Firms do not function in isolation in the marketplace. They are linked to each other through various channels, such as their supply chain networks, board of directors, similar fundamentals and industry sectors, as well as market conditions. These channels allow continuous information exchanges among firms in the financial markets.

This interconnectedness among firms through contemporaneous links forms the firms’ network. Previous studies suggest that the structure, properties, and dynamism of a network provide important insights into how information flows and shocks propagate across firms and thereby affect their stock prices.
