Abnormal returns, risk, and financial statement data: The case of the Iraqi invasion of Kuwait

This paper examines abnormal returns and changes in risk for transportation firms immediately around the Iraqi invasion of Kuwait. Further, it tests whether the variation in the abnormal returns can be explained cross-sectionally with standard financial and industry-descriptive variables. The results indicate that transportation firms suffered a −2.09% abnormal return and increases in unsystematic risk. The cross sectional regression explains 31% of the variation in the abnormal returns, with firm size, liquidity, leverage, percentage of sales to the Department of Defense, and dummy variables denoting firms producing recreational vehicles or owning oil-producing subsidiaries contributing significantly to the regression.
