代写美国毕业论文：投资者的非理性行为

根据经典经济理论，投资者可以获得有效的信息并加以处理。这里假设投资者可能无法获得所有信息，但无论他们获得什么信息，他们都能够有效地处理信息。但是可以看出，投资者做出的决定往往是不正确的。投资者普遍过于自信。处理完信息后，他们对自己的决定过于自信，而且他们是正确的。可以举出一个例子，即面试官根据面试做出对某人的判断。面试官认为，他们在面试后可以对个人做出合理的假设。据观察，个人过度自信。因此，投资者倾向于做出偏见，而不是做出理性和无偏见的决策。投资者往往对他们的决策过于乐观。他们倾向于高估他们决策成功的可能性，并低估他们决策失败的可能性。过度自信导致对股票做出错误决定，投资者转向过度交易。上述三种现象可以用来解释投资者的非理性行为，可以作为证明投资者行为的工具。

代写美国毕业论文：投资者的非理性行为

According to the classical economic theory investors get available information and process them efficiently. Here the assumption is that investors may not be able to get all the information but whatever information is available to them, they are able to process it efficiently.  However it can be seen that the decision made by the investor is often not correct. Investors are generally overconfident. After processing the information they are too confident about their decision and they are right. An example can be given is that of interviewer making judgment about a person based on an interview. Interviewers believe that they can become reasonable assumption about the individual after taking his or her interview. It has been observed that individuals have overconfidence inbuilt in them. Thus instead of making rational and unbiased decisions investors tend to be biased. Investors tend to be overoptimistic about their decisions. They tend to overestimate the chances of success of their decision and underestimate the chances of failure of their decisions. Overconfidence results in making wrong decision about the stock and investors turn to excessive trading. The above three phenomenon can be used to explain irrational behaviour of the investors and can be used as tools to justify the behaviours of the investors.
