CAIIB-ABM-MOD-B - Numerical - Time Horizon & Bond Value Volatility with time horizon & Bond Value
Ex.1 If daily volatility of a Security is 2%, how much will be monthly volatility? Solution Monthly volatility = Daily Volatility * ∫30 = 2*∫30 = 2*5.477 = 10.95%
Ex.2 If per annum volatility is 30% and nos. of trading days per annum be 250, how much will be daily volatility? Solution Annual Volatility = Daily Volatility * ∫250 = Daily Volatility * 15.81 30 = Daily Volatility *15.81 Daily volatility = 30/15.81 = 1.90%
Ex.3 If 1 day VaR of a portfolio is Rs. 50000/- with 97% confidence level. In a period of 1 year of 300 trading days, how many times the loss on the portfolio may exceed Rs. 50000/-. Solution 97% confidence level means loss may exceed the given level (50000)on 3 days out of 100. If out of 100 days loss exceeds the given level on days =3 Then out of 300 days, loss exceeds the given level = 3/100*300 =9 days.
Ex.4 A 5 year 5% Bond has a BPV of Rs. 50/-, how much the bond will gain or lose due to increase in the yield of bond by 2 bps Solution Increase in yield will affect the bond adversely and the bond will lose. Since BPV of the bond is Rs. 50/-. Increase in yield by 2 bps will result into loss of value of Bond by 50*2=100.
Ex.5 1 day VaR of a portfolio is Rs. 50000/- with 90% confidence level. In a period of 1 year (250 days) how many times the loss on the portfolio may not exceed Rs.50000/- Ans. 90% confidence level means on 10 days out of 100, the loss will be more than Rs. 50000/-. Out of 250 days, loss will be more than 50000/- on 25 days
Bond Value, Current Yield Bond-1 Bond-2 Face Value 100 100 Annual Coupon 8% 10% Term to Maturity 3 yrs 4 yrs Market Price 80 90 Ex. 1 Find Current Yield of Bond 2 Solution Coupon amount X100 = 10/90*100 = 11.11% Market Value
Ex. 2 Find YTM of Bond 1 & 2 YTM of Bond 1 = 17.07% YTM of Bond 2 = 13.41%
Ex. 3 Find McCauley Duration of Bond 1 2.76 years
Ex. 4 Find Modified Duration of Bond 2 Solution McCauley duration/1+yield =3.46/(1+13.41%) = 3.46/1.1341 = 3.05 yrs.
Ex. 5 What is %age change in price of Bond 2 if YTM increases by 1% Expected %age change in price =Modified Duration x %age change in yield =3.5 x 1 = -3.05% (Decrease in price of bond) =3.5 x 1 = 3.05% (Increase in price of bond)
Ex.6 As an investor, in which bond would you like to invest. Bond 1 (YTM is more)
