Suppose that the value of a stock varies each day from $8.82 to
$21.17 with a uniform distribution. Find the third quartile, i.e.,
75% of all days the stock is below what value? Round your
answer to the nearest cent.
$
Solution :
Given that,
a = 8.82
b = 21.17
PERCENTILE= a + (b - a)p
=8.82+(21.17-8.82)0.75
=15.8775
=16$

a. A share of ARB stock sells for $80 and has a standard deviation of returns equal to 20% per year. The current risk-free rate is 9% and the stock pays two dividends: (1) a $2 dividend just prior to the option's expiration day, which is 91 days from now (i.e., exactly one-quarter of a year), and (2) a $2 dividend 182 days from now (i.e., exactly one-half year). Calculate the Black-Scholes value for a 91-day European-style call option with...
The value of a stock market share may be assumed to vary from day to day according to the following rule: if it is £n one day (n > 0), then the next day with probability p it will be worth £(n + 1) and with probability q-it will be worth E(n Gary owns one share. Today it is worth £10. Gary has decided to sell the share immediately if its value either drops to £6 (in which case he...
