NVIDIA'NIN VOLATİLİTESİNİN GELİŞMEKTE OLAN PAZARLARA YAYILMASI: KISA VE UZUN VADELI ETKILER

Öz

Bu çalışma, günlük hisse senedi verilerini kullanarak Nvidia'nın (NVDA) Brezilya, Endonezya, Tayvan, Şili ve Hindistan dahil olmak üzere çeşitli gelişmekte olan piyasalara potansiyel volatilite yayılımlarını analiz etmektedir. GSADF testi ve Diebold ve Yılmaz'ın (2012) volatilite yayılma metodolojisi kullanılarak elde edilen sonuçlar, Nvidia'nın spekülatif balonunun bu gelişmekte olan piyasalar üzerinde minimum kısa vadeli etkilere sahip olduğunu göstermektedir. Ancak, uzun vadede, Nvidia bu piyasalara, özellikle Brezilya, Endonezya, Tayvan ve Şili'ye önemli ölçüde volatilite aktarmaktadır. Özellikle, Nvidia oynaklığının %17,03'ünü Brezilya'ya, %16,16'sını Endonezya'ya, %13,63'ünü Tayvan'a ve %12,2'sini Şili'ye aktarmaktadır. Bu sonuçlar, Nvidia'nın spekülatif balonunun patlamasının bu gelişmekte olan piyasaların finansal istikrarı üzerinde uzun vadede önemli bir etkisi olabileceğini göstermekte ve küresel teknoloji şirketleri ile gelişmekte olan piyasalar arasında artan karşılıklı bağımlılığın altını çizmektedir.

NVIDIA'S VOLATILITY SPILLOVERS TO EMERGING MARKETS: SHORT- AND LONG-TERM EFFECTS

Abstract

This study analyzes potential volatility spillovers from Nvidia (NVDA) to several emerging markets, including Brazil, Indonesia, Taiwan, Chile, and India, using daily stock data. The results, obtained using the GSADF test and Diebold and Yılmaz's (2012) volatility spillover methodology, show that Nvidia's speculative bubble has minimal short-term effects on these emerging markets. However, in the long run, Nvidia transmits significant volatility to these markets, especially to Brazil, Indonesia, Taiwan, and Chile. Specifically, Nvidia transmits 17.03% of its volatility to Brazil, 16.16% to Indonesia, 13.63% to Taiwan, and 12.2% to Chile. These results suggest that the bursting of Nvidia's speculative bubble could have a significant long-term impact on the financial stability of these emerging markets, highlighting the growing interdependence between global technology companies and emerging markets.
