How Has the Indonesian Stock Market Performed During Covid-19 Outbreaks?

This paper analyzes the stock market reaction towards the Covid-19 pandemic by using a sample of Indonesian listed firms. In general, we document a significant negative cumulative abnormal returns when the Indonesian President announces the first case of Covid-19 in Indonesia. This effect remains ten days (weaker) after the announcement. However, we only find a short-term effect on the finance industry. While the explanation is still unclear, the investors may observe that the economic impact on the finance industry may arise in the long-run.

The valuation effects of hotel mergers

This study aims to evaluate the merger effect of hotel mergers between 1981 and 2019 and assess which theoretical framework mergers in the lodging industry would conform. Previously, no work has been done about the nature of hotel mergers using the combined return, while this lack of thoroughness in assessing the motivation of those mergers has triggered different interpretations. The design of this study follows the traditional framework of an event study by assessing various types of cumulative abnormal returns around the announcement date. The key finding of this study suggests that the nature of hotel mergers strongly supports the synergy hypothesis. In order to explore the causal inferences of this result by bidder and target, an additional analysis was conducted by regressing the cumulative abnormal returns on accounting measures as well as merger- and hotel industry–specific variables. This panel data analysis showed that in a merger where both the bidder and target are affected, the amount of total debt, being engaged in the casino business, and whether the merger was involving a stock swap sent out positive signals to the market, whereby longer duration and higher deal value lifted the undervalued target.

How Sports Sponsorship Influences a Sponsor’s Financial Performance: A Case Study from the Korea Baseball Organization

This study aims to examine the effects of sponsorship on the sponsor’s financial performance. Th is study investigates return on sponsorship (ROS) with a quantitative analysis. Nexen Tire’s title sponsorship agreement with the Heroes baseball club in the Korea Baseball Organization (KBO) in 2010 is studied. The positive effect of sponsorship on the sponsor’s Tobin’s q is confirmed by comparing the non-sponsorship period (2000‒2009) with the sponsorship period (2010‒2018). It is also shown from an event study that the sponsor experiences negative abnormal stock returns on the news of the sponsorship agreement, though this was not found to be statistically significant. Still, when the sponsee enters the postseason, positive cumulative abnormal returns are observed, particularly significant 10 days before the postseason games. Th is study confirms the positive influence of sponsorship on the sponsor’s financial performance and, with evidence from South Korea, provides insight into Asian markets in need of research. Th e results suggest that 10 days before a postseason game would be an ideal time to leverage marketing and activate a sponsorship strategy.

Price and volume effects around Islamic index revisions: the case of DJIM-GCC

PurposeThis study explores the price and trading volume effects around the quarterly Dow Jones Islamic Market-GCC index (DJIM-GCC) revisions and investigates whether these reactions are driven by firms' fundamentals or by investors' perception of ethical screening.Design/methodology/approachThe authors adopt an event study methodology to analyze the price and volume effects of Islamic indices redefinitions.FindingsThe results exhibit a positive (negative) price reaction for added (deleted) stocks. The authors also document an asymmetric volume response for index additions and deletions. The multivariate analysis of the cumulative abnormal returns reveals that the documented market reaction around Islamic index revisions is mainly related to the compliance attribution (withdrawal).Originality/valueThe approach allows to separate the market reaction arising from changes in firms' fundamentals from that induced by investors' perception of the attribution or withdrawal of a compliance certification. Moreover, the focus on the GCC region, where countries share the same cultural traits and perceive Islamic law identically excludes any social effect that would influence the market reaction due to cultural differences between countries.

Daily abnormal returns and price effects in the “passion investments” market

This paper explores price effects in the “passion investments” market after days with abnormal returns. To do this, daily prices for stamps and diamonds over the periods 1999–2021 and 1989–2021 are analyzed. The following hypothesis is tested: One-day abnormal returns create stable patterns in price behavior on the next day. Statistic tests (t-test, ANOVA, Mann–Whitney U test, modified cumulative abnormal returns approach, regression analysis with dummy variables) confirm the presence of price patterns related to extreme returns: price fluctuations on the day after extreme returns are higher than returns on “normal” days. On the days after positive abnormal returns, the momentum effect is detected. Contrarian effect is typical for the days after negative abnormal returns. A trading strategy based on detected price effects showed the presence of exploitable profit opportunities. Results of this paper provide additional pieces of evidence in favor of inconsistencies between the efficient market hypothesis and practice and can be used by traders to generate extra profits in the “passion investments” market.

