Introduction/Main Objectives: This study aims to examine the role of heuristics behavior towards the formation of fundamental and technical anomalies in the capital market. Besides, this study also aims to examine the role of fundamental and technical anomalies on investment performance. Background Problems: EMH is not always able to explain all events or phenomena so that it still raises questions and gives results from research that do not meet the expectations, and in the end, this phenomenon is categorized as a market anomaly. This study investigates whether heuristics have an effect on fundamental and technical anomalies and whether the anomalies have an effect on investment performance. Novelty: There is no research that uses hindsight variables incorporated into heuristics; therefore, this study confirms that the indicators used in hindsight measurements are appropriate for measuring what will be measured. Previous research did not involve hindsight in the heuristic category. Research Methods: Data management is done by using SEM with the help of the Warp-PLS analysis tool. Mediation exploration testing with the VAF (Variance Accounted For). Findings/Results: The results of the study show that heuristics (availability, representativeness, and hindsight) are proven to be one of the factors that cause fundamental and technical anomalies in the capital market except for availability heuristics. Conclusion: A large number of anomalies in the capital market do not stop investors from continuing to invest so that at a certain level of investors are satisfied with their investment performance because they use heuristics in an efficient way.
