  • Abstract
    This paper analyzing the case of Sinopec, we study the relationship of beta between market weight of the listed companies and the beta of the residual portfolio. The result shows that the market weight and the cost of capital changes in the same way. But the relation of the market weight and the beta of the residual portfolio changes in a reverse way. The market weights influence the beta, and lead to a reduction in estimates of the cost of capital for small cap firms.
