According to Burton G Malkiel, the daily changes in the closing price of a stock follow a random walk- that is, these daily events are independent of each other and move upward or downward in random manner and can be approximated by a normal distribution.To test this theory, use internet or newspaper to select three company from NSE/BSE and then do the following: Q-1: Record the daily closing price of these companies for six weeks (30 values) Q-2: Record the daily changes in the closing stock prices of these companies. For each of your six data set, decide whether the data are approximately normally distributed by a) Examining Histogram by) Comparing data characteristics to theoretical properties c) Construct a normal probability plot d) Discuss the result a) through c). What can you say about three stock with respect to daily closing prices and daily changes in closing prices? Which, if any, of the data sets are approximately normally distributed?
