Automated prediction of stock markets returns, based on wide spectrum of financial statements
Abstract
Historical stock markets data receive attention by researchers since the early days of modern econometrics. Many believe that historical data contains important models, which can be used for tracking of future movements in stock prices. But in many cases, this information offer only limited (and very often biased) overview of some of the indicators for public companies and offer very little context for the long term internal processes. For this reason, models based solely on historical returns in general performs poorly and can be useful only for short term modeling of returns. After entering in the digital era, significant part of the management processes of companies became computer-driven. This made access to internal accounting data much easier and offered unique possibility to include various indicators from companies balance sheets for improvement of existing forecasting models. In this paper will be reviewed innovative ML-based system for generation of predicting models, proposed in recent paper by Bogdanova et. al. (2021), based on combined input from historic price data and set of variables from accounting reports.
