讲座主要内容：

A theoretical model is developed to study   investors' trading behaviour in the presence of large   shareholders' influence on a firm's equity performance. We show that, for a good   stock, large   shareholders may invest higher proportion of their wealth into the firm than small investors, and smart small   investors may invest more heavily than those naive small investors.

Insight is also cast into the impacts of board   structure on firm's equity when the firm is with several large influential   shareholders: (i) the large shareholders collude in trading, and   each tends to invest more aggressively in the companion of other large   shareholders, and (ii) firms with sole ownership can outperform those with   dispersed ownerships, would the impact coefficient of the former case exceed   or coincide with the aggregated impact   coefficients of the latter.
