As per the findings of the study, it can be observed that in India majority of studies have confirmed the non-existence of herding behavior. Half of the studies conducted in Pakistan confirm the existence of herding behavior while remainder confirm non-existence of herding behavior. Similar results were observed in Sri Lanka as well. However, majority of studies in Taiwan and Indonesia and all the studies of Vietnam have provided results for the existence of herding behavior. Thereby this study identifies several open issues for future research. Future studies that deal with time-series price data could employ empirical methodologies that allow for time-variation in parameter values. It is also important to know whether it is the same investors that herd over time, and why: are the reasons behind herding the same over time?
