Resumo: | This study analyses the effects of diversification in risk and return among the major global mining players. To evaluate the diversification, firstly, we created a ranking that relates risk, degree of diversification and return of the companies. It was mandatory to create a data base with a series of revenues and proxies of cash generation by business, which is not fully provided by Bloomberg, Economática or other public data bases. We estimated the effects of diversification by using the CAPM to calculate the companies’ beta and basic statistics of the historical return series to find the Sharpe Index. We looked through the financial statements to understand more profoundly their businesses for a sample equivalent to 50% of the market capitalization of the top 100 mining companies of the world for the period from 2002 to 2014. Finally, we approached, as a study case, essential issues in the diversification as efficiency and discipline in capital allocation. Our study confirmed the presence of a negative correlation between risk and diversification degree. It also showed evidences which suggest that focused companies have better discipline in capital allocation, and hence, generate more value to their shareholders. |

Para avaliar a diversificação, primeiramente, foi criado um ranking que relaciona risco, grau de diversificação e retorno das empresas. Foi necessário montar um banco de dados com séries de receita e de proxies de geração de caixa por negócios, o qual não se encontra prontamente disponível na Bloomberg, Economática ou em outras bases de dados públicas. Estimamos os efeitos da diversificação fazendo o uso do CAPM para calcular o beta das empresas e das estatísticas básicas das séries históricas de retornos para encontrar o Índice de Sharpe. Examinamos os demonstrativos financeiros das empresas para entender com maior profundidade seus negócios para uma amostra equivalente a 50% do valor de mercado das top 100 empresas de mineração do mundo para o período entre 2002 e 2014. Por fim, abordamos, sob a forma de estudo de caso, questões relevantes na diversificação como a eficiência e a disciplina na alocação de capital. Nosso estudo confirmou que existe uma correlação negativa entre o risco e o grau de diversificação e que há sinais que sugerem que as companhias mais focadas possuem maior disciplina na alocação do capital, e, com isso geram mais valor para seus acionistas.porRanking de diversificaçãoÍndice de Treynor e SharpeDisciplina na alocação de capitalDiversification rankingTreynor and Sharpe

This study analyses the effects of diversification in risk and return among the major global mining players. To evaluate the diversification, firstly, we created a ranking that relates risk, degree of diversification and return of the companies. It was mandatory to create a data base with a series of revenues and proxies of cash generation by business, which is not fully provided by Bloomberg, Economática or other public data bases. We estimated the effects of diversification by using the CAPM to calculate the companies’ beta and basic statistics of the historical return series to find the Sharpe Index. We looked through the financial statements to understand more profoundly their businesses for a sample equivalent to 50% of the market capitalization of the top 100 mining companies of the world for the period from 2002 to 2014. Finally, we approached, as a study case, essential issues in the diversification as efficiency and discipline in capital allocation. Our study confirmed the presence of a negative correlation between risk and diversification degree. It also showed evidences which suggest that focused companies have better discipline in capital allocation, and hence, generate more value to their shareholders. |
