Protective put versus seasonal debit spread

The archive uses one long-put and short-put construction in two ways. Against a long holding it is described as cover only between the prevailing price and the short put strike. Without that holding it is a vertical debit spread, and a late-spring seasonal idea is the hypothesis that must be specific enough to justify buying the puts.

  • A put or put spread against a long holding is described as covering underlying losses only between the prevailing price and the short put strike.
  • Once the underlying moves through the short strike, the spread no longer fully offsets further decline; more cover is described as requiring extra spreads or wider strikes.
  • Without a long holding, the same long-put and short-put construction is a vertical debit spread whose loss is limited to the debit paid.
  • Protective and speculative uses share that construction. The distinction given is whether a long portfolio is being covered, and a bare opinion that the market will fall is treated as insufficient reason to buy puts.

Shared construction, two uses

The archive treats a long put, or a long put paired with a short put, as one construction that can be used in two ways. Protective use and speculative use share that put or put-spread construction. The distinction given is whether a long portfolio is being covered.

A protective put is a long put held against a long holding so that a defined decline remains a bounded loss before entry and during the position.

Cover only to the short strike

A put or put spread against a long holding is described as covering underlying losses only between the prevailing price and the short put strike.

Once the underlying moves through the short strike, the spread no longer fully offsets further decline in the long holding. More cover is described as requiring extra spreads or wider strikes.

The same strikes without the long holding

The same long-put and short-put construction without a long holding is framed as a vertical debit spread whose loss is limited to the debit paid.

A vertical debit spread is a long option and a short option of the same type and expiration at a nearer strike, so the debit paid is the maximum loss and the width minus that debit is the maximum gain.

Expiration payoff of the SPY 180/170 put debit spread

Without a long stock book this is a prepaid bearish vertical: the 2,810 debit is the most that can be lost above 180, and the 7,190 maximum is realized only at or below the short 170 strike. Profit begins only if SPY is under 177.19 at October expiration, so the 185.64 print on 27 February 2014 already sits on the max-loss shelf. Vertex values are taken from the strategy blotter (1,000 October 180 puts bought at 7.25 against 1,000 October 170 puts sold at 4.44).

Payoff is expiration value from those blotter fills. It is not the live mark of -146.48 in the quote bar, and it ignores the 233 days of remaining theta.

A seasonal thesis, not a bare fall view

A late-spring seasonal timing idea is used as the hypothesis for the debit-spread case. A bare opinion that the market will fall is treated as insufficient reason to buy puts.

Seasonal trading, in the sense used here, is a calendar-timed entry, hold, and exit procedure that can be tested as one rule set rather than a loose story about typical months.

In the worked example, a long 180 put and short 170 put on the same underlying is said to profit only if that underlying is below 177.19 by the stated October expiration.

The four-step procedure

The write-up lists a four-step procedure: a specific reason to buy puts, a risk-acceptable structure, a plan to adjust or exit if the underlying diverges, and study of the structure before live use.
