Abstract

The aim of this study is to analyze the Weekend and January effect in the Ghana Stock Exchange (GSE) using daily closing prices of GSE-All Share Index (ASI) and Composite Index (CI) between the period of January 4th, 2005 and December 31st, 2013. The dataset covers the period of 2005 to 2010 (6 years) for the ASI and 2011 to 2013 (3 years) for the CI. The following results are obtained based on a parametric regression using dummy variables. First, no weekly effect or anomaly is documented for both GSE-ASI and GSE-CI. Second, market abnormalities are captured for both GSE-ASI and GSE-CI over their respective entire periods. However, no consistent April effect is found for ASI when the period was segregated into two periods of three years. The April effect is uncovered for the GSE-ASI at 5% significant level while the January effect is found for the GSE-CI at 1% significant level.

본 연구의 목적은 가나증권거래소 종합지수를 바탕으로 가나 증권 시장에서 주말 효과 및 1월 효과가 나타나고 있는지를 분석하고자 하는 것이다. 이를 위해 가나 증권시장에 상장된 기업을 대상으로 2005년 1월 4 일부터 2013년 12월 31일까지 9년간의 일별종가와 종합지수를 나타내는 ASI 및 CI를 토대로 회귀분석을 이용하여 두 효과를 검증하였다. 회귀분석 결과에 따르면 가나 증권 시장에서는 주말효과가 나타나지 않아 선행 연구 결과와 다르게 나타났으며 이는 연구기간과 연구 자료가 다르기 때문인 것으로 사료된다. 월간효과의 회귀 분석 결과, ASI가 사용된 2005년부터 2010년까지 6년의 기간 전체를 대상으로 분석한 결과 4월 효과가 나타났으며, ASI가 사용된 기간을 3년을 기준으로 두 개의 기간으로 구분하여 분석한 결과 2005년부터 2007년까지의 기간은 4월 효과가 보이지 않지만 2008년부터 2010년까지 기간의 경우에는 4월 효과가 나타났다. CI가 사용된 2011년부터 2013년까지 기간의 경우에는 1월 효과가 존재하는 것으로 나타났다.
