+Orapter 4: Other Call Buying Strategies 123 
+THE REVERSE HEDGE (SIMULATED STRADDLE) 
+There is another strategy involving the purchase of long calls against the short sale of 
+stock. In this strategy, one purchases calls on more shares than he has sold short. The 
+strategist can profit if the underlying stock rises far enough or falls far enough dur­
+ing the life of the calls. This strategy is generally referred to as a reverse hedge or sim­
+ulated straddle. On stocks for which listed puts are traded, this strategy is outmoded; 
+the same results can be better achieved by buying a straddle (a call and a put). 
+Hence, the name "simulated straddle" is applied to the reverse hedge strategy. 
+This strategy has limited loss potential, usually amounting to a moderate per­
+centage of the initial investment, and theoretically unlimited profit potential. When 
+properly selected (selection criteria are described in great detail in Chapter 36, 
+which deals with volatility trading), the percentage of success can be quite high in 
+straddle or synthetic straddle buying. These features make this an attractive strategy, 
+especially when call premiums are low in comparison to the volatility of underlying 
+stock. 
+Example: XYZ is at 40 and an investor believes that the stock has the potential to 
+move by a relatively large distance, but he is not sure of the direction the stock will 
+take. This investor could short XYZ at 40 and buy 2 XYZ July 40 calls at 3 each to set 
+up a reverse hedge. If XYZ moves up by a large distance, he will incur a loss on his 
+short stock, but the fact that he owns two calls means that the call profits will outdis­
+tance the stock loss. If, on the other hand, XYZ drops far enough, the short sale prof­
+it will be larger than the loss on the calls, which is limited to 6 points. Table 4-2 and 
+Figure 4-2 show the possible outcomes for various stock prices at July expiration. If 
+XYZ falls, the stock profits on the short sale will accumulate, but the loss on the two 
+calls is limited to $600 (3 points each) so that, below 34, the reverse hedge can make 
+ever-increasing profits. To the upside, even though the short sale is incurring losses, 
+the call profits grow faster because there are two long calls. For example, at 60 at 
+expiration, there will be a 20-point ($2,000) loss on the short stock, but each XYZ July 
+40 call will be worth 20 points with the stock at 60. Thus, the two calls are worth 
+$4,000, representing a profit of $3,400 over the initial cost of $600 for the calls. 
+Table 4-2 and Figure 4-2 illustrate another important point: The maximum loss 
+would occur if the stock were exactly at the striking price at expiration of the calls. This 
+maximum loss would occur if XYZ were at 40 at expiration and would amount to $600. 
+In actual practice, since the short seller must pay out any dividends paid by the under­
+lying stock, the risk in this strategy is increased by the amount of such dividends.
