It should be obvious that such risk-free profit opportunities will be limited in terms of
|
||||
both duration and magnitude. generally speaking, conversion and reverse conversion arbitrage
|
||||
will normally only be feasible for professional arbitrageurs who enjoy much lower transac-
|
||||
tion costs (commissions plus execution costs) than the general public. The activity of these
|
||||
arbitrageurs will tend to keep synthetic futures position prices about in line with actual futures
|
||||
prices.
|
||||
Strategy 16: Synthetic Short Futures (Long put + Short Call)
|
||||
example. Buy an August $1,300 gold futures put at a premium of $108.70/oz ($10,870) and simul-
|
||||
taneously sell an August $1,300 gold futures call at a premium of $9.10/oz ($910). (See Table 35.16
|
||||
and Figure 35.16.)
|
||||
Comment. As follows directly from the discussion of the previous strategy, a synthetic short futures
|
||||
position can be created by combining a long put and a short call with the same expiration date and the same
|
||||
strike price. In this example, the synthetic futures position based upon the $1,300 strike price options
|
||||
is $0.40 higher priced than the underlying futures contract. (Synthetic futures position = $1,300
|
||||
+ $9.10 − $108.70 = $1,200.40.) However, for reasons similar to those discussed in the previous
|
||||
strategy, much of the advantage of an implied synthetic futures position price versus the actual futures
|
||||
price typically disappears once transaction costs and interest income effects are incorporated into the
|
||||
evaluation. An arbitrage employing the synthetic short futures position is called a conversion and was
|
||||
detailed in the previous strategy.
