Are there any other companies applying artificial intelligence technologies to the stock market?
There are many people around the world attempting to apply artificial intelligence techniques (neural networks, fuzzy logic, support vector machines, genetic algorithms, etc..) to the financial markets. There have been many publicized stories of failures. Most of these failures were probably due to the misapplication of AI techniques on data that did not have a true cause-and-effect relationship with the financial markets. However, there are undoubtedly many success stories that have not been publicized.
