348 Part Ill: Put Option Strategies In summary, this is a reasonable strategy if one operates it over a period of time long enough to encompass several market cycles. The strategist must be careful not to place a large portion of his trading capital in the strategy, however, since even though the losses are limited, they still represent his entire net investment. A varia­ tion of this strategy, whereby one sells more options than he buys, is described in the next chapter. THE CALENDAR STRADDLE Another strategy that combines calendar spreads on both put and call options can be constructed by selling a near-term straddle and simultaneously purchasing a longer­ term straddle. Since the time value premium of the near-term straddle will decrease more rapidly than that of the longer-term straddle, one could make profits on a lim­ ited investment. This strategy is somewhat inferior to the one described in the pre­ vious section, but it is interesting enough to examine. Example: Suppose that three months before January expiration, the following prices exist: XYZ common: 40 January 40 straddle: 5 April 40 straddle: 7 A calendar spread of the straddles could be established by selling the January 40 straddle and simultaneously buying the April 40 straddle. This would involve a cost of 2 points, or the debit of the transaction, plus commissions. The risk is limited to the amount of this debit up until {he time the near-term straddle expires. That is, even if XYZ moves up in price by a substantial amount or declines in price by a substantial amount, the worst that can happen is that the dif­ ference between the straddle prices shrinks to zero. This could cause one to lose an amount equal to his original debit, plus commissions. This limit on the risk applies only until the near-term options expire. If the strategist decides to buy back the near­ term straddle and continue to hold the longer-term one, his risk then increases by the cost of buying back the near-term straddle. Example: XYZ is at 43 when the January options expire. The January 40 call can now be bought back for 3 points. The put expires worthless; so the whole straddle was closed out for 3 points. The April 40 straddle might be selling for 6 points at that time. If the strategist wants to hold on to the April straddle, in hopes that the stock might experience a large price swing, he is free to do so after buying back the January
