Discussion

The put-call window another way to offset the premium associated with buying a put for downside price protection.

It retains the advantage of options in setting a price floor (at purchased put strike price less the premium, less the basis) while allowing for you to take advantage of higher cash prices -- but only up to the strike price of the sold call. If futures rose above the latter, the sold call becomes a liability (see pink cells). The effect of this causes your purchased put value to"level off ".

The LDP works on top of the put option in providing increasing (offsetting) income as prices fall below the low 50s.

Notes:

  1. Local price is assumed to differ from futures by a constant basis. In reality, this differential is subject to possible "Basis risk" variations.
  2. Premiums paid (less received) for bought (or sold) options.
  3. These values are net of commissions. These values assume only intrinsic value for purchased options, which is realistic when the option is close to expiration, or when exercising into a futures position.
  4. For illustrative purposes only, future LDP value is represented as a fixed 14-cents below the A-Index, which is assumed to be a fixed 7-cents above futures.In reality, the A-index can vary widely in relation to futures,and also vary to a lesser amount from the AWP.

The negative values in the call option column illustrate the risks of selling options. It exposes you to the risk of assuming a short futures position in a rising market.
