Using Taiwanese intraday order-level and execution data and following the
methodology, proposed by (Choe et al., 2005), we investigate whether domestic investors have an edge over foreign investors in trading domestic stocks in the Taiwan stock market. Firstly, we find that foreign investors pay more than domestic investors when they buy and receive less when they sell for large trades.Secondly, foreign investors are more at a disadvantage when they trade more.Thirdly, adopting an event-study approach, we show that foreign investors trade more on intra-day momentum than domestic investors.
