The difficulty of predicting the movement of financial assets is the
subject of study by several authors. In order to obtain gains, it is necessary
to estimate the direction (rise or fall) and the magnitude of the return on
the asset in which it is intended to be bought or sold. The purpose of this
work is to develop a mathematical optimization model with binary variables
capable of predicting up and down movements of financial assets and using
a portfolio optimization model to evaluate the results obtained. The prediction
model will be based on the textit Support Vector Machine (SVM),
in which we will make modifications in the regularization of the traditional
model. For the portfolio management will be used robust optimization. The
robust optimization techniques are being increasingly applied in portfolio
management, since they are able to deal with the problems of the uncertainties
introduced in the estimation of the parameters. It is noteworthy that
the developed model is data-driven, i.e., the predictions are made using
nonlinear signals based on past historical price / return data without any
human intervention. As prices depend on many factors it is to be expected that a set of
parameters can only describe the dynamics of the prices of financial assets
for a small interval of days. In order to more accurately capture this change
in dynamics, the estimation of model parameters is done in a moving window
To test the accuracy of the models and the gains obtained, a case study
was made using 6 financial assets of the currencies, fixed income, variable
income and commodities classes. The data cover the period from 01/01/2004
until 05/30/2018 totaling a total of 3623 daily quotations. Considering the
transaction costs and out-of-sample results obtained in the analyzed period,
it can be seen that the investment portfolio developed in this work shows
higher results than the traditional indexes with limited risk.
