Recent Research:
One of Prof. Fahlenbrach’s latest co-authored studies investigates investors’ and firms’ reactions to the unexpected currency shock that occurred in Switzerland a year ago. Studying publicly listed companies, the researchers find large negative announcement returns for firms with significant currency exposure. Such firms experienced, on average a 9.7 percent drop in profitability compared to other Swiss firms, which took a 4.9 percent hit. The appreciation of the Swiss franc also had real effects. The most exposed firms experienced a large drop in sales and profitability, significantly reduced their capital expenditures, and shifted production abroad.
