Research paper a random walk

Introduction A random walk is a mathematical object, known as a stochastic or random process, that describes a path that consists of a succession of random steps on some mathematical space such as the integers. Other examples include the path traced by a molecule as it travels in a liquid or a gas, the search path of a foraging animal, the price of a fluctuating stock and the financial status of a gambler can all be approximated by random walk models, even though they may not be truly random in reality. As illustrated by those examples, random walks have applications to many scientific fields including ecology, psychology, computer science, physics, chemistry, biology as well as economics. Random walks explain the observed behaviors of many processes in these fields, and thus serve as a fundamental model for the recorded stochastic activity. As a more mathematical application, the value of pi can be approximated by the usage of random walk in agent-based modelling environment.

What Is the Random Walk Hypothesis?

Image source: Getty Images. Many theorists examine the behavior of stock prices, and the random walk hypothesis attempts to explain why stocks move the way they do. The random walk hypothesis states that stock market prices change in a random manner, and therefore, you can't predict what price movements will occur in advance. The theory argues that each change is independent of previous changes, and so the trends that many investors see in stock charts aren't meaningful.

The random walk hypothesis is a financial theory stating that stock market prices evolve according to a random walk so price changes are random and thus cannot be predicted.

Malkiel , an economics professor at Princeton University and writer of A Random Walk Down Wall Street , performed a test where his students were given a hypothetical stock that was initially worth fifty dollars.
