Da casta ao terroir

Pela importância atual – e crescente – que o vinho tem na economia portuguesa, pela margem existente para a apresentação de temas de reflexão que acrescentem valor ao posicionamento do setor, pela experiência pessoal e paixão pela área, decidi elaborar a minha dissertação numa temática enquadrável no setor do vinho, em particular no vinho Alvarinho proveniente do terroir que representa a Denominação de Origem Vinho Verde Sub-região de Monção e Melgaço. A estrutura deste estudo assenta em duas dimensões: a primeira, numa perspetiva local, assente na recente decisão de alargar a Denominação Origem Vinho Verde Alvarinho a todas as sub-regiões que integram a Região dos Vinhos Verdes, com efeitos em 2021. Pelo que se procurará mostrar a importância da relação desta casta com o seu terroir de origem e, perante esta interligação, qual o fator mais importante a utilizar na comunicação do vinho. A segunda prende-se com a dimensão internacional que se pretende para o Alvarinho no mercado dos grandes vinhos brancos mundiais, onde encontramos castas brancas de renome como a Chardonnay e a Riesling, face a esta exposição e à crescente aposta na casta a nível mundial, como agir perante a potencial ameaça que representa a entrada dos países do “Novo Mundo”. Posto isto, é neste contexto que se coloca a questão que está na génese desta dissertação: de que forma o terroir contribui como fator de diferenciação e de vantagem competitiva do Alvarinho produzido na Denominação de Origem Vinho Verde Sub-região Monção e Melgaço no mercado dos grandes vinhos brancos mundiais? Cuja resposta poderá em grande parte estar, no meu entendimento, na análise de um caso de sucesso, que nesta dissertação é representada pelo trabalho realizado em torno do Rieseling produzido no Vale de Mosel e que contribuiu para que este tivesse conquistado a sua reputação.

A comprehensive analysis based on a set of economic and financial ratios was studied as an instrument which provides information on enterprise performance and its efficiency. It was selected a sample with 15 enterprises: 7 Portuguese and 8 Ukrainian ones, belonging to several industries. Financial and non-financial data was collected for 6 years, during the period of 2009 to 2014. Research questions that guided this work were: Are the enterprises efficient/profitable? What factors influence enterprises’ efficiency/performance? Is there any difference between Ukrainian and Portuguese enterprises’ efficiency/performance, which factors have more influence? Which industrial sector is represented by more efficient/profitable enterprises? The main results showed that in average enterprises were efficient; comparing by states Ukrainian enterprises are more efficient; industries have similar level of efficiency. Among factors that influence ATR positively are fixed and current assets turnover ratios, ROA; negatively influencing are EBITDA margin and liquidity ratio. There is no significant difference between models by country. Concerning profitability, enterprises have low performance level but in comparison of countries Ukrainian enterprises have better profitability in average. Regarding the industry sector, paper industry is the most profitable. Among factors influencing ROA are profit margin, fixed asset turnover ratio, EBITDA margin, Debt to equity ratio and the country. In case of profitability both countries have different models. For Ukrainian enterprises is suggested to pay attention on factors of Short-term debt to total debt, ROA, Interest coverage ratio in order to be more efficient; Profit margin and EBITDA margin to make their performance better. For Portuguese enterprises for improving efficiency the observation and improvement of fixed assets turnover ratio, current assets turnover ratio, Short-term financial debt to total debt, Leverage Ratio, EBITDA margin is suggested; for improving higher profitability track fixed assets turnover ratio, current assets turnover ratio, Debt to equity ratio, Profit margin and Interest coverage ratio is suggested.

Ratios and indicators that determine return on equity

This study aims to investigate factors that may affect return on equity (ROE). The ROE is a gauge of profit generating efficiency and a strong measure of how well the management of a firm creates value for its shareholders. Firms with higher ROE typically have competitive advantages over their competitors which translates into superior returns for investors. Therefore, seems imperative to study the drivers of ROE, particularly ratios and indicators that may have considerable impact. The analysis is done on a sample of 90 largest non-financial companies which are components of NASDAQ-100 index and also on industry sector samples. The ordinary least squares method is used to find the most impactful drivers of ROE. The extended DuPont model’s components are considered as the primary factors affecting ROE. In addition, other ratios and indicators such as price to earnings, price to book and current are also incorporated. Consequently, the study uses eight ratios that are believed to have impact on ROE. According to our findings, the most relevant ratios that determine ROE are tax burden, interest burden, operating margin, asset turnover and financial leverage (extended DuPont components) regardless of industry sectors.

Testemunhos da ocupação pré-histórica da Serra da Estrela

Em 1997, um de nós (A.G.) detectou, em um sector da margem direita da pequena albufeira criada na ribeira da Fervença pela barragem de Vale Ressim, na encosta setentrional da Serra da Estrela, cerca de 1,2 km a NNE das Penhas Douradas, um grande machado semienterrado, denunciado pela coloração escura da rocha constituinte, que contrastava com a coloração esbranquiçada dos granitos correspondentes aos afloramentos observados na zona.
