ABSTRACT After six years joining the World Trade Organization (WTO), Vietnam has enjoyed a lot of merits from its economic global integration; however it also faced with numerable challenges. In line with the broader achievement, Vietnam’s exchange rate regime has evolved from a system of multiple exchange rates to a single announced fixed rate, then to the current system of a narrow adjustable band around the official rate. The relationship between stock price and VND/USD exchange rate has always been an important issue for both investors and policy makers. This study presents an EGarch-M (1, 1) model with break to analyze the impact of exchange rate on stock return in Vietnam. Over the period from 2002 to 2011, the empirical results reveal the negative relationships between stock returns and VND/USD exchange rate, proving that VND/USD exchange rate works as the negative indicator of stock return in Vietnam , and the determinant of this phenomenon is the leverage shock between ''good news'' and ''bad news''.
