請問關於emotional biases這樣寫有沒有哪裡需要加強的謝謝 1. Overconfidence: the bias shows investors to think they know more than anyone regarding the company they hold. Richard thinks he knows more than other investors, which indicates overconfidence bias; 2. Endowment: the bias shows investors to value more the positions they hold. Richard thinks the company is a good investment and doesn't consider other possibilities which indicate endowment bias; 3. Status quo: the bias shows investors to stay with the same investment without consideration of other investments. Richard expects the company will continually be a good investment in the future, which indicates status quo bias.
