Abstract
This study aims to investigate the presence of feedback trading strategies among investors in the "Refah Coin Deposit Certificate" as a commodity-based financial instrument, as well as to analyze the symmetry or asymmetry of return volatility in response to market news. For this purpose, the Santana and Waldany (1992) model was employed to test for the existence of feedback trading, while the GJR-GARCH model was used to examine asymmetric responses of returns to positive and negative news. Daily data covering the period from February 22, 2016 to April 21, 2025were analyzed. The results indicated an asymmetric reaction of returns to market news, with positive news having a greater impact compared to negative news. However, no evidence of feedback trading behavior was found among investors in this market. Therefore, it can be concluded that investors have primarily focused on fundamental factors rather than short-term market trends or emotional reactions. Accordingly, it is recommended that investors pay more attention to fundamental and economic variables in their decision-making processes and avoid speculative or reactive trading strategies.
