEE firms. These results pose several implications for investors particularly when structuring their portfolios, further study would need to examine the role of BEE on stock returns in line with other factors that affect stock returns. The results in this study have several implications for government agencies, there may be the need to monitor the effect of the BEE policies on firm returns and re-calibrate policies accordingly. Originality/value – This study investigates the performance of listed property firms on the JSE which are BEE compliant. This is the first study to investigate listed property firms which are BEE compliant.
