An average price Asian call on a stock has a strike of 50. The stock price is observed at four quarterly dates, with prices of 48, 52, 56 and 60. The payoff is based on the arithmetic average of these four observations. What is the payoff at maturity?

The payoff is 4. The arithmetic average of the four observed prices is 54, and the average price call pays the average minus the strike of 50, giving 4. Using the final price of 60 would wrongly give 10.

  3. C4
  4. D5

Explanation

Average = (48+52+56+60)/4 = 216/4 = 54. Payoff = max(54-50, 0) = 4. Option 10 uses the final price minus strike (60-50). Option 3 is the wrong-base error of using 53. Option 5 would come from an incorrect average of 55.
