[en] PORTFOLIO SELECTION USING NON PARAMETRIC TECHNIQUES / [pt] SELEÇÃO DE CARTEIRAS UTILIZANDO TÉCNICAS NÃO PARAMÉTRICAS

ANDRE MACHADO CALDEIRA 01 September 2005 (has links)
[pt] Nos anos 50, Henrry Markowitz criou um modelo que maximiza a razão entre a média e o desvio padrão [Markowitz, 1952 & 1959]. Esse modelo é muito utilizado até os dias de hoje. Porém ele supõe que os retornos dos ativos do portifólio sejam normalmente distribuídos, e isso não é tão comum, logo seu uso é limitado. Esse trabalho propõe um modelo mais robusto em termos de risco, que possa ser utilizado sem restrições de distribuições, não necessitando do conhecimento a priori das distribuições e que seja uma aproximação do modelo de Markowitz, caso os retornos dos ativos sejam normalmente distribuídos. Para possibilitar isso, o índice maximizado pelo modelo de Markowitz é escrito como uma função da média e da entropia. A seleção do portifólio é dada pelo portifólio que obtiver o maior índice proposto dentro da amostra selecionada. / [en] In the 50 s, Henrry Markowitz created a model that maximizes the mean to standard deviation ratio [Markowitz, 1952]. This model is largely use in the financial market. However, it assumes that portfolio s equities returns are normally distributed, and this not always happens, therefore limiting its use. This work proposes a more robust model in risk measure that can be used without any distribution constraint, however it reduces to Markowitz model if the assets returns are normal distributed. To make it possible, the index maximized by Markowitz will be written as a function of the mean and the entropy. The portfolio selection is that one witch has the largest proposed index in the selected sample.

Análise de desempenho das maiores administradoras de fundos de investimentos de renda fixa no Brasil

Braga, Alexandre Xavier Vieira 21 December 2005 (has links)
Made available in DSpace on 2015-03-05T19:11:30Z (GMT). No. of bitstreams: 0 Previous issue date: 21 / Nenhuma / A indústria de fundos de investimento no Brasil está concentrada no segmento de renda fixa. Dos cerca de R$ 220 bilhões depositados em fundos, hoje, R$ 200 bilhões aproximadamente estão nesse segmento e R$ 20 bilhões em carteiras de renda variável. Observou-se que no primeiro semestre de 2002, os fundos de investimento em geral tiveram alguns problemas que diminuíram bastante os seus retornos. A mudança da métrica de avaliação dos fundos, da chamada Curva de Juros para a Marcação a Mercado, provocou profundas transformações em termos de mensuração de valor dos fundos de renda fixa. Neste contexto, verificou-se a performance das 17 maiores administradoras de fundos no período 1997-2003 com dados diários. O método empregado foi a Análise de Dados em Painel. A hipótese de que as administradoras de fundos nacionais privadas obtêm igual relação risco-retorno em suas carteiras do que as administradoras de fundos nacionais estatais e as administradoras de fundos estrangeiras não foi comprovada. As administradoras es / The industry of investment fund in Brazil is concentrated in the segment of fixed income. About R$ 220 billion are deposited in funds nowadays, from which R$ 200 billion approximately are in the fixed income segment and R$ 20 billion in variable income portfolios. In the first semester of 2002 it was observed that investment funds in general had substantially reduced their returns. In the wake of the change of the evaluation metrics of funds from yield curves to mark-to-market, caused profound transformation in the value of fixed income funds. In this context, the performance of the 17 biggest asset management firms in the period 1997-2000 in a daily basis has been assessed. The hypothesis that private Brazilian asset management firms have a similar risk-return performance in their portfolios as state and foreign firms has been rejected. Foreign asset management firms had a superior performance with respect to Brazilian private firms, while private firms sustained a superior performance vis-à-vis state firms

A Comparative Study on Green Mutual Equity Fund’s Financial Performance : International vs Domestic Fund Composition

Aiyadurai, Janusa, Brenckert, Mathias January 2020 (has links)
In this thesis the relationship between regional composition and risk-adjusted performance is evaluated concerning Swedish issued green mutual equity funds. By using three different indices; Sharpe, Jensen and Treynor, a relationship has been able to establish. The study finds no strong relationship between geographic composition and performance concerning any of the indices and thus the impact of diversifying one's portfolio has little impact. By using the Modern Portfolio Theory, Stewardship Theory, Home Bias Theory and Behavioral Finance Theory a theoretical discussion has been established in order to further examine and analyze the fundamental dynamics of this relationship. Lastly, model risk and other variables impact on performance has been investigated. Our study finds a potential model risk since our three indices results disparate. Further, ESG related factors and Morningstar ratings seem to impact performance greater than regional composition.
