Abstract

Calendar anomalies, including the day-of-the-week effect, week-of-the-month effect, and January effect, persistently contest the efficient market hypothesis (EMH), which asserts that asset prices completely incorporate available information. This study reviews previous research to explore why these predictable patterns persist despite technological progress and market transparency. By combining perspectives from EMH, behavioral finance, and the adaptive market hypothesis (AMH), the study explains the temporal variability of these anomalies across different market contexts. Results demonstrate that investor sentiment, cognitive biases, and socio-cultural influences largely contribute to their persistence. The discourse encompasses practical implications for investment strategy, portfolio management, and regulatory surveillance, particularly highlighting Shariah-compliant and emerging markets where anomalies may display unique attributes. Investors, mutual funds, and brokers can gain benefit through generating higher returns.

Abstract

The main problem faced by Small and Medium Enterprises (SMEs) in the cosmetics and perfume sector is the lack of a deep understanding of product knowledge aspects and halal product standards, especially in the context of the majority Indonesian Muslim market. This community service activity (PKM) aims to increase the entrepreneurial capacity of students and partner SMEs through intensive training on branding, product knowledge, and halal certification processes for ablution-friendly perfume products. The method of implementing activities includes three stages: (1) Socialization and education about the importance of halal certification and the concept of ablution-friendly perfume; (2) Technical training on the preparation of brand identity and digital marketing strategies; and (3) Direct assistance in improving the quality of SME Partner products. The results achieved were a significant increase in the understanding of participants (students and SMEs) by 35% regarding halal and branding aspects. In addition, SME Mitra has successfully identified and reformulated the Unique Selling Proposition of their products, namely perfumes that meet the criteria of 'ablution-friendly'. This activity succeeded in creating synergy between academics and business actors in producing competitive products in the halal market.
