Which industries are most severely affected by the COVID-19 pandemic? A data-mining approach to identify industry-specific risks in real-time

While the coronavirus spreads around the world, governments are attempting to reduce contagion rates at the expense of negative economic effects. Market expectations have plummeted, foreshadowing the risk of a global economic crisis and mass unemployment. Governments provide huge financial aid programmes to mitigate the expected economic shocks. To achieve higher effectiveness with cyclical and fiscal policy measures, it is key to identify the industries that are most in need of support. In this study, we introduce a data-mining approach to measure the industry-specific risks related to COVID-19. We examine company risk reports filed to the U.S. Securities and Exchange Commission (SEC). This data set allows for a real-time analysis of risks, revealing that the companies' awareness towards corona-related business risks is ahead of the overall stock market developments by weeks. The risk reports differ substantially between industries, both in magnitude and in nature. Based on natural language processing techniques, we can identify-specific corona-related risk topics and their relevance for different industries. Our approach allows to cluster the industries into distinct risk groups. The findings of this study are summarised and updated in an online dashboard that tracks the industry-specific risks related to the crisis, as it spreads through the economy. The tracking tool can provide crucial information for policy-makers to effectively target financial support and to mitigate the economic shocks of the current crisis.
