Abstract

Purpose – The purpose of this study is to investigate the response of Turkish investors and the persistency of these reactions following the Volkswagen scandal. Design/methodology/approach – For this purpose, the stock price changes of Dogus Otomotiv Servis ve Ticaret AŞ (DOAS) which is Volkswagen AG's distributor in Turkey are examined. Firstly, daily abnormal returns of DOAS are obtained by using Capital Asset Pricing Model and then the daily abnormal returns are modeled by ARMA and EGARCH. Findings – This study show evidences of that Turkish investors can react systematically to the news about Volkswagen both in return and volatility. However, some evidence indicates that the impact of the reactions is weak and not persistent. Discussion – The fact that the response of Turkish investors came one day after the response of investors in US shows that this reaction may not be related to the EPA report rather may be related to the response of US investors, or that Turkish investors reaction is not simultaneous with US investors.

Özet

Amaç – Bu çalışmanın amacı, Volkwagen skandalının ortaya çıkmasının ardından Türk yatırımcıların verdiği tepkileri ve bu tepkilerin kalıcılığını araştırmaktır. Yöntem – Çalışmada, Volkswagen AG’nin Türkiye distribütörü olan Doğuş Otomotiv Servis ve Ticaret A.Ş.’ ye ait hisselerdeki (DOAS) getiri ve oynaklık değişiklikleri incelenmiştir. Öncelikle Sermaye Varlıkları Fiyatlama Modeli yardımıyla DOAS hisselerinin günlük anormal getirileri elde edilmiş, daha sonra günlük anormal getiriler için ortalama modeli olarak ARMA ve oynaklık modeli olarak EGARCH kullanılmıştır. Bulgular – Çalışmada, Volkswagen hakkında çıkan haberler karşısında Türk yatırımcıların sistematik tepkisinin, hem getirilerde hem de oynaklıklarda gözlemlenebildiği fakat bu tepkinin etkisinin zayıf ve oldukça kısa sürdürdüğüne ilişkin kanıtlar sunulmuştur. Tartışma – Türk yatırımcılar tarafından verilen tepkinin, ABD’deki yatırımcılar tarafından verilen tepkiden 1 gün sonra gelmesi bu tepkinin aslında EPA raporundan çok ABD yatırımcılarının hareketleri ile ilgili olduğunu ya da Türk yatırımcıların bu tür olaylara geç tepki verdiğini göstermektedir.
