O objetivo principal deste estudo é determinar se o modelo de qualidade dos lucros criado pela Thomson Reuters Eikon está de alguma forma correlacionado com um dos modelos académicos mais usados na literatura de EQ. Além disso, este estudo procura aprofundar o conhecimento sobre os modelos quantitativos elaborados por bases de dados eletrónicas, mais especificamente o modelo de EQ da Eikon. Para a primeira parte da análise foram realizados testes de correlação, de Spearman e Pearson, realizados entre os dois modelos. De seguida, foi construída uma regressão usando o trabalho de Bens et al. (2019), adaptada ao objetivo deste estudo. Os resultados obtidos na análise de correlação sugerem que o modelo Eikon está positivamente correlacionado com o modelo académico, embora seja um valor fraco para ambos os testes. Porém, em nenhuma das análises foi possível identificar um padrão ou motivo evidente para os resultados da correlação positiva por país, setor e ano. Além disso, determinou-se que a relação entre os dois modelos é melhor explicada quando se considera o tamanho da empresa, o nível de endividamento, o número de analistas que acompanham a empresa e o índice de rendibilidade dos ativos.
The main aim of this study is to determine if the earnings quality model provided in Thomson Reuters Eikon is correlated with one of the most used academic measures for EQ. Moreover, this study tries to deepen the knowledge on the quantitative models created by electronic databases, namely the Eikon EQ score. For the first part of the analysis Spearman and Pearson correlation tests, were performed between the two models. After that, a regression was constructed using the work by Bens et al. (2019), adapted to the purpose of this study. The results obtained through the correlation analysis suggest that Eikon model is positively correlated with the academic model, albeit it being a small value for both tests. However, it was not possible to identify a pattern or evident reason for the positive correlation results by country, industry and year present in the sample. Additionally, it was determined that the relation between the both models is better explained when taking company size, level of debt, number of analysts following the firm and return on assets ratio.
