The Effect of Attention on Buying Behavior During a Financial Crisis : Evidence from the Taiwan Stock Exchange

We confirm that investors in different categories have different trading patterns caused by attention-grabbing factors.

Individual investors are net buyers of losers whereas institutional investors are net buyers of winners. Unlike institutional investors, individual investors also regard volume as a conditional attention-grabbing factor. We also find that attention-driven buying behavior is mitigated by the financial crisis of 2007, which indicates that the buying behavior of investors is less emotional during a period of financial crisis
