In the study, 11 countries in the North Hemisphere and 6 countries in the South Hemisphere have been used. Analysis period covers the years between 2000- 2010. According to descriptive statistical results, stock exchanges of countries might be affected by seasonal changes. This interaction level differs among countries. Despite this, according to hypothesis testing results, the seasonal division of years composing analysis period as spring-summer and autumn-winter in the form of two independent sample groups does not give significant results statistically. Two independent samples come from a universe with the same distribution. © EuroJournals Publishing, Inc. 2012.eninfo:eu-repo/semantics/closedAccessBehavioral FinaceInvester SentimentSeasonal Affective DisorderSocial MoodStock ExchangesArticle831848N/A
