This paper simultaneously investigates the responses of stock prices of the related banks and the client firms when one of them is in distress. Two effects are examined. The distressed bank effect claims that the stock price of client firms are coupled to that of their related distress banks. The authors also propose the fund diversification hypothesis to suggest that related firms to the distressed banks are less hurt if the firms have various funds resources than the firms which do not. Namely, a well funded diversified firm should not be affected by the announcement of bad news of its related distressed banks. The distressed firm effect claims that the related banks are negatively affected when their client firms are in distress. The authors propose the leverage hypothesis, which argues that the related banks are more severely hurt when these banks lend more to their distressed firms than those lend less. Using the detail information of individual transaction loan data, they find the asymmetric responses between banks and their client firms. The results reject the distressed bank effect. The related banks apparently suffer from the bad news of their client firms, and the response of three largest related banks reacts even stronger than the case of using all related banks. The bank with higher exposures to the distressed firm experiences significantly higher valuation loss.
