Investors’ reaction to the release of public information : A cross-sectional study of the famous European football clubs from season 2002-2003 to season 2011-2012

Cosquer, Guénolé, Berthelmé, Jean-Eudes January 2013 (has links)
This study deals with market reaction to public information. The sample studied concerns six different famous European football clubs that are regularly involved in European competitions. These clubs are AS Roma from the Italian championship Calcio Serie A, FC Porto from the Portuguese championship Super Liga, Ajax Amsterdam from the Dutch championship Holland Casino Eredivisie, Galatasaray and Besiktas Istanbul from the Turkish championship Super Lig, and Celtic Glasgow from the Scottish championship Premier League.               Palomino et al. (2009) is the main source of inspiration for this study. Most of the findings are in lines with their results. There are two main contributions in this research. Firstly, our sample is composed by clubs from 5 different European countries: Italy, Scotland, Turkey, Portugal and Netherlands. Secondly, the ten years period of the study includes the financial crisis period. The results obtained for the financial crisis period have contaminated most of our results, justifying the choice to focus mainly on the results of the period 2002-2012 without the 2007-2009 period, which is the period associated to the financial crisis.               This research is divided into four parts. We firstly find evidence that the release of public information during the on-season has more influence than the one of the off-season. Indeed, the abnormal volumes calculated during the on-season are greater than the abnormal volumes computed during the off season. Likewise, we observed similar results as for the volatility. Secondly, this study demonstrates that the games’ results have a positive or a negative impact on the shares’ clubs returns depending on the game outcome. Indeed, the abnormal returns’ results are negative for losses and positive for wins. Moreover, we demonstrate that the stock market absorbs negative events (e.g. defeats) faster than the positive events (e.g. victories). Thirdly, we found that the losses that occur at the end of the season have more impact in terms of magnitude on the abnormal returns. On the contrary, the investors do not seem to react differently regarding the wins. Then, we were unable to find relevant findings regarding the unexpected results’ impact on the clubs’ share price. Surprisingly, we found that there is a surprise effect concerning victories whereas there is no surprise effect regarding the defeats.               Most of the findings of the study prove that public information concerning game results does influence investors’ behavior and thus have a significant impact on the share price of the famous European clubs.

Trois essais sur l’epargne salariale comme dispositif d’association des salaries a la croissance et au developpement de l’entreprise / Three essays on company based savings plans and shared capitalism

Bekrar, Yacine 15 March 2017 (has links)
Ce travail doctoral s’interroge sur les déterminants des comportements d’épargne salariale. Le chapitre 1 présente un état des lieux de l’épargne salariale. Nous détaillons ensuite les principales règles de fonctionnement de l’épargne salariale. Nous présentons enfin les principaux déterminants des comportements d’épargne salariale identifiés par la littérature. Le chapitre 2 examine les déterminants socio-économiques de l’efficience des portefeuilles d’épargne salariale. Il propose également une analyse des déterminants des erreurs d’investissement des salariés mesurées par un indice. Nous dissocions les investissements faits dans le cadre des augmentations de capital réservées aux salariés et ceux faits au titre des autres plans d’épargne entreprise. Nous nous intéressons d’une part à la décision binaire d’investir ou pas, et à l’efficience du portefeuille d’autre part. Notre échantillon porte sur 30 000 salariés d’un groupe bancaire français et contient des informations sur les caractéristiques individuelles des salariés et le détail des montants investis dans les plans et leurs caractéristiques de rentabilité et de risque. Les caractéristiques des salariés affectent significativement l’efficience des portefeuilles. Nous mettons en évidence une forte concentration en actions de l’entreprise. Nous montrons également que l’investissement des salariés est sous optimal compte tenu de l’écart existant entre le ratio de Sharpe optimal que nous avons calculés et le ratio de Sharpe des salariés. Nous régressons enfin cette différence sur les caractéristiques des salariés. Le chapitre 3 analyse empiriquement les déterminants de l’investissement en actions de l’entreprise. L’actionnariat salarié diminuerait les comportements de retrait des salariés tels que l’absentéisme et la rotation du personnel. Or, la causalité inverse que nous postulerons n’avait jamais été analysée : l’effet de l’absentéisme et de la rotation du personnel sur l’investissement en actions de l’entreprise par ses salariés. Nous montrons que l’absentéisme et la rotation du personnel affectent significativement la participation. Nous validons nos hypothèses de recherche à l’aide de diverses méthodes de régression. Nous analysons un panel d’environ 15 000 salariés de près de 900 filiales d’un groupe français coté appartenant au secteur de la construction, des travaux publics et des concessions sur une période de 5 ans. La participation au plan d’actionnariat salarié dépend du niveau d’absentéisme et de rotation du personnel au sein de l’entreprise. L’absentéisme et la rotation du personnel influencent l’investissement en actions de l’entreprise différemment selon la catégorie socioprofessionnelle du salarié et les motifs d’absences et de sorties Le chapitre 4 administre un questionnaire à des épargnants individuels afin d’évaluer leur connaissance financière. Nous nous sommes inspirés des enquêtes de Lusardi et de la Banque Centrale Européenne afin de réaliser un questionnaire adapté au cas français. Nous constatons l’influence de l’éducation financière sur les décisions d’investir. Le questionnaire a été diffusé auprès des salariés d’un établissement bancaire d’une part et de leurs clients d’autre part. Bien que nos résultats confirment dans l’ensemble la littérature sur la connaissance financière, nous identifions plusieurs nouveaux résultats. / This dissertation questions the determinants of employee savings behavior. Chapter 1 presents an overview of employee savings schemes. We then detail the main rules of employee savings schemes. Finally, we present the main determinants of the behavior of employee savings schemes identified by the literature. Chapter 2 examines the socio-economic determinants of employee savings’ portfolio efficiency. It also proposes an analysis of the determinants of investment errors of employees measured by an index. We dissociate investments made in the context of Employee stock purchase plan and those made through other employee savings plans. We are interested in the binary decision to invest or not on the one hand and in the portfolio efficiency on the other hand. Our sample covers 30,000 employees of a French bank, contains information on the individual characteristics of employees and details of the amounts invested in the plans, their risk and risk characteristics. The characteristics of the employees significantly affect the efficiency of the portfolios. We highlight a strong concentration of company stocks. We also show that the investment of employees is not optimal given the gap between the optimal Sharpe ratio and the actual Sharpe ratio. We finally regress this difference on the characteristics of the employees. Chapter 3 empirically analyzes the determinants of investment in company shares. Employee stock ownership would reduce the withdrawal behavior of employees, such as absenteeism and turnover. However, the reverse causality we assume had never been analyzed: the effect of absenteeism and the staff turnover on the investment in employer’s stocks. We show that absenteeism and staff turnover significantly affect participation. We validate our hypotheses using a variety of regression methods. We analyze a panel of approximately 15,000 employees of nearly 900 subsidiaries over a period of 5 years of a French listed company belonging to the construction, public works and concessions sector. Participation in employee stock ownership plan depends on the level of absenteeism and turnover of employees within the company. Absenteeism and staff turnover influence the investment in company shares differently depending on the employee's occupations category and the reasons for absences and departures. Chapter 4 analyze the results of a survey we sent to individual savers to assess their financial literacy. We translated the surveys of Lusardi and the European Central Bank to produce a questionnaire adapted to the French case. We see the influence of financial education on investment decisions. The questionnaire was distributed to the employees of a bank on the one hand and their customers on the other. Although our results generally confirm the literature on financial literacy, we identify several new findings.
