内容简介:

An AI analyst we build to digest corporate financial information, qualitative disclosure and news is able to beat the majority of human analysts in stock forecasts and generate excess returns compared to following human analysts alone. In the contest of “machine vs. human,” we find that the relative advantage of such an AI Analyst is stronger when the firm is complex, and when information is high-dimensional, transparent and voluminous. Human analysts remain competitive when critical information requires institutional knowledge (such as the nature of intangible assets). The edge of the AI analyst over human analysts declines over time, when analysts gain access to alternative data and to in-house AI resources. Combining AI’s computational power and the human art of understanding soft information produce the highest potential in generating accurate forecasts. Our paper suggests a future of “machine plus human” in high-skilled professions as an alternative to the replacement of humans by machines.
