美国论文代写-随机游走理论

美国论文代写

根据作者的观点,关于真实意义上的证券价格的随机游走理论有两个不同的假设:

  • 连续的价格变动是独立的。
  • 价格的变动在某种程度上是传统的。

根据这篇文章,一系列连续的价格变动足以说明价格变动分配的某些特定性质。如果范围内的真实情况不足以解释所涉及的财产,统计学家可以将一个独立的假设作为对现实的充分描述(Chen, 2010)。

对某一特定股票的连续价格变动的独立性,可能只是模仿一种完全不同于实际经济世界的价格机制和政治事件。

随机漫步理论的另一个假设是价格变动符合可能性分布(Chitenderu, Maredza和Sibanda, 2014)。然而,在这两个假设之间,独立性是最重要的。价格变动的分配模型被认为是对希望在这一领域从事实际工作的个人的重要信息。统计工具的强度通常与它的功能特性密切相关。

According to the author, the theory of the random walks regarding the security prices in genuine sense associates with two different hypotheses which are as follows:
The successive price alterations are independent.
The price alterations are conventional to some possibility distribution.
According to the article, a range of successive price alterations is adequate to account for some specific property of the distribution of price alterations. In case the real in the ranges is not adequate to explain for the property in question, the statistician may take an independent hypothesis as a sufficient description of the reality (Chen, 2010).
Independence of consecutive price alteration for a specific stock may simply imitate a price mechanism that is completely dissimilar to the actual world of economies along with the political events.

Another hypothesis of the theory of random walks is indicated to be the price alteration that conforms to possibility distribution (Chitenderu, Maredza and Sibanda, 2014). However, between the two hypotheses, the independence is the most significant. The model of the distribution of the price alterations is considered as important information to an individual who wishes to perform the practical job in this field. The strength of statistical tools is in general closely connected to the nature of data to which it is functional.

所有的图表理论认为,股票价格的过去行为被认为是预测股票未来走势的重要信息(Bei et al., 2014)。这些理论主要基于“历史重演”的原则。此外,根据该理论,以往价格行为的模式将倾向于在未来再次发生。根据这些图表理论,如果一个人仔细地分析了价格图表,个人就可以对价格行为模型有特定的安全性的理解,并且能够有效地预测特定安全价格的未来行为。此外,先前提到的理论可以有效地增加投资于股票市场的潜在利润(Fama, 1965)。

另一种随机漫步理论则提供了不同的看法。此外,根据随机游动的理论,未来安全价格水平的旅程可以更有效地预测一系列随机数据的收集过程。从统计学上讲,这个理论可以解释为,连续的价格变化是独立的,并且是相同的分散的随机变量。从一个简单的意义上说,这意味着价格变动的范围没有记忆;因此,之前的统计数据不能用于预测股票未来价格的准确方法(Borges, 2011)。教授更强调随机漫步理论,它是随机漫步模型的基础。在本文中,作者详细讨论了随机游动模型的理论。此外,作者还研究了随机漫步模型的实际有效性,并得出结论:数据似乎以一致的方式存在,并为理论提供了强有力的支持(Bougioukou, 2015)。文章的结论是,以前的图表的阅读可能是一个有趣的过去的时间。但是,这些不能为股票市场的投资者提供实际的价值。

All the Chartist theories assume that the previous behaviour of the stock price is considered as the important information and useful in predicting the future behaviour of the stock(Bei et al., 2014). The theories are mainly based on the principle “history repeat itself”. Moreover, according to the theory, the pattern of the previous price behaviour will be inclined to happen again in the future. According to these chartists theory, if an individual carefully analyses the price chart thoroughly, the individuals can develop an understanding of the price behaviour model with specific security and can efficiently anticipate the future behaviour of the specific security price. Moreover, the previously mentioned theory can be effective in increasing the potential profit from the investment in the stock market (Fama, 1965).

The other theory of random walks provides a different perception. Moreover, according to the theory of random walks, the future journey of a security’s price level can be more efficiently predict by the journey of a range of collected random numbers. Statistically, the theory can be explained in a way that successive price alterations are independent and identically dispersed random variables. In a simple sense, it implies that the range of price alterations has no memory; thus, the previous statistics cannot be applied to anticipate the future price of the stock in an exact method (Borges, 2011). The Professor provided greater emphasis on the random walks theory, which is underlying on random walks model. In this article, the author discussed the theory of the random walks model in a detailed way. Moreover, the author examined random walk’s model practical validity and concluded that the data seem to exist in a consistent way and provide strong support to the theory (Bougioukou, 2015). The conclusion of the article paper was that the reading of the previous chart might be an interesting past time. However, these could not provide the actual value to the investors of the stock market.

股票市场在本质上是剧烈波动的;因此,在对市场进行投资决策之前,分析股票市场的行为是很重要的。运用多种理论和原理对股票市场价格的行为进行评价,对某一特定股票的未来绩效进行有效预测。在这个问题上,尤金·法玛教授在很久以前就提供了扎实的概念知识(Agwuegbo, 2010)。此外,法玛教授所提出的理论和概念框架在这个时代仍然是相关的。教授充分强调了随机漫步理论。根据随机游动的理论,股票或证券价格水平的未来走势可以更有效地预测随机数字的范围。股票价格是随机变化的,因此,对股票价格的准确预测是不可能的(Banumathy和Azhagaiah, 2014)。在整个分配过程中,教授所提供的理论将被评估,并将与当前在股票市场做出决定的情景进行验证。

在文章的开头,作者对以往的普通股价格历史的程度提出了一个问题,可以用来对特定股票的未来价格进行有意义的预测。此外,根据作者的观点,有两种理论可以给出上述问题的答案。一些图表专家制定了第一个和第二个理论,这个理论被称为随机漫步理论(Beer, Watfa and Zouaoui, 2012)。有几种不同的图表理论支持预测股票未来的价格走势。然而,所有这些理论都很普遍,因为它们都创造了类似的基本预期。

The stock market is extensively volatile in nature; thus, it is important to analyse the behaviour of a stock market before making any decision on investment within the market. There are several theories and principles applied to evaluate the behaviour of the stock market price to make an effective prediction of the future performance of a specific stock. In this matter, Professor Eugene F. Fama provided solid conceptual knowledge in long before (Agwuegbo, 2010). Furthermore, the theories and conceptual framework given by Professor Fama are still relevant in this era. The professor provided adequate emphasis on the theory of random walks. According to the theory of random walks, the future journey of the price level of stock or security can more effectively predict by the range of collected random numbers. The stock prices use to change on a random basis and thus, to make any accurate prediction of the stock price is impossible (Banumathy and Azhagaiah, 2014). Throughout the assignment, the theories provided by the Professor will be evaluated and will be verified with current scenarios of making the decision in the stock market.

At the beginning of the article, the author kept a question about the degree of the previous history of common stock price which can be utilized to formulate a meaningful anticipation about the future price of that specific stock. Moreover, as per the author, there are two theories by which the answer of the question above can be given. Several chartists formulate the first and second theory which is referred to as the theory of random walks (Beer, Watfa and Zouaoui, 2012). There are several different chartist theories, which support in anticipating the future price behaviour of the stocks. However, all of these theories are common in the sense that they all create the similar types of basic anticipations.
