This
paper investigated the volatility spillover effects between Islamic stock
markets and Korean stock market using the AR-DCC-GARCH models. First, we found
bi-directional volatility transmissions between the Islamic and Korean
financial markets. Second, we compared the correlation of KOSPI-DJIM portfolio
and that of KOSPI-SHX portfolio. It shows the former has stronger linkage than
the latter. In the portfolio perspective, the S&P 500 Sharia stock Index (SHX)
acts as a better hedge asset than DJIM against the risk of stock market. Lastly,
the hedge ratio between two Islamic stock market and Korean stock market pairs
is generally low, indicating that the Korean stock risk can be effectively
hedged by taking a short position in the Islamic stock markets. In comparison
with two pairs, the pair of KOSPI-SHX relatively shows a cheaper hedging cost
than that of KOSP-DJIM pair. This evidence indicates that S&P 500 Sharia
index serve more effective hedging role against the risk of Korean stock
market.

KORE STOK PAZARINDA İSLAM EŞİTLİ PORTFÖY YÖNETİMİ

Öz

Bu makalede, AR-DCC-GARCH modelleri kullanılarak İslami borsalar ile Kore borsaları arasındaki oynaklıkların yayılma etkileri araştırılmıştır. İlk olarak, İslami ve Kore finans piyasaları arasında iki yönlü dalgalanmalar bulundu. İkincisi, KOSPI-DJIM portföyünün ve KOSPI-SHX portföyünün korelasyonunu karşılaştırdık. İlkinin ikincisinden daha güçlü bir bağlantı olduğunu gösterir. Portföy perspektifinde S & P 500 Sharia hisse senetleri endeksi (SHX), hisse senedi piyasası riskine karşı DJIM'den daha iyi bir hedging varlıkları olarak hareket etmektedir. Son olarak, iki İslami hisse senedi piyasası ile Koreli borsa çiftleri arasındaki risk oranı genel olarak düşüktür. Bu durum, Koreli hisse senedi piyasalarının İslami borsalarda kısa bir pozisyon alarak etkin bir şekilde korunabileceğini göstermektedir. İki çiftle karşılaştırıldığında, KOSPI-SHX çifti nispeten KOSP-DJIM çiftininkinden daha ucuz bir hedging maliyeti gösterir. Bu kanıt, S & P 500 Sharia endeksinin Koreli borsa riskine karşı daha etkin bir riskten korunma rolüne hizmet ettiğini göstermektedir.
