Random walk or Non-random walk for forex

Introduction
The great debate continues between random walkers and non-random walkers. Two competing books best represent these theories. Originally written by Burton Malkiel in 1973, A Random Walk Down Wall Street has become a classic in investment literature. Malkiel, a Princeton economist, argues that price movements are largely random and that investors cannot outperform major indices.

Written by Andrew W. Lo and A. Craig MacKinlay in 2001, the appropriately titled A Non-Random Walk Down Wall Street provides the counter-argument. Lo, a professor of finance at MIT and MacKinlay, a professor of finance at Wharton, argue that price movements are not so random and that there are predictable components. Let the battle begin!

With "random walk," Malkiel claims that price movements in stocks are unpredictable. Due to this random walk, investors cannot consistently outperform the market as a whole. Applying fundamental analysis or technical analysis to market time is a waste of time that will simply lead to poor performance. Investors would be better off buying and holding an index fund.

Malkiel offers two popular investment theories that correspond to fundamental analysis and technical analysis. On the fundamental side, the "Firm Foundation Theory" argues that shares have an intrinsic value that can be determined by discounting future cash flows (earnings). Investors can also use valuation techniques to determine the true value of a security or market. Investors decide when to buy or sell based on these valuations.

On the technical side and Forex Signals the "castle in the air theory" assumes that successful investing depends on behavioral finance. Investors must determine the mood of the market: bull or bear. Valuations are not important because a security is only worth what someone is willing to pay for it.

The random walk theory agrees with the semi-strong efficient hypothesis in its claim that it is impossible to consistently outperform the market. This theory argues that stock prices are efficient because they reflect all known information (earnings, expectations, dividends). Prices adjust quickly to new information and it is practically impossible to act on this information. Also, the price moves only with the advent of new information and this information is random and unpredictable.

In short, Malkiel attributes any superior performance success to the lady's luck. If enough people try, some are likely to outperform the market, but most are likely to underperform.

Non-random walk theory and the best Free Forex Signals
A non-random tour of Wall Street is a collection of essays that provide empirical evidence that valuable information can be gleaned from security prices. Lo and MacKinlay used powerful computers and advanced econometric analysis to test the randomness of security prices. Although this book is a great read, the findings should be of interest to technical analysts and cartographers. In summary, this book documents the presence of predictable components in stock prices.

Just before this book, Andrew Lo wrote an article for the Journal of Finance in 2000: Fundamentals of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation. Harry Mamaysky and Jiang Wang also contributed. The newspaper's initial comments say it all:

“Technical analysis, also known as charts, has been part of financial practice for many decades, but this discipline has not received the same level of academic scrutiny and acceptance as more traditional approaches like fundamental analysis. One of the main obstacles is the highly subjective nature of technical analysis. The presence of geometric shapes on historical price charts is often in the viewer's eyes. In this paper, we propose a systematic and automatic approach to technical pattern recognition using non-parametric kernel regression and apply this method to a large number of EE stocks. USA From 1962 to 1996 to evaluate the effectiveness of technical analysis. When comparing the unconditional empirical distribution of daily stock returns with the conditional distribution conditioned by specific technical indicators, such as head and shoulders or double bottom, we found that during the 31-year sample period, several technical indicators provide incremental information and may have some practical value.
