Trading risk is a research concept within financial economics and risk management that systematically investigates the potential for adverse financial outcomes resulting from fluctuations in market prices, changes in liquidity, counterparty creditworthiness, or operational issues inherent in the buying and selling of financial instruments. This field encompasses the theoretical frameworks and quantitative methodologies used to identify, measure, monitor, and mitigate these exposures, aiming to enhance financial stability, inform regulatory policy, and optimize investment strategies.
