What is the Random Walk Theory? Random Walk Theory says that in an Efficient market, the stock price is random because you can’t predict, as all information is already available to everyone and how they will react depends on their financial needs and choices. Definition and meaning Random walk theory claims that it is impossible to predict which way prices will go in the world of investments. Shares and some other financial assets follow a ** random walk. In other words, it is not possible to know whether the next price movement will be up or down, or how steeply that increase or decline might be. Random walk, in probability theory, a process for determining the probable location of a point subject to random motions, given the probabilities (the same at each step) of moving some distance in some direction. Random walks are an example of Markov processes, in which future behaviour is independent of past history.

The Random Walk Theory or Random Walk Hypothesis is a financial theory that states the prices of securities in a stock market are random and not influenced by past events. It suggests the price movement of the stocks cannot be predicted on the basis of its past movements or trend. A Little More on the Random Walk 2019-06-05 · Home ACM Journals ACM Transactions on Graphics Vol. 38, No. 3 Volume Path Guiding Based on Zero-Variance Random Walk Theory research-article Volume Path Guiding Based on Zero-Variance Random Walk Theory The random walk theory asserts that stock returns can’t be reliably predicted, and stock movements are just like the ‘steps of a drunk man’, which no one can foretell. This theory is based on the assumptions that the prices of securities in the market moves at random and the price of one security is completely independent of the prices of the all the other securities.

I don't agree with the random walk theory because anything that involves human behavior can be traced back to cause and effect. Random walk theory was

The random­walk theory of Brownian motion had an enormous impact, because it gave strong evidence for discrete particles (“atoms”) at a time when most scientists still believed that matter was a continuum. According to the Random Walk Theory stock price changes happen in a so-called random walk.

The Random Walk Hypothesis is a theory about the behaviour of security prices which argues that they are well described by random walks, specifically sub-martingale stochastic processes. The Random Walk Hypothesis predates the Efficient Market Hypothesis by 70-years but is actually a consequent and not a precedent of it. The Random Walk Theory .
