Abstract

The management of financial risks, which is a branch of financial theory, is defined as a process that begins with risk factors identification, continues with measurement of risk and concludes with the coverage of that risk. This work focuses on the second phase of management process, namely the measurement of risk. This can be defined as an uncertainty which has an impact on the wealth and can be measured by different ways. Indeed, it is possible to distinguish, for each risk category, a set of evaluation methods (for example: the semi-variance for equity risk, the convexity degrees for risk associated with bonds and Value-at-Risk (VaR) for the global risk of portfolio). The use of measurement risk in a portfolio of securities is necessary as far as it facilitates the understanding of theoretical concepts and the use of mathematical formulas.
