After the establishment of the Financial Control Law, great changes have taken place in the banking industry. In addition, the headwinds in the global economic environment has reduced the interest margin for banks, and this has become a key issue banks need to tackle in order to survive and develop. For this reason, the wealth management business has significantly increased the sales revenue of banks, and gradually become one of the key business sector in the banking industry. This study investigates the impact of customers’ characteristics on the demand for various investment products using the data from a branch of a commercial bank in the central area of Taiwan. This study mainly establishes two main hypotheses as follows: Hypothesis 1: The risk attributes of investors are unrelated to the preferences for financial products. Hypothesis 2: The risk attributes of investors are unrelated to investment sentiment, risk tolerance and expected returns. Finally, by testing the above hypotheses this study provides some useful guidelines for investors as well as the employees in the wealth management sector of banks, hoping to create a win-win situation for both.
