Abstract:

Bu çalışmanın amacı, yapısal kırılmalar altında asimetrik bilginin hisse senedi getiri oynaklığı üzerindeki etkisini ARFIMA-FIGARCH ikili uzun hafıza ve Markov Switching Regresyon modelleriyle ortaya koymaktır. Bu doğrultuda, çalışmada BİST 100 Endeksi’nin 04.01.2010-31.12.2018 dönemine ilişkin günlük dolar cinsinden kapanış fiyatları, alım satım fiyat marjı ile toplam işlem hacmi verileri dikkate alınmıştır. Çalışmada getiri serisinin varyansındaki muhtemel kırılmalar Sanso vd. (2004)’in varyansta kırılma testiyle araştırılmış ancak herhangi bir yapısal kırılma tespit edilememiştir. Bu nedenle yapısal kırılmalar dikkate alınmaksızın hisse senedi getiri oynaklığı serisi için en uygun oynaklık modeli ARFIMA-FIGARCH modeliyle araştırılmış, en uygun modelin çarpık student t dağılımına göre ARFIMA(3ξ,4)- FIGARCH (1,d,1) modeli olduğu tespit edilmiştir. Çalışmada son olarak, asimetrik bilginin hisse senedi getiri oynaklığı üzerindeki etkisi Markov Switching Regresyon modeliyle araştırılmıştır. Sonuç olarak, alım satım fiyat marjının hisse senedi getiri oynaklığı üzerinde her iki rejimde de arttırıcı bir etkisinin olduğu tespit edilmiştir. Ayrıca tutar cinsinden toplam işlem hacminin Rejim 1’de hisse senedi getiri oynaklığını arttırıcı Rejim 2’de ise azaltıcı bir etkiye sahip olduğu bulguları elde edilmiştir.

The Effect of Asymmetric Information Under Structural Breakdown on Stock Return Playability: A Application in the BIST 100 Index
2021

Abstract:

The aim of this study is to reveal the impact of asymmetric information under structural breakdowns on the stock return game with the ARFIMA-FIGARCH dual long memory and the Markov Switching Regression models. In this regard, the study has taken into account the closing prices of the daily dollar for the period 04.01.2010-31.12.2018 of the BIST 100 Index, the purchase price margin and the total volume of the transaction data. Possible breaks in the variance of the return series in the study of Sanso vd. (2004) was studied by a breakthrough test; however, no structural breakthrough was detected. Therefore, without taking into account structural fractures, the most suitable game model for the stock return game series was studied with the ARFIMA-FIGARCH model, the most suitable model was found to be the ARFIMA(3x,4)-FIGARCH (1,d,1) model according to the broken student t distribution. In the study, the impact of asymmetric information on stock return game was studied by the Markov Switching Regression model. As a result, the purchase price margin has been found to have an increasing effect on the stock return game in both regimes. In addition, the findings have been found that the total volume of transactions of the amount is increasing the return rate of the stock in Regime 1; and in Regime 2 it has a reducing effect.
