543 OPTION TrAdINg STrATegIeS strategies. One critical point that must be emphasized regarding option spreads is that these strategies are normally subject to a major disadvantage: the transaction costs (commissions plus cumulative bid/asked spreads) for these trades are relatively large compared to the profit poten- tial. This consideration means that the option spread trader must be right a large percentage of the time if he is to come out ahead of the game. The importance of this point cannot be overem - phasized. In short, as a generalization, other option strategies will usually offer better trading opportunities. Multiunit Strategies The profit/loss profile can also be used to analyze multiple-unit option strategies. In fact, multiple- unit option positions may often provide the more appropriate strategy for purposes of comparison. For example, as previously detailed, a long futures position is more volatile than a long or short call position. In fact, for small price changes, each $1 change in a futures price will only result in approxi- mately a $0.50 change in the call price (the delta value for an at-the-money call is approximately equal to 0.5). As a result, in considering the alternatives of buying futures and buying calls, it probably makes more sense to compare the long futures position to two long calls (see Table 35.22) as opposed to one long call. Figure 35.22 compares the strategies of long futures versus long two calls, which at the time of initiation are approximately equivalent in terms of delta values. Note this comparison indicates that the long futures position is preferable if prices change only moderately, but that the long two-call position will gain more if prices rise sharply, and lose less if prices decline sharply. In contrast, the comparison between long futures and a long one-call position would indicate that futures provide the better strategy in the event of a price advance of any magnitude (see Figure 35.3d). For most purposes, the comparison employing two long calls will be more meaningful because it comes much closer to matching the risk level implicit in the long futures position. tabLe 35.22 profit/Loss Calculations: Long two at-the-Money Calls (1) (2) (3) (4) (5) Futures price at expiration ($/oz) premium of august $1,200 Call ($/oz) $ amount of total premium paid Value of 2 Calls at expiration profit/Loss on position [(4) − (3)] 1,000 38.8 $7,760 $0 –$7,760 1,050 38.8 $7,760 $0 –$7,760 1,100 38.8 $7,760 $0 –$7,760 1,150 38.8 $7,760 $0 –$7,760 1,200 38.8 $7,760 $0 –$7,760 1,250 38.8 $7,760 $10,000 $2,240 1,300 38.8 $7,760 $20,000 $12,240 1,350 38.8 $7,760 $30,000 $22,240 1,400 38.8 $7,760 $40,000 $32,240
