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。
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).
