This study investigates the reaction of investors to the announcement of firms included in BIST Sustainability Index. Stock returns of BIST 50 firms, which are also constituents of BIST Sustainability Index, with those of BIST 50 firms that could not qualify for inclusion in BIST Sustainability Index, are compared. Based on mean/median tests, no significant difference between various returns of two groups of firms is found. Except for interval 0 to +4 days, the findings of event study indicates no significant abnormal returns for BIST Sustainability Index Constituents in the event window of 10 days surrounding the announcement day, but indicates significant positive cumulative abnormal returns for intervals 0 to +4 days, 0 to +5 days, 0 to +7 days, 0 to +8 days, 0 to +9 days and 0 to +10 days, which is an indication that investors valued the BIST Sustainability Index Constituents a few days after the announcement by investing in the stocks of these firms.

Increasing COVID-19 cases has not only impacted health and day-to-day lives of people, but it has also had a material effect on India’s economic growth. Stock returns of various sectors are evidence of a country’s stagnated growth but the healthcare and pharmaceutical sector might be affected in a different manner. The purpose of this paper is to find out how has this pandemic has impacted the healthcare and pharma stocks. Daily closing prices of sector specific indexes for 233 days ranging from 15 May 2019 to 24 April 2020 have been taken to compare different sectors with our test sector, on the basis of different criteria. This study has applied the widely used event study methodology on our test sector; calculated abnormal returns, cumulative abnormal returns and also tested their significance. Event study approach suggests that there have been significant abnormal returns and cumulative abnormal returns in our test sector (healthcare and pharmaceutical sector) over the event window, though while comparing it with other sectors through another econometric model, the returns are not statistically significant and do not explicitly indicate the same.

Not so long ago, ‘product recalls’ in the Indian automobile sector were a novelty. The defective vehicles were repaired as part of the after-sales service. In the absence of a strong regulatory framework, the manufacturers were under no obligation to proactively initiate product recalls. The introduction of a voluntary code on product recalls by the Society of Indian Automobile Manufacturers (SIAM) in 2012 and introduction/amendments in the existing legal regimen of the country in recent years have led companies to take more than just baby steps towards product recalls. Product recalls are a case of management failure. There is a need for gauging the impact of this failure on the stock price of the manufacturers, especially in the Indian context where the recall phenomenon is poised to gain further momentum. The event study methodology is a widely used approach to assess the impact of a particular event/announcement on the stock price. This methodology was used in the present study to gauge whether abnormal stock returns accrued to the manufacturers during 13 product recall announcements made in the Indian automobile sector between 1 January 2010 and 31 December 2015. The study found that product recall announcements generated small and statistically insignificant cumulative abnormal returns (CAR) of –0.02 per cent in the (–1, +1) event window, 0.92 per cent in the (–2, +2) event window and 1.70 per cent in the (–5, +5) event window. The study found no substantial or statistically significant difference in the CAR generated during big recalls and small recalls. Furthermore, the study found little evidence that CAR generated during recalls where defective component(s) in the vehicle were repaired is positive as compared to CAR generated when such component(s) were replaced.

Purpose This study Investigates Shareholders' value adjustment in response to financial institutions (FIs) merger announcements in the immediate event window and in the extended event window. This study also investigates accounting measures performance, comparison of post-merger to pre-merger, including several cash flow measures and not just profitability measures, as the empirical literature review suggests. Finally, the authors examine FIs mergers orientations of diversification and focus create more value for shareholders (in the immediate announcement window and several months afterward) and/or generates better cash flows, profitability and less credit risk. Design/methodology/approach This study examines FIs merger effect on bidders’ shareholder’s value and on their observed performance. This examination deploys three techniques simultaneously: a) an event study analysis, to estimate and calculate abnormal returns (ARs) and cumulative abnormal returns (CARs) in the narrow windows of the merger announcement, b) buy and hold event study analysis, to estimate ARs in the wider window of the event, +50 to +230 days after the merger announcement and c) an observed performance analysis, of financial and capital efficiency measures before and after the merger announcement; return on equity, liquidity, cost to income ratio, capital to total assets ratio, net loans to total loans, credit risk, loans to deposits ratio, other expenses and total assets, economic value addition, weighted average cost of capital and return on invested capital. Deal criteria of value, mega-deals, strategic orientation (as in Ansoff (1980) growth strategies), acquiring bank size and payment method are set as individually as control variables. Findings Results show that FIs mergers destroy share value for the bidding firms pursuing a market penetration strategy. Market development and product development strategies enable shareholders’ value creation in short and long horizons. Diversification strategies do not influence bidding shareholders’ value. Local bank to bank mergers create shareholders’ value and enhance liquidity and economic value in the short run. Bank to bank cross border mergers create value for bidders’ in the long term but are associated with high costs and higher risks. Originality/value A significant advancement over the current literature is in assessing mergers, not only for bank bidders but also for the three pillars FIs of the financial sector; banks, real-estate companies and investment companies mergers. It is an improvement over current finance literature because it deploys two different strategies in the analysis. At a univariate level, shareholder value creation and market reaction to merger announcements are examined over short (−5 or +5 days) and long (+230 days) windows of the event. Followed by regressing, the resultant CARs and BHARs over financial performance variables at the multivariate level.

