Table 1Yearly annual and semi-annual payment of interest
Year 12
Bond value 1000
Annual coupon rate 2.65%
Current price 965.4
Interest rare
Annual interest 26.5
(Par value-Market price)/Number of years of maturity 2.883333
Annual interest + (Par value-Market price)/Number of years of
maturity 29.38333
(Par value+Market price)/2 982.7
YTM 3%
Semi-annual interest rate 6%
Annual payment of interest is 3% on the bond and if interest is paid on semi annual basis then
in that case interest rate is 6%. There is close connection between yield to maturity and
frequency of interest. If interest is paid semi annually then in that case yield to maturity will
be high. On other hand, if interest is paid on yearly basis then in that case yield to maturity
will be low.

Table 2Portfolio standard deviation and return
Weight of MXX 0.50
Weight of SOX 0.50
STDEV of MXX 0.27
STDEV of SOX 0.40

Correlation 0.629335
Portfolio STDEV 0.300152
Weight of MXX 0.50
Weight of SOX 0.50
Expected return on
MXX 16%
Expected return on
SOX 13%
Portfolio return 15%
It can be seen from the table that portfolio return is 15% and portfolio standard deviation is
0.30. Return is quite high and risk is very low. If investment is solely made on MXX then in
that case return percentage will be 16% and standard deviation will be 0.27 which indicate
that MXX is performing better then portfolio. Return on SOX is 13% and standard deviation
is 0.40. In case of SOX also performance is not much different from the portfolio. Hence, it
can be said that by doing investment in portfolio risk can be controlled but it is not generating
better return then individual stocks and not giving same at low risk relative to SOX and
MXX.

Table 4CAPM of AIR
Tbill rate 0.00%
Rm 16%
Beta AIR 1.444483274
CAPM 22.9%
Return on stock MXX is -0.19% and theoretical return on AIR is 22.9%. It can be said that

Table 5Black-Scholes Option Pricing Model
Current Stock Price $ 182.56
Exercise Price $ 185.00
Risk-Free Interest Rate 1.50%
Expected Life of Option 0.8
Volatility 20.0%
Call Option Value $ 11.41

Call option value is $11.41. In calculation of call option value variables taken into account
are current stock price, exercise price, risk free rate of interest, expected life of option and
volatility. By using Black Scholes model entire calculation is done.
