Combining with Monte Carlo Simulation, it can price CDO effectively.

ABSTRACT This research aims at evaluating the risk of home loan, financial institutions generally think that makes enterprises to grant the loan and have a big risk in recent years , turning to and developing consumption financial transaction one after another, the personal home loan has already become the strategic point of every financial institution.

­^¤å´£­n¡G A utility function model of individual credit card holder based on their spending behavior is constructed in this research. An accumulation of the individual utility of three different risk attitudes of cardholders may be useful for promoting the profits of credit card business for banks. Due to the privacy of cardholders and the lack of real data, a questionnaire sampling is used to collect data for this study. A result of this experimental study indicates that credit card holders with a different sex, age, level of education, asset condition, seniority, and occupation have different risk tendency. Based on 249 effective samples in this research, credit card holders who belong to females, teenagers, relatively low educated, without real estate, middle seniority, and relatively volatile occupation are more risk seeking. Relatively risk seeking credit card holders have the tendency to make use of their revolving credit and to borrow cash or to buy financial products with their credit cards. For those with three different risk attitudes, their default of credit card loans are not significantly different. The finding indicates relatively risk seeking cardholders may contribute more profits to the credit card business for banks. A risk attitude classification model built by artificial neural network has also been developed. The model may assist banks' administrators using their applicants' demographics to distinguish their risk attitude for approving an appropriate credit limit for a cardholder's expenditure to promote the total credit card profit for banks.

This paper attempts to find the relationship between momentum and firm¡¦s credit rating. According to Avramov¡¦s (2007) finding, there is a strong link between momentum and firm credit rating in US. In this paper, the similar phenomenon is proven existing in Taiwan stock market. Momentum profitability is large among low-grade firms, but it is insignificant among high-grade firms. The source of momentum profits is from operating performance, financial performance, volatility and illiquidity. For loser (winner) stocks in the low rating category, profit margins, sales growth, operating cash flows, and interest coverage decrease (increase) over the formation and holding periods, while illiquidity and volatility increase (decrease). As the market observes the deteriorating (improving) conditions, there is a pressure to sell (buy) losers (winners), which enhances gains among high risk winners and losses among high risk losers.
