毕业论文代写
多年来，法玛教授提出的随机漫步理论已经受到公众的关注。有几位研究学者在研究这个问题。许多科学研究都是通过开放许多实验来证明其重要性的。有效市场的概念可以分为两部分。第一个想法是，股票的回报率在一个有效的股票市场是随机的。此外，第二种观点认为，股票市场的参与者无法获得超额利润(Dunham, 2013)。自随机漫步理论和有效市场假说成立以来，许多学者对这一理论进行了研究，并在现代金融研究和实证领域中探寻了这一理论的相关性。
法玛教授撰写的研究论文在当代投资情景中仍有一定的借鉴意义，一些学术学者仍在研究论文中提出的理论。随机游走理论被认为是重要的金融理论，它为市场提供了重要的视角。它支持证券市场的长期投资，而不是依赖于股票市场的投机性交易。随机漫步理论并不依赖于股票市场的基本面分析，因为它认为证券价格是非常难以控制和难以管理的。因此，对未来安全价格的预测是不可能的。通常情况下，预测是正确的，但这是机会的因素。此外，投资决策不能以概率为基础。根据随机漫步理论，过去的安全性能与未来的价格没有任何关系，价格变化是独立的，不能通过股票过去的表现来预测。几位学者就股票市场效率问题进行了探讨，并对这一专题进行了几项研究。随机漫步理论认为，股票价格数据似乎以一致的方式存在，股票的价格水平可以通过一系列随机数字的路径得到更有效的预测。
Over the years, the theory of random walk presented by Professor Fama has undergone public scrutiny. There are several research scholars who worked on this matter. Various scientific research studies are conducted by opening many trials which are made to demonstrate its importance. The idea of the efficient market can be divided into two parts. The first idea is that the return from the stock is random in an efficient stock market. Moreover, the second idea is that the participants of the stock market cannot earn a surplus profit (Dunham, 2013). Since the inception of the random walk theory and efficient market hypothesis, many scholars work on this theory and search the relevance of this theory in modern finance study and empirical field.
The research article written by Professor Fama is still relevant in the contemporary investment scenarios, and several academic scholars still work on the theories presented in the paper. The random walk theory is considered as the critical finance theory, and it provides significant insight of the market. It supports long-term investment in the security market instead of depending on the speculative daily trading in the stock market. The random walk theory does not rely on the fundamental analysis of the stock market as it states that the security price is immensely unruly and unmanageable. Thus, the prediction of the future price of security cannot be possible. Often the prediction can be true, but that is the factor of chance. Moreover, the investment decision cannot be taken based on probability. According to the random walk theory, the past performances of security have not any connection with its future price, and the price changes are independent and cannot be predicted by the past performance of the stocks. Several academic scholars have addressed the issues regarding the stock market efficiency and also conducted several research works on this particular topic. The random walk theory suggests that the stock price data seem to exist in a consistent way and a stock’s price level can be more efficiently predicted by the path of a range of collected random numbers.
