The use of neural networks provides an interesting alternative to the statistical classifier. We can take a decision on the purchase or sale of a given asset, using a neural network to classify the process into three decisions: buy, sell or do nothing. \itemrv{~} \itemcc{} \itemut{portfolio payoff risk neural network} \itemli{doi:10.1007/978-3-540-77226-2\_98} \end
