Abstract
The purpose of this paper is to analyze the real-time responses of stock prices, volume, and order submission behavior across investor groups to 2894 on-air stock reports from 9:16 a.m. to 1:15 p.m. during regular trading hours from 10/11/2010 to 12/31/2010 in Taiwan. First, positive (negative) reports move stock prices upwards (downwards) in real time, accompanied by increasing trading volume. However, the observed price movements are short-lived and vanish 14 days afterwards. Second, responding to the reports, individual investors trade more actively and aggressively than institutional investors do. The overreaction of individual investors is responsible for the observed price movements.
