Between 2002 and 2007, gross notional amounts outstanding grew from below S2 trillion to nearly S60 trillion. The recent crisis has revealed several shortcomings in CDS market practices and structure. In addition, management of counterparty risk has proved insufficient, as has in some instances the settlement of contracts following a credit event. However, past problems should not distract from the potential benefits of these instruments. In particular, CDSs help complete markets, as they provide an effective means to hedge and trade credit risk. CDSs allow financial institutions to better manage their exposures, and investors benefit from an enhanced investment universe. The purpose of this paper is to present a complete and practical exposition of the CDS market and to explore how the development of the CDS market has played an important role in the credit risk markets. Currently, the CDS market is transforming into a more stable system. Various measures are being put in place to help enhance market transparency and mitigate operational and systemic risk. In particular, central counterparties have started to operate, which will eventually lead to an improved management of individual as well as system-wide risks.展开更多

This study examines the value relevance of earnings when earnings are transitory, i.e., there is great variability in earnings. It hypothesizes that the relationship between earnings and security returns worsens when earnings are transitory and this robustness is country specific. The dataset consists of more than 1,100 French firm-year observations over a nine year period. Empirical results show that when earnings are transitory, investors pay more attention to operating cash flows and less attention to earnings, a result indicating that investors penalize firms with unstable earnings. These results should be of great importance to financial analysts, investors and bankers for investing and credit decisions, especially after the recent global financial crisis.展开更多

At the present stage, the long-effect mechanism for investor education is not only a demand of China＇s securities market on its healthy development, but also an objective reality that China＇s investor education is necessary to confront with. For these reasons, it is necessary for China to deepen investor education, expand investor education platform, strengthen risk prevention, and take initiative to build up a multi-level investor education system, and ultimately establish and improve a long-effect mechanism for investor education, so as to ensure the stable, harmonious and order development of China＇s Securities market in futures.展开更多

In the models, expected returns and uncertainty matrix of views are redefined and the views are formulated by fuzzy approaches suitably. Then the models are tested with data from Chinese financial markets. Empirical results show that the fuzzy random views model performs the best, and both the fuzzy models are better than the traditional ones, demonstrating that the fuzzy approaches can contain more information in the views and measure the uncertainty more correctly.展开更多
