Abstract

In this study, the hypothesis of Samuelson 1965 which is as futures contract nears maturity the contract price volatility increases, is tested on Borsa Istanbul 30 index futures contracts for the period of 2005-2012. The examinations are conducted seperately on the basis of contract and over the entire period. Least squares regression and GARCH models are applied and in addition to time to maturity effect the effects of volume and open interest on return volatility are investigated. According to examination on the basis of contract, partially existence of inverse time to maturity effect is reached. On the other hand, it is reached that there is significant inverse time to maturity effect in all of the period. In this context, it is concluded that the Samuelson hypothesis is not valid in BIST 30 index futures contracts

En küçük kareler regresyon ve GARCH modelleri uygulanmış, vadeye kalan zaman etkisinin yanı sıra işlem hacmi ve açık pozisyonun getiri volatilitesi üzerine etkileri de araştırılmıştır. Kontrat bazında incelemelere göre, tersine vadeye kalan zaman etkisinin kısmen var olduğuna erişilmiştir.
