BOPM for Options on Futures Contracts (p. 3)
Consider a 6-months European Call for one Futures contract on one share of IBM:
▸ K = $50 ▸ r = 6%/year (with c.c. )
▸ Size of the futures contract is for 1 share of IBM
▸ The current futures price ( F0 ) is $50, and in 6 months it will be either $56 or $46
Futures Prices Futures Values Call Values
t= T= t= T= t= T=1
56 (FU) $6
F0P= $50 F0V= 0 C0= ??
46 (FD)
To find the call value set
6 Δ + B e0.06/2 = 6
-4 Δ + B e0.06/2 = ➟ Δ*= 0.6 and B*=$2.33
Thus, at time 0, C0 = Δ F0V +B = 0.6 (0 ) = $2.33
