Abstract AR
تفحص هذه الدراسة العلاقة بين عوائد الأسهم و التذبذب فيها، بالإضافة الى قياس" استمرار التذبذب" في الفترة الواقعة بين 1992 و 2002 لأسواق ست دول صاعدة.
تم استخدام أسلوب Exponential GARCH و GARCH in mean كما تم فحص هذه النماذج بعد تعديلها "للتغيير المفاجئ" خلال تلك الفترة.
دلت النتائج الإحصائية على وجود العلاقة النظرية بين العائد و المخاطرة للأسواق قيد الدراسة.
و بعد التعديل لاحتمالية أي تغيير مفاجئ في التباين خلال فترة الدراسة باستخدام طريقة Iterative Cumulative Sums of Squares (ICSS) بقيت العلاقة الإيجابية المستمرة بين العائد و المخاطرة موجودة.
Abstract EN
This paper examines the relationship between stock market returns and volatility and extends to measure the degree of persistence in volatility over the period from 1990 through 2002 for selected emerging markets.
Using GARCH in mean, Exponential GARCH and by incorporating sudden change in volatility effect in the GARCH/E-GARCH models, the relationship between stock returns and variance was tested.
Empirical evidence suggests that contemporaneous returns and volatilities for the majority of the markets are significantly and positively correlated.
The volatility proves to be persistent across countries.
To account for sudden change in variance, the Iterative Cumulative Sums of Squares (ICSS) are used to identify the points of shifts in volatility.
ICSS results are significant, come in accordance with the identified points and confirm that the events and news cause shifts in volatility of stock returns.
JEL Specification: G15, G14.
KEYWORDS: Volatility, Sudden Change.
