作者Malkiel和Fama教授提供的关于random walk理论的理论为害怕的个人投资者提供了相当大的支持。然而,作者特别鼓励投资者了解随机漫步理论所面临的投资理论和投资技巧(DahiyaGaina, 2012)。因此,笔者主张对投资进行买入和持有策略,认为这是优化投资回报的最佳途径。

根据支持随机漫步理论和有效市场假说(EMH)的学者们的观点,股票的现有市场价格是复制完整的、可获取的信息,而证券的当前市场价格是其真实价值。这个想法对随机漫步理论很重要。如果目前的市场价格是股票实际价值的完美例证,那么没有分析可以洞察未来价格的变化(Dsouza和Mallikarjunappa, 2015)。

The random walk theory claims that it is not possible to constantly break the market, specifically in the short term, as it is not possible to anticipate the prices of stocks. The author of the book A Random Walk Down Wall Street Malkiel claims that the analysts or the professional advisors can add the minute or no value to the portfolios. According to the author, advisory services for the investment, earnings predictions and complex chart models are futile and useless.

The author Malkiel and the theory provided by Professor Fama regarding the random walk theory provide considerable support to the scared individual investor. However, the authors specifically encourage investors to be aware of the theories and techniques of investment that the random walk theory confronts (DahiyaGaina, 2012). Therefore, the author advocates the buy & hold strategy for the investment as he considered it as the best way to optimize the return on the investment.
According to the scholars who support random walk theory and efficient market hypothesis (EMH), the existing market price of a stock replicates the complete, accessible information, and the current market price of the security is its true value. The idea is significant for the random walks theory. If the present market price is a perfect illustration of the actual value of stock, then no analysis can deliver insight into where price will shift in the future(Dsouza and Mallikarjunappa, 2015).
