Trading Opportunities You Missed on the Swedish Equity Market : An Analysis of the Persistence of Calendar Anomalies

Sammanfattning: This Study uses a period between 1939-2017 to analyse calendar anomalies on the Swedish equity market. We test whether calendar anomalies’ return deviates from the return of ordinary trading days. Our result shows that the day of the week effect, weekend effect, turn of the year, turn of the month and holiday effect have had an impact on the daily rate of return, both domestic and abroad. Similar to international markets the calendar anomalies in Sweden start to be less prominent during 1980’s. Also, our result displays that, since the 1970’s, UK holidays have had a negative impact on the daily return in Sweden. In contrast, American holidays have since the 2010’s had a positive impact. Turn of the year and turn of the month in Sweden have been more clustered around the first trading day of the year and month, compared to studies on other equity markets. Negative returns on Tuesdays, rather than Mondays, do also distinguish Sweden’s equity market relative to other markets.
