Ramadan fasting is one of the most celebrated religious rituals in the world. Ramadan is a positively perceived feast (in the same way as other feasts like Christmas, New Year, etc.); therefore, we can anticipate it should positively affect investor psychology.

Academic research confirms this speculation. Equity returns during Ramadan are almost nine times higher and less volatile than during the rest of the year. A simple market timing strategy could be therefore created by holding an equally weighted basket of ETFs, from countries with a large Muslim population during the month of Ramadan and staying in cash during the rest of the year. Due to its simplicity, this strategy could be easily incorporated into various portfolios.

Fundamental reason

Academic research postulates that the euphoria derived from Ramadan could influence investor behavior in Islamic markets. The upbeat mood during Ramadan leads to positive investor sentiment and has a positive valuation effect on equity markets in Islamic countries.

The investment universe consists of countries for which stock market index data are available and in which the proportion of the population professing Muslim faith exceeded 50%. Most of the countries could be easily tracked via index ETFs. The research paper we use as an example uses 14 Muslim countries.

Ramadan is the ninth month in the Islamic calendar, which is based on the motion of the moon. The Ramadan month could be calculated by using the information on the lunar phases and sunset times from the astronomical calendar or information about Ramadan dates from various public sources.

The trading strategy is simple. The investor holds an equally weighted portfolio of ETFs during the Ramadan month. He/she is otherwise invested in cash.

Bialkowski, Etebari, Wisniewski: Piety and Profits: Stock Market Anomaly during the Muslim Holy Month
- Abstract

Observed by more than 1.5 billion Muslims, Ramadan is one of the most celebrated religious rituals in the world. We investigate stock returns during Ramadan for 14 predominantly Muslim countries over the years 1989-2007. The results show that stock returns during Ramadan are almost nine times higher and less volatile than during the rest of the year. No discernible difference in trading volume is recorded. We find these results consistent with a notion that Ramadan positively affects investor psychology, as it promotes feelings of solidarity and social identity among Muslims world-wide, leading to optimistic beliefs that extend to investment decisions.

Almudhaf: The Islamic Calendar Effects: Evidence from Twelve Stock Markets
- Abstract

This paper investigates the Islamic calendar seasonal anomalies in the stock returns of twelve countries where the majority of the population are Muslims. We show empirical evidence of statistically significant Islamic calendar seasonal effects in all twelve countries of our sample. We document evidence of positive and statistically significance returns in the month of Ramadan in Jordan, Kuwait, Pakistan and Turkey. Our results provide some evidence against market efficiency.

- Abstract

In spite of the important role religion plays in peoples’ lives, its impact on financial markets is seldom researched. This study examines the effect of religious experience during the Muslim holy days of Ramadan and Ashoura on the daily returns and trading volumes of 17 Muslim financial markets. Muslim holy days are especially conducive to isolating the elusive effect of faith and decoupling it from potential contaminants. The study documents statistically significant drops in the trading volume and changes in daily stock returns associated with religious experiences on these holy days. The effect on returns is not unidirectional as Ramadan yields a positive impact on daily returns while Ashoura is associated with a negative effect. Ramadan’s more sacred days are associated with a higher magnitude effect culminating on its holiest day,Ramadan 27th. The study utilizes the heterogeneity of worship intensity within the month of Ramadan to validate that the documented effect is indeed a result of religious experience rather than non-faith aspects of the holy days.
