Kylie Cooper/ReutersAn artificial intelligence bot trained to pick stocks outperformed human investors by 600%, according to a new study. Researchers fed the AI market data from 1980 to 1990, and then simulated the next 30 years, giving the AI publicly available information from the time, and comparing its performance to real investors. The AI tended to use relatively simple variables, such as firm size and trading volume, but then it applied complex algorithms to squeeze as much predictive value as it could. The results were so striking that the team sat on them for a year “trying to find where we’d done something wrong.” An AI would likely not outperform real investors today, however, as they also have access to more sophisticated tools, including AI. |
