1 Introduction

PURPOSE: we provide a detailed discussion

of the similarities and differences between forward contracts and futures contracts; under frictionless markets and continuous trading, simple arbitrage arguments are invoked to value forward contracts, to relate forward prices and spot prices, and to relate forward prices and futures prices; we also argue that forward prices need not equal futures prices unless default free interest rates are deterministic.

assumptions: frictionless and continous trading

we do not anylyze the effects of these impediments such as margin requirments, transactions fees ,taxes, and institutional

trading restrictions to free trading

An arbitrage valuation method for forward contracts with frictionless market assumptions

Definition of forward contract: a forward

An arbitrage valuation method for forward contracts with frictionless market assumptions

f(s) f (p(s, t*);k(t),t*)

＊ p(s , t ) :the forward price at time s

k(t ) :the exercise price f(s) :the forward contract’s price at time s t: the date the contract is written s: the current time t * :the delivery date

t≤ s ≤t＊

A general forward contract formula

f (p(s, t*);k(t),t*)= {p(s, t*)- k(t)}B(s,t*) (3)

The Derivation process of the formula

t A long position S A short position t＊ Value(long):

k(s) = p(s, t＊)

The combined value at s :

p(t＊, t＊) - p(t,t＊)

Value(short):

k(t)= p(t , t＊)

f{p(s, t ), k(t),t } = {p(s , t＊) - p(t , t＊)}B(s , t＊); k(t)= p(t , t＊)

The term B(s , t＊) is the value at time s of a default-free discount bond that pays one dollar at time t＊

＊

＊

p(s , t＊) - p(t＊, t＊)

The combined value:

p(s, t＊) - p(t , t＊)

Here

B (t* , t* ) = 1

f (p(t*,t*);k(t),t * ) = p(t*,t*)- k(t) (2)

Then ,we add a factor :storage costs Let D(t ,s) be the present value of the known

storage costs associated with holding the underlying asset over [t ,s] . We define

D(t ,t ) = 0

Consider the following portfolio : buy the spot asset to store over [t , t＊] and sell units of the default-free discount bond paying one dollar at

p(t,t)/B(t,t＊)
