Este trabalho visa reproduzir e sintetizar o que é entendido como estrutura de correlações no mercado financeiro. A análise da estrutura consistirá de 2 partes, uma dinâmica, acessando dependências temporais, e outra topológica e economica, acessando a importância das conexões entre ações. Na análise dinâmica são investigadas a correlação instantânea, quanto o comportamento ao longo das escalas de tempo , e a não instantânea, quanto ao decaimento temporal em relação ao máximo de correlação. A topologia é analisada obtendo-se um grafo a partir da matrix de correlação instantânea e analisando a conectividade dos vértices, partindo do mais conectado(chama-se raíz) analisa-se os diversos clusteres de ações obtidos, comparando com a classificação economica conhecida. A analise topológica é feita em várias escalas de correlação instantânea visando a comparação entre elas. Introduzo noções gerais de sistemas complexos no capítulo 1. No capítulo 2 dou uma breve descrição do mercado através das varíaveis mais importantes e seu comportamento, i.e. as escalas de preços e de tempo. O capítulo 3 descreve os métodos utilizados para análise da estrutura de correlação do mercado, é apresentado o estimador de Pearson para correlação linear bem como o método de Kruskal, utilizado para obter o grafo árvore que contém todas ações e minimizar a soma das arestas (ponderadas pela distância definida a partir da correlação). No capítulo 4 apresento os resultados referentes à análise da estrutura de correlações para o mercado Bovespa / In systems where many agents interact, allowing for measures that may be erratic, many times we can extract behavior patterns that denote a group of agents, this is the case of financial market and its emerging structure of correlations. This work aims to reproduce and synthesize what is perceived as a correlation structure in financial markets. Analysis of the structure will consist of 2 parts, one dynamic, accessing temporal dependencies, and other topological and economical by accessing the importance of connections between assets. In analysis of dynamics are investigated instantaneous correlation, it’s behavior across scales of time, and the not instantaneous, it’s decay from the maximum correlation. The topology is analyzed by a graph from the instantaneous correlation matrix and analyzing the connectivity of vertices, starting from the most connected (called root) analyzes the various clusters of shares obtained by comparing with known economic classification. The topological analysis is performed at several scales of correlation in order to instantly compare them. Introduce general notions of complex systems in Chapter 1. In Chapter 2 give a brief description of market through the most important variables and their behavior, ie the ranges of price and time. Chapter 3 describes the methods used for analysis the correlation structure of the market, the estimator is presented by Pearson’s linear correlation and the Kruskal method is used to obtain the graph tree containing all assets and to minimize the sum of edges (weighted by the distance defined from the correlation). In Chapter 4 I present the results of the analysis of correlation structure for the market Bovespa

Bibliography: pages 77-82. / Although the proposed alternative monetary regimes have received critical attention from White (1984), McCallum (1985), O' Driscoll ( 1987) and Hoover ( 1988), we are not aware of any systematic and coherent critical appraisal. The main motivation for this paper is that neither the originators nor the critics seem thus far to have provided satisfactory treatments of the 'operationality' of the above proposals. Considering that most of the proposed payments systems are forwarded as potential alternatives to existing fiat currency systems, this is a serious shortcoming. For each proposed payments system that this paper considers, the analytical method which is adopted for this objective is as follows: (I) The institutional arrangements defining the proposed payments system are specified. (II) This payments system is then embedded in an economy in which pricing decisions are made by agents in decentralised markets.

A research report submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Management in Finance and Investment, 2017 / Capital markets reforms in emerging, and particularly African markets are of a growing concern. Despite various institutional reforms that began in the early 1980s, the capital markets in emerging countries still exhibit signs of illiquidity, high volatility of returns, high concentration levels and inefficiency. Ambiguous results for such reforms have brought into question the affectivity of major capital markets reforms such as change of settlement cycles, particularly in countries where stock markets are sponsored with public funds. This thesis, therefore, intends to assess the effectiveness of capital markets reforms on development of stock markets by looking at the impact of changing settlement cycle on risk and liquidity at JSE. The objective is met through an assessment of a link between institutional structures and stock micro-structural variables, especially liquidity and risk in the literature review and an assessment of past studies on effects of stock market reforms and changes of settlement cycle on liquidity, risk and efficiency of stock markets. The study then tests the effects of settlement cycle on risk by assessing changes in abnormal returns and changes of variance of returns as a result of settlement cycle change at JSE. It also looks at the impact on liquidity by assessing the effects on the illiquidity measure first proposed by Amihund and Mendeison (2002). The study finds that change of settlement cycle at JSE had positive effects of reducing risk and increasing liquidity. The study also finds that there are no effects on trading activity and concludes that changing settlement cycle impacts largely on risk and to a smaller extend liquidity. / MT 2019
