Artificial intelligence can offer better returns than traditional investing approaches, but many artificial intelligence techniques are not easy to explain, and many are not transparent. While there have been efforts to make such black-box methods explainable, the results can be difficult to interpret as well as misleading, presenting a potentially serious problem for investment managers. In contrast, investment choices determined using factor-based models with linear regression tend to be interpretable, yet the performance of factor-based models has been poor, falling short of expectations. An SAI investing approach offers the potential to significantly outperform traditional factor-based investing while also providing a transparent, easily understandable explanation of the decision-making process.