Limits of arbitrage and mispricing: evidence from mergers and acquisitions

PurposeThis paper examines the extent to which noise demand and limits of arbitrage affect the pricing of acquirer stocks both at the announcement period and over the longer horizon.Design/methodology/approachAn event study approach was adopted to measure announcement-period cumulative abnormal returns. Long-horizon returns are measured using buy-and-hold abnormal returns (BHARs), calendar time portfolios (CTPRs), and subsequent earnings announcement period abnormal returns. Main methodologies include ordinary least squared (OLS) regressions, Logit regressions, and portfolio analysis.Findings(1) Acquirer stocks with high idiosyncratic volatility (the proxy for the security level characteristic most directly associated with limits to arbitrage) earn higher announcement-period abnormal returns. (2) The return pattern reverses over the subsequent longer horizon, resembling news-driven transitory mispricing. (3) The mispricing is greater when deal and firm characteristics exacerbate the limits of arbitrage, and it weakens over time. (4) Transactions by higher idiosyncratic volatility acquirers are more likely to fail.Originality/valueLimits of arbitrage theory have been tested mostly in information-free circumstances. The findings in this paper extend the supporting evidence for limits of arbitrage explaining mispricing beyond the boundaries of information-free circumstances.

The Covid-19’s Impact on Stock Prices among Different Sectors - An Event Study Based on the Istanbul Stock Exchange Market

The Covid-19 pandemic has deeply affected our health and social life as well as the financial markets. Although the global economic effects of the coronavirus are not yet clear, it is observed that there is a reaction in the financial markets to the developments related to the pandemic. Studies show that the pandemic has strong impact on stock markets and increases uncertainty.

The Impact of Scandalous News in the Automobile Manufacture on Companies from the Same Industry: A Comparative Study on the Chinese and European Markets

This paper examines the effect of scandalous news on corporate reputation of rival firms from the same industry and investigates the effects’ differences in China and in Europe, providing evidence that scandalous news influences not only the target company itself, but also other companies from the industry. For this purpose, the paper uses the 2015 Volkswagen emissions scandal as a natural experiment. Volkswagen, BMW, Mercedes-Benz, Audi and Porsche were selected as sample companies. To measure reputational spillover effects, cumulative abnormal stock returns and sales growth of the sample companies are calculated and compared before and after the announcement of the scandal. The methodology adopted for estimating stock returns is the event study method, which measures the impact of a specific event on the value of a firm. Stock price data is collected from Bloomberg and used to calculate cumulative abnormal returns of the sample companies. Furthermore, difference-in-differences estimation is used to compare the sample companies’ sales growth before and after the scandal. Volkswagen, Audi, BMW and Mercedes-Benz are included in the treatment group, whereas 29 non-German car manufacturers were selected as the control group. The results show that overall rival companies were affected by the scandal, cumulative abnormal returns declined by 6% and 10% for BMW and Mercedes-Benz respectively, showing the contagion effect. However, the sales growths of these two manufacturers greatly increased, specifically on the Chinese market for Mercedes-Benz and on the European market for BMW, proving dominance of the competitive effect and differences of the reputational spillover effects across countries.

CORPORATE GOVERNANCE AND STOCK MARKET REACTION TO SEASONED EQUITY OFFERING ANNOUNCEMENT BY FIRMS IN NIGERIA

This study examined the effect of corporate governance variables of board independence, institutional ownership, managerial ownership, board size, and director expertise on the market reaction to seasoned equity offering (SEO) announcements by firms in the Nigerian stock market. The event study methodology was employed, and abnormal returns were computed using the market model. A total of 62 announcements by 38 firms listed on the Nigerian stock exchange from 1st January 2006 to 31st December 2016 were included in the analysis. The study recorded significant positive cumulative abnormal returns before and after the announcement day, and a significant negative cumulative abnormal return upon the announcement day of SEOs. Similarly, significant positive cumulative abnormal returns were recorded six months before the SEO announcement day and negative significant cumulative abnormal returns six, twelve, and twenty-four months after the announcements. Furthermore, there were significant cumulative abnormal returns upon SEO announcements for all the proxies of corporate governance assessed by the study. The implication of the findings of negative significant cumulative abnormal returns on the day of the announcement and beyond was consistent with previous arguments that firms issuing SEOs earn negative abnormal returns on the day of the announcement was the result of the information asymmetry between managers and investors. By contrast, the significant cumulative abnormal returns based on corporate governance suggested that corporate governance significantly impacted on SEO announcement returns in Nigeria. These findings suggest that policy makers should pay more attention to directors’ expertise, institutional ownership, board independence, and board size, as our results showed that investors might view them as dependable pointers of positive corporate information for the market, thus guaranteeing the best use of SEO proceeds.

IPO Intra Industry Effects on Peer Firm's Earnings, Composition and Stock Returns

The present study is conducted to see how an IPO event affects the existing firm's performance within the same industry. For this purpose, 88 IPO firms were examined from Pakistan Stock Exchange (PSX) from 1998-2016. IPO is examined from three major perspectives IPO proceeds, initial returns and time Lag between IPO listing date and IPO subscription. The study uses Buy and Hold Abnormal Returns (BHAR) and Cumulative Abnormal Returns (CAR) to calculate competitor's abnormal returns. To calculate the operating performance of competitors, the Wilcoxon significance test was applied. IPO intra-industry effects are significant in the long run, whereas insignificant results are shown in the short run. In addition, IPO proceeds and abnormal returns are significant but negatively related to competitors' stock returns (long term). Moreover, Herfindahl Hirschman Index (HHI) finds IPO improves competitiveness in the industry environment. This present study is an important one from an emerging economy perspective.