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.

The study explores the correlation between the immediate and the longer-term stock returns following large daily price moves. Following the previous literature, which documents a tendency for price reversals after initial large price moves, I suggest that if a large stock price move is immediately followed by a short-term price drift, then it may indicate that the company-specific shock is more completely incorporated in the stock price, significantly increasing the probability of subsequent longer-term price reversal. Analyzing a vast sample of large stock price moves, I document that negative (positive) longer-term stock price reversals after large price increases (decreases) are significantly more pronounced if the latter are immediately followed by relatively high (low) short-term cumulative abnormal returns, that is, by short-term price drifts. The effect remains significant after accounting for additional company-specific (size, market model beta, historical, or conditional volatility) and event-specific (stock’s return and trading volume on the event day) factors.

The decade of the 1880s was a turbulent period for the French Third Republic. Corruption scandals that discredited republican parties and a lacklustre economic performance after the Paris Bourse crash of 1882 gave rise to widespread public disenchantment with the republican political elites. The rise of the Boulangist movement was the most representative example of this disillusionment. In 1887, Georges Boulanger, an army general and former minister of war, began orchestrating a populist mass campaign against the ruling republicans and the parliamentary regime. His political agitation, supported by a heterogeneous coalition of socialists, radicals and royalists, reached a climax in January 1889, when, after winning a Paris by-election, he had an opportunity to stage acoup d’état, which did not materialise. To understand whether French investors perceived the Boulangist campaign as a real threat to their interests, I use an original dataset of daily stock prices to analyse the effect of the January 1889 by-election on the value of politically connected firms listed on the Paris Bourse. The results show that firms with links to the republican parties experienced positive cumulative abnormal returns after Boulanger's refusal to stage the coup, while there was no effect on firms connected to the royalist parties or with no political ties. These findings suggest that French investors reacted positively to the prospective subsiding of the Boulangist movement.

The present study seeks to critically evaluate the most extensively employed technique – event study methodology, employed to capture the returns generated from M&A events on the wealth status of shareholders. Notwithstanding the popularity of the technique, authors in this paper argue that conceptual bases on which the methodology is founded is flawed. In the light of the extensive limitations attributable to event study methodology, there exists an urgent need to suggest improvement in the conceptual framework of the traditional method capable of lending application to capture the wealth effects of M&A events. The authors believe that application of such a modified approach will be much more salvageable as the results derived therefrom will command greater credibility as well as reliability. In order to highlight the inherent limitation of the event study approach, the authors have used the sample of Indian Banking M&A events retrieved from the M&A data available at etintelligence.com . Given the conceptual flaws of the event study approach, the authors argue that researchers must exercise great caution while commenting on the t-statistic observed for CAR (Cumulative Abnormal Returns) values as the statistical insignificance could be arising more out of the conceptual deficiency of the event study approach than pointing towards the neutral impact of an M&A event on the wealth status of the shareholders.

This paper investigates the impact of monetary policy committee decisions of the Central Bank of the Republic of Turkey on the stock returns of the deposit banks listed in Borsa Istanbul Banks Index (XBANK). The cumulative abnormal returns of the banks are calculated for 2008 and 2012. We report that the monetary policy announcements affect cumulative abnormal returns of the deposits banks both in 2008 and 2012. Since the announcement of the monetary policy decisions created abnormal returns, we conclude that the market does not have semi-strong form efficiency.
