Impact of Calendar Anomalies on Stock Exchange Markets: Intercountry Analysis
- The Efficient Market Hypothesis would lead one to believe that stock markets are perfectly efficient and that abnormal/ deviant average returns are not possible. However, the existence of calendar anomalies empirically shows how specific periods during a week, month and year can influence the average returns in the stock markets. Research from scholarly journals and books, industry-related news sources, and industry-experts shows the occurrence of various calendar anomalies in global markets that led to unbalanced average returns and confronted the fundaments of the Efficient Market
Hypothesis.
