Herding behavior is typically described as the inclination of investors to follow the actions of others in their investment decisions. Herding represents a behavioral tendency in which investors rely on collective rather than private information. Herd literature shows that return jumps can serve as a representation of information arrival, leading to significant price changes. This proposition is introduced due to its potential impact on investor sentiment, assuming greater awareness among other investors as a factor related to the occurrence of herding. Furthermore, it is believed that, in conditions of negative market returns, market participants are more inclined to mimic the behavior of others due to the stress induced by the risk incurred. In the background of previous research, evidence indicates the occurrence of herd behavior on days with return jumps and negative returns. In this study, we investigated herding behavior and its asymmetry through the utilization of return jumps, employing the CSAD method. Under circumstances in which there were no occurrences of return jumps and without taking into account negative market returns, our research was unable to verify the existence of herding at the market level. Nevertheless, when return jumps and negative market returns were present, the occurrence of herd behavior was proven, and the asymmetry of herd behavior was also verified.

Southeast Asian countries have always been the focus of oil producers due to the increase in population and the trend of economic growth. In the last two decades, Indonesia has been prioritized as one of the new markets for Iran due to its high population and forecast to become the fifth largest economy in the world and the upward trend of energy demand. The purpose of this research is to investigate the capacities of Indonesia using the documentary library research method. Indonesia is a developing country and has an increasing economic and population growth trend, which is facing an increasing demand for energy. For this reason, this market is always the focus of major oil producers.The results of this research show that the refinery capacity of Indonesia's need for petroleum products in the form of joint venture or take-off method to create a sales chain in this country can increase its dependence on Iran. And as a result, more market share can be obtained and also the joint investment cooperation in the upstream development sector with Indonesian oil companies in the direction of developing its fields is also significant. The first question in this research is “what are the capacities of joint cooperation with Indonesia in the field of oil industry”, and the second question is “what are the capacities of joint cooperation between Iran and Indonesia in the field of oil industry?”
