| Abstract: | This paper investigates financial time‐series from the perspective of a practitioner in artificial intelligence methods and pattern recognition. It presents results from statistical experiments which suggest that financial markets operate with a measure of inefficiency and predictability. However, identifying the nature of any regularities and patterns presents a difficult challenge to the artificial intelligence community, in that established techniques make assumptions about the underlying process that mostly prove to be invalid for this class of data.
