英国论文延期：CAPM及其提出的金融理论
随着时间的推移，人们发现，还有其他经验证据对CAPM及其提出的金融理论提出了挑战。这也挑战了金融理论的基本假设。这些研究人员认为，CAPM对投资者来说不够理性。它也被认为是低效的。CAPM在项目评估、投资组合评估和管理、资本成本确定等方面得到了广泛的应用。在这些领域，CAPM被认为效率较低。

虽然CAPM中存在一些问题，但由于其简洁性和直观性，它所呈现的理论表示在当今时代仍然更常用。由于模型的可扩展性，更多相同模型的扩展已经开始使用。它基于两个基本假设，这两个假设也适用于当前的投资者。首先，它理解证券市场是具有竞争性的，它们是尽可能有效和普遍分布的，以支持它们的竞争力。

Over time it was observed that there are other empiricalevidences that challenged CAPM and the finance theory understanding that it presented. This challenges the very basic assumptions on finance theories as well. The CAPM as argued by these researchers is supposed to not be rational enough for investors. It was also considered as inefficient. CAPM was used critically for cooperating project valuations, portfolio assessment and management, cost of capital determination etc. Now in these areas, CAPM was called out to be less efficient.

Although there were issues in CAPM, the theoretical representation that it presents is more often used in current times still, because of its simplicity and intuitiveness. Many more extensions of the same model have come into use because of extensibility of the model. It works on two basic assumptions which holds good for current day investors, too. Firstly, it understands that securities markets are competitive and that they are as efficient and as universally distributed as possible to support their competitiveness .
