Risk Management Case Study:Currency Option Overlay presented to CCAD2005 - Québec • Maxime TessierVice President Currency Management 18 August 2005
Parameters of the problem • Three phases of the overlay • Performance conclusions
Parameters of the problem Underlying Manager Profile and Objective • Underlying currency manager chooses long/short forward-based strategies. • Investment horizon is three months, linear and 55% right (ex-ante). • Stop-loss is set at one-third of the expected gain fixed from starting point. • Stop-loss is continuous. • Objectives: improve the return/risk ratio of this strategy with option overlay.
Parameters of the problem Case Study: Bullish Strategy on EUR/NOK
Parameters of the problem “Normal View” versus Manager’s “Actual View” B 45% A A+B=55%
Parameters of the problem Calculating the Actual Expected Payoff: 0,076% In first month, risk of 1% stop is 45%. In second month, it is 14%. In third month, it is 2% Manager is right (55%) Gross expected return 3% P x 3% = [(1-45%)*(1-14%)*(1-2%)] x 3% (1-P) x –1% = 53.6% x –1% .766% -.295% Over three months, the risk of 1% being touched is 87.8%. Manager is wrong (45%) Gross expected return 0% 12.2% x 0% 87.8% x –1% 0.000% -.395% Without a 1% stop, the actual expected payoff would be just over 1%
Three Phases of Overlay Viewing the Manager’s view and historical returns Note: it is assumed that the ex-ante upside distribution for the manager’s view does not exceed the historical distribution (I.e. view distribution is skewed)
Three Phases of Overlay EUR/NOK Historical Return Profile
Three Phases of Overlay EUR/NOK Historical Volatility Profile Note: data based on annualized data using percent returns from end-month to end-month (WMRH data).
Three Phases of Overlay Option Price Graph Note: composite implied volatility quotes (Bloomberg data).
