32 trees and martingales Substituting the value of E [ X 3 | F2 ] from the table above it is easily checked that this reduces to E [ E [ X 3 | F2 ]| F1 ] = E [ X 3 | F1 ] . 1) ✷ Here is the formal definition. Suppose that X is an F-measurable random variable with E [|X |] < ∞. 4 (Conditional expectation) E [[ X | G] ; A] E [ X | G] dP = A X dP E [X ; A] . A The conditional expectation exists, but is only unique up to the addition of a random variable that is zero with probability one. This technical point will be important in Exercise 17 of Chapter 3.

It is convenient to write V˜i+1 = V˜i+1 − V˜i and S˜i+1 = S˜i+1 − S˜i . Given their values at time iδt, each of V˜i+1 and S˜i+1 can take on one of two possible values that we denote by {V˜i+1 (u), V˜i+1 (d)} and { S˜i+1 (u), S˜i+1 (d)} respectively. We should like to write V˜i+1 = φi+1 S˜i+1 + ki+1 , where φi+1 and ki+1 are both known at time iδt. In other words we seek φi+1 and ki+1 such that V˜i+1 (u) − V˜i = φi+1 S˜i+1 (u) − S˜i + ki+1 , and V˜i+1 (d) − V˜i = φi+1 S˜i+1 (d) − S˜i + ki+1 . Solving this gives φi+1 = V˜i+1 (u) − V˜i+1 (d) S˜i+1 (u) − S˜i+1 (d) and ki+1 = V˜i+1 (u) − V˜i − φi+1 S˜i+1 (u) − S˜i , both of which are known at time iδt.

1. 3 Consider two dates T0 , T1 with T0 < T1 . A forward start option is a contract in which the holder receives at time T0 , at no extra cost, an option with expiry date T1 and strike price equal to ST0 (the asset price at time T0 ). Assume that the stock price evolves according to a two-period binary model, in which the asset price at time T0 is either S0 u or S0 d, and at time T1 is one of S0 u 2 , S0 ud and S0 d 2 with d < min er T0 , er (T1 −T0 ) ≤ max er T0 , er (T1 −T0 ) < u, where r denotes the risk-free interest rate.
