This paper examines the interdependence between Taiwanese and international stock market indices. We choose NASDAQ Composite index, Dow Jones Industrial Average index, TSEC weighted index, NIKKEI 225 index, Hang Seng index, SSE Composite index as our research objects. In this paper, we use both weekly data and monthly data for our analyses. As the Financial Tsunami may change the interdependence between any two indices, raw data will be divided into Pre-Tsunami and Post-Tsunami period for further consideration.
