摘要

本研究考察了尼泊尔股票市场的羊群形成。本文采用包含二次变量的线性回归模型,对个体股票收益离散度与市场总收益之间的关系进行建模,以寻找羊群行为。这项研究没有发现羊群的存在。相反,当羊群的存在对看跌和看涨趋势进行测试时,羊群形成在看涨趋势中被检测到。该研究支持了尼泊尔股票市场容易出现行为偏差导致定价效率低下的观点。研究结果可以帮助制定政策,以保护散户投资者免受这些行为偏差带来的下行风险。

Herding to Market Consensus: An Empirical Investigation of its Presence in Nepal Stock Exchange
The study examines herd formation in Nepalese equity market. The study uses linear regression models including quadratic variant to model the relationship between return dispersion of individual scrips and aggregate market return for finding the herding behavior. The study does not find presence of herding. On the contrary, when presence of herding is tested for bearish and bullish trend, herd formation is detected in bullish trend. The study supports the notion that Nepalese equity market is prone to behavioral biases leading to pricing inefficiencies. The findings of the study can be helpful to make policies to protect retail investors from downside risk arising from these behavioral biases.
