The daily changes in the closing price of stock follow a random walk. That is, these daily events are independent of each other and move upward or downward in a random matter and can be approximated by a normal distribution. Let's test this theory. Use either a newspaper, or the Internet to select one company traded on the NYSE. Record the daily closing stock price of your company for the six past consecutive weeks (so that you have 30 values)....

Let Xn is a simple random walk (p = 1/2) on {0, 1, · · · , 100} with absorbing boundaries. Suppose X0 = 50. Let T = min{j : Xj = 0 or N}. Let Fn denote the information contained in X1, · · · , Xn. (1) Verify that Xn is a martingale. (2) Find P(XT = 100). (3) Let Mn = X2 n − n. Verify that Mn is also a martingale. (4) It is known that...
