The delay of stock price adjustment to information: A country-level analysis

This study measures the speed with which the aggregate stock market in 49 countries responds to global market-wide public information. Our empirical results show that there are wide variations in the aggregate price delay values over time and across countries. Subsequent panel analysis confirms previous firm-level evidence that market size, trading volume, short sales restrictions and the degree of investability are significant determinants of price delay even at the country level.
