An Application of the Weak Form of the Efficiency Hypothesis on the Saudi Arabia Stock Market after Tadawul
Abstract
The aim of this study is to test the efficiency of the Saudi Stock Market (SSM) after “Tadawul” (the entity responsible for operating the SSM). The weak form of the efficiency theory was applied to test the SSM efficiency. The SSM daily stock price returns index was examined using autocorrelation and the run test of randomness from January 1st 2007 to March 18th 2007 (before Tadawul) and from March 19th 2007 to May 29th 2007 (after Tadawul). The results suggest more investigation to be done on the SSM behavioral finance and under reaction and overreaction split to confirm the SSM “efficiency”Submission of an article implies that the work described has not been published previously (except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, will not be published elsewhere in the same form, in English or in any other language, without the written consent of the Publisher.
