AI has long been applied to the problem of predicting financial markets. While AI researchers see financial forecasting as a fascinating challenge, predicting markets has powerful implications for financial economics—in particular the study of market efficiency. Recently economists have turned to AI for tools, using genetic algorithms to build trading strategies, and exploring the returns those strategies generate of evidence of market inefficiency. The primary aim of this thesis is to take this basic approach, and put the artificial intelligence techniques used on a firm footing, in two ways: first, by adapting AI techniques to the stunning amount of noise in financial data; second, by introducing a new source of data untapped by traditional forecasting methods: news. I start with practitioner-developed technical analysis constructs, systematically examining their ability to generate trading rules profitable on a large universe of stocks. Then, I use these technical analysis constructs as the underlying representation for a simple trading rule leaner, with close attention paid to limiting search and representation to fight over-fitting. In addition, I explore the use of ensemble methods to improve performance. Finally, I introduce the use of textual data from internet message boards and news stories, studying their use both in isolation as well as augmenting numerical trading strategies.
