: efficient markets hypothesis, asset price behaviour
(eng): We will interested in the Student's t-distribution since it is fairly simple to implement in empirical applications. We test the random walk hypothesis and then consider an alternative to random walk - the ARIMA model for stock prices. The behavior of volatility of returns over time is studied the GARCH-t model which also allows to us to learn more about the distribution properties of stock returns.
