4. 4 Case Study: Bullish Strategy on EUR/NOK Parameters of the problem

5. 5 “Normal View” versus Manager’s “Actual View” Parameters of the problem A+B=55% 45%A B

6. 6 Calculating the Actual Expected Payoff: 0,076% Parameters of the problem Manager is right (55%) Gross expected return 3% Manager is wrong (45%) Gross expected return 0% In first month, risk of 1% stop is 45%. In second month, it is 14%. In third month, it is 2% Over three months, the risk of 1% being touched is 87.8%. 12.2% x 0% 87.8% x –1% P x 3% = [(1-45%)*(1-14%)*(1-2%)] x 3% (1-P) x –1% = 53.6% x –1%.766% -.295% 0.000% -.395% Without a 1% stop, the actual expected payoff would be just over 1%
