Advances in computational finance and its application in grid computing

目前(2008年9月至10月)金融市场的混乱，即使在美国和其他国家的政府干预在很大程度上拖累了全球经济之后。问题的一些根本原因是：贪婪和竞争使许多基金经理在没有充分了解这些工具在动态的市场环境中的行为和反应的情况下，浮动复杂的金融工具(信用违约互换、债务抵押债券等)；美国的次级抵押贷款热潮；以及金融机构未能不断分析其业务所涉及的风险。市场竞争的加剧推动了对金融中复杂和计算密集型问题的更快、更准确的解决方案的研究。期权是市场上常见的衍生品之一。期权定价是金融领域主要研究问题，如风险价值(VaR)、投资组合优化和复杂衍生品等。这一努力创造了一个极具挑战性的研究领域，称为计算金融。

Current (Sept.-Oct., 2008) chaos in the finance market even after government intervention in USA and other countries has brought down the global economy to a great extent. Some of the root causes of the problems are: the greed and competition have made many money managers to float complex financial instruments (credit default swap, collateralized debt obligation etc) without sound understanding of the actions and reactions of these instruments in the dynamic market environment; sub-prime mortgage boom in USA; and financial institutions failing to constantly analyze the risk involved in their business. Increasing competition in the market drives the research for faster, and more accurate solutions for problems in finance that are complex and computationally intensive. Options are one of the common derivatives in the market. Pricing options is the backbone of major research problems in finance such as value at risk (VaR), portfolio optimization and complex derivatives. This drive has created a highly challenging area of research called computational finance.
