Abstract

This Article suggests a link between insider trading regulation and macroeconomic risk. Current securities laws do not explicitly prohibit a company insider from trading in the stocks of her company’s suppliers, customers, competitors, and complementors (based on material, non-public information regarding her company). But such “network trades” can be highly profitable, and as a result, can encourage corporate risk-taking by company insiders. As insights from network theory reveal that such risk-taking incentives will be significantly greater among insiders in industries that have a larger impact on macroeconomic risk, the possibility of network trades increases macroeconomic risk.

Keywords: insider trading; macroeconomic risk; network theory; systematically important financial institutions; risk-taking; network trades; shadow trades; aggregate fluctuations
