FIAPARCH MODELİ İLE DÖVİZ PİYASASI ETKİNLİĞİNİN TEST EDİLMESİ
2021

Abstract:

Etkin Piyasa Hipotezine göre, finansal varlık fiyatları piyasada yer alan bütün bilgileri eksiksiz ve eş anlı olarak yansıtmaktadır. Yani piyasaya ulaşan tüm bilgiler eş anlı ve doğru olarak finansal varlık fiyatlarına yansıyorsa, o piyasanın etkin bir piyasa olduğunu ifade etmektedir. Finansal varlık fiyatı, piyasada bulunan tüm bilgileri yansıttığı için geçmiş varlık fiyatını kullanarak gelecekte alabileceği fiyatı öngörebilmek mümkün olmamakta ve fiyatlar rassal olarak oluşmaktadır. Çalışma, Türkiye döviz piyasasının etkinliğini araştırmak için yapılmıştır. Euro / TL ve Yuan / TL döviz kurlarının, 20 Mart 2012 ile 9 Nisan 2021 tarihleri arasındaki günlük satış fiyatları üzerinden çalışma gerçekleştirilmiştir. Volatilitede uzun hafızanın varlığı, asimetrik koşullu değişen varyans modeli olan FIAPARCH modeli kullanılarak ortaya çıkarılmaya çalışılmıştır. Euro / TL ve Çin Yuanı / TL döviz kurları getiri serilerine ait FIAPARCH model sonuçlarına göre, uzun hafıza değeri olan “d” her iki döviz kuru getiri serisi volatilitesinde de uzun hafızanın olduğunu göstermektedir. Bu sonuç Türkiye döviz piyasasının etkin bir piyasa olmadığını göstermektedir. Asimetri parametresi olan γ, anlamlı ve negatif değerde tespit edilmiştir. Pozitif bilgi şoklarının volatilite üzerinde negatif bilgi şoklarına göre daha baskın olduğu anlamına gelmektedir.

The FIAPARCH model tested the effectiveness of the turnover market
2021
Author:  
Abstract:

According to the Effective Market Hypothesis, the financial asset prices reflect all the information on the market in a complete and simultaneous way. Thus, if all the information that reaches the market is simultaneously and accurately reflected in the financial asset prices, it means that the market is an effective market. The financial asset price reflects all the information on the market, and it is impossible to predict the price it can get in the future using the previous asset price, and the prices are racial. The study was done to investigate the effectiveness of the foreign exchange market in Turkey. The work was carried out on the daily sales prices of the Euro / TL and Yuan / TL currencies between 20 March 2012 and 9 April 2021. The presence of long memory in volatility has been tried to be revealed using the FIAPARCH model, an asymmetric conditional variable model. According to the FIAPARCH model results of the Euro / TL and China Yuan / TL currency return series, the "d" with a long memory value shows that both currency currency return series volatility also has a long memory. This results indicate that the foreign exchange market is not an effective market. The asymmetrical parameter γ is identified in meaningful and negative values. This means that positive information shocks are more prevalent over volatility than negative information shocks.

Testing The Exchange Market Efficiency With The Fiaparch Model
2021
Author:  
Abstract:

According to the Efficient Market Hypothesis, financial asset prices reflect all the information on the market completely and simultaneously. In other words, if all the information reaching the market is reflected on financial asset prices simultaneously and accurately, it means that the market is an efficient market. Since the price of the financial asset reflects all the information available in the market, it is not possible to predict the future price using the past asset price and the prices are determined randomly. The study was designed to investigate the efficient of Turkey foreign exchange market. The study was carried out on the daily sales prices of Euro / TL and Yuan / TL exchange rates between 20 March 2012 and 9 April 2021. The existence of long memory in volatility has been tried to be revealed by using the asymmetric conditional variance model, the FIAPARCH model. According to the FIAPARCH model results of the Euro / TL and Chinese Yuan / TL exchange rate yield series, the long memory value “d” indicates that there is a long memory in both exchange rate return series volatility. This result shows that there isn't an efficient market of Turkey foreign exchange market. The asymmetry parameter γ was found to have a significant and negative value. It means that positive information shocks more dominant on volatility than negative information shocks.
