Resumo: | Caixabank, the Spanish bank that belongs to the "La Caixa" financial group, has been BPI's shareholder for more than twenty years and since 2015 it has tried to take over the Portuguese bank. The ultimate takeover bid was in January 2017 and Caixabank became BPI's majority shareholder in February 2017. This thesis main objective is to study the impact this takeover had on BPI's security, focusing on measuring the unexpected performance of the stock. Thus, we applied the event study methodology, using the market model as estimation model and choosing an estimation and event window that better fitted the corresponding event. We computed the abnormal returns for the event window days and evaluated if these returns were statistically significant, presenting the main findings obtained. This thesis outcome reveals that the takeover had a negative impact on BPI's security price, which was statistically significant on the day of the takeover and the following day. Moreover, we observed the takeover had an unfavorable effect for the stock, which ended up being excluded from the PSI 20 index. |

A derradeira oferta pública de aquisição foi em janeiro de 2017 e o Caixabank tornou-se acionista maioritário em fevereiro de 2017. O principal objetivo desta tese é estudar o impacto que esta aquisição teve no título do BPI, mais precisamente, quantificar a performance inesperada da ação. Assim, aplicámos a metodologia de estudo de eventos, utilizando o Modelo de Mercado como modelo de estimação e tendo em conta a janela temporal de evento e de estimação que se adapta melhor ao respetivo evento. Calculámos os retornos anormais dos dias correspondentes à janela temporal do evento e avaliámos a significância estatística destes retornos, apresentando os principais resultados obtidos. O resultado desta tese evidencia que a aquisição teve um impacto negativo no preço da ação do BPI, sendo que este foi estatisticamente significativo no dia da aquisição e no dia a seguir. Para além disso, observámos que a aquisição teve um efeito desfavorável para a ação, que acabou por ser excluída do índice PSI 20.2019-09-12T13:35:16Z2018-11-15T00:00:00Z2018-11-152018-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/octet-streamhttp://hdl.handle.net/10071/18641TID:202104842engJesus, João Pereira Pedro deinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-09T17:32:59Zoai:repositorio.iscte-iul.pt:10071/18641Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:14:49.572139Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
