Behavioral biases and portfolio choice
نویسنده
چکیده
We investigate the way investors react to prior gains/losses. We use a new and unique dataset with detailed information on investors’ various components of wealth, income, demographic characteristics and portfolio holdings identified at the stock level. We test the theory of loss aversion against the alternative provided by standard utility theory and the house-money effect. We show that, on a yearly horizon, investors do not behave according to loss aversion and more in line with standard utility theory or the housemoney effect. We also show that investors do not suffer from the mental accounting bias. Investors consider wealth in its entirety and risk taking in the financial market is affected by gains/losses in overall wealth, financial wealth and real estate wealth.
