Abstract

From the perspective of the mediation effect, this paper investigates whether institutional investors adjust their portfolios according to the listed companies earnings surprise. We find that the portfolio adjustments by institutional investors exert the mediation effect on the relationship between earnings surprise and stock price volatility. Institutional investors actively manage their portfolios in the rising market, which induces the stock price volatility; while they less adjust their portfolio in the falling market, the volatility declines. This paper helps understand the role of institutional investors in the fluctuation of stock prices, and provides a new basis for decision making of regulatory administration.
