اعلامیه های سود و نقل قول ها از شرکت های متعلق به بانک های آمریکایی در مورد پیشنهاد خرید

This paper investigates the relationship between earnings announcements and quoted bid-ask spreads of US Bank Holding Companies (BHCs). Using a large sample of daily BHC market data, I hypothesize and find evidence of a positive relation between earnings announcements and the quoted bid-ask spread. I argue that this result is due to earnings releases helping to increase information asymmetries between informed traders and market makers.
