Resumo: | The objective of this thesis is to study whether introducing fundamental measures of volatility in a model already accounting for market-based volatility can contribute to better explain the variation in credit default swap spreads. The accounting-based measures of volatility considered are (i) volatility of the return on net operating assets and (ii) volatility in the dispersion in analysts’ forecasts of earnings per share. When only the market volatilities are modelled together, it produces a r-square of around 67.5%. When considering the market-based volatilities and the volatility of the return on net operating assets in the same model, the explanatory power increases to around 73.5%. In the instance where all the market-based volatilities, the volatility of the return on net operating assets, and volatility in the dispersion in analysts’ earnings forecasts are considered, there is a slight decrease in r-square to around 73.0%. The results suggest that accounting measures help increase the explanation of the variation in credit default swap spreads, however adding the volatility in the dispersion in analysts’ forecasts of earnings, as a second accounting-based measure, does not add any explanatory power to the model. In further robustness tests, all volatilities measures are untouched except the return on net operating assets, which is replaced firstly by return on assets and secondly by return on equity. The robustness test results fall in line with the original findings. This corroborates that the analysis of credit default swaps can be increased by introducing accounting-based information into the models. |

As medidas de volatilidade contabilísticas consideradas são (i) volatilidade da rendibilidade dos ativos líquidos de exploração e (ii) volatilidade da dispersão das previsões dos analistas dos resultados por ação. No modelo em que apenas as volatilidades de mercado são consideradas é obtido um r-quadrado de cerca de 67.5%. Ao modelar as volatilidades de mercado em conjunto com a volatilidade da rendibilidade dos ativos líquidos de exploração, verifica-se um aumento do poder explicativo para cerca de 73.5%. Quando todas as volatilidades de mercado, a volatilidade da rendibilidade dos ativos líquidos de exploração e a volatilidade da dispersão das previsões de resultados são consideradas, verifica-se uma ligeira diminuição do r-quadrado para cerca de 73.0%. Os resultados sugerem que medidas contabilísticas ajudam a aumentar a explicação da variação dos spreads de credit default swaps; no entanto, a adição da volatilidade da dispersão das previsões de resultados, não acrescenta poder explicativo ao modelo. Em testes de robustez, todas as medidas de volatilidade mantêm inalteradas, exceto a rendibilidade dos ativos líquidos de exploração, que é substituída, primeiramente, pela rendibilidade dos ativos e, segundamente, pela rendibilidade dos capitais próprios. Os resultados dos testes de robustez vão de acordo com as conclusões iniciais. Isto corrobora que a análise dos credit default swaps pode ser melhorada através da introdução de informação contabilística.Silva, NunoVeritati - Repositório Institucional da Universidade Católica PortuguesaMartinho, Bruno Miguel Vaz2023-12-05T01:30:56Z2023-06-282023-062023-06-28T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.14/42580TID:203326547enginfo: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:RCAAP2023-12-12T01:35:04Zoai:repositorio.ucp.pt:10400.14/42580Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T20:31:00.907510Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
