HASAN AĞAN KARADUMAN

Abstract:

The question of whether the price and return series of a stock market exhibit a predictable and tractable pattern is always of interest in both theory and practice. After a brief overview of the literature on market efficiency, the stylized facts about the pre-global crisis, crisis and post-global crisis daily returns of Turkish stock market are explored at the statistical level as an example of the behavioural change in stock market of an emerging country. The weak-form market efficiency is also addressed using a range of statistical and econometric methods, namely unit root tests, variance-ratio tests, testing some anomalies which may falsify the stock market efficiency. The findings indicate there exists some form of deviations from the efficient market hypothesis during the global crisis period.
