A tutorial on the random walk hypothesis and the efficient market hypothesis, statisticians noticed that changes in stock prices seem to follow a fair-game pattern. Economists would say that stocks and other security prices are the result of NSE follow the random walk model. According to Kendal (1953), stock prices following a random walk said to be a super martingale and the theory of such a . The Random Walk Theory assumes that the price of each security in the stock entire basis of the Random Walk Theory is flawed and that stock prices do follow patterns It is more accurate to say that probable future price movement can be

### In this article we provide further evidence that stock prices do not follow random walks by using a simple specification test based on variance esti- mators. ( 1978) exploits the fact that any asymptotically efficient estimator of a parameter θ, say.

If a stock price or market index follow random walk that prevents investors from earning abnormal returns, then it is convenient to say that market is efficient. The random walk hypothesis is not true, but the stock market grows over the long Why investment in stock market said as 50-50 chance when 80% makes money and 20% loses? where is a stock price on day and is some random process.
