Long put versus vertical debit spread on a Treasury ETF

A bond-etf-proxy for the Treasury view

The archive presented a 20-year Treasury bond ETF as a bond-etf-proxy. A bond-etf-proxy is a long-maturity Treasury exchange-traded fund used as an options underlying so an equity-options process can express a fixed-income view without using futures. The fund was treated as an options-accessible proxy that tracks Treasury market moves.

In the last six months of 2013, the source context described Treasuries falling about 20% while interest rates rose, after policymakers began pulling back on bond purchases. From October 2013 the long-bond ETF was described as forming a widening cone of higher highs and lower lows, with both the 2013 lows and the recent highs expected to be tested.

Editorial reading: that cone supplies the first gate. A rate-policy thesis is not yet a structure. It becomes one only after a target price and a holding window are written down.

The price-and-time-gate

A directional option structure was considered only after a bearish price outlook near 100 was set for the ETF. The price-and-time-gate is the requirement to specify both a target price and an expiration window before choosing among directional option structures.

The archive then used May options with 100 days to expiration, so the same target and expiration window applied to both structures that followed.

Long put against the same target

The long-put case bought May 106 puts with 100 days to expiration for 287 per contract. A long-put is a single-leg purchase that pays premium for the right to sell the underlying at a stated strike before expiration. Breakeven is the strike minus the debit, and leftover time value can decay even if the directional view is later correct.

This case needed the ETF at or below 103.13 by expiration to break even.

Vertical debit spread against the same target

The vertical-debit-spread bought that May 106 put and sold the May 100 put. A vertical-debit-spread is a same-expiration put spread that buys a higher strike and sells a lower strike for a net debit, limiting loss to that debit and capping gain at the strike width minus the debit.

The short-leg credit lowered the net debit to 217 and capped reward at 383 because of the short-strike obligation at or below 100. An option-spread is a multi-leg options structure that pairs a long option with a short option so the credit from the short leg changes net debit, defined risk, and payoff relative to a single-leg trade.

Relative to the standalone long put, the option-spread case reduced net debit and defined risk while also capping the payoff if the ETF reached 100 by the May expiration.

Compare first, then watch for an early exit

The comparison procedure required a price-and-time outlook first, then a risk-reward comparison of long-put and option-spread structures, then monitoring for possible exits before expiration.

That last step is the early-exit-monitor: review of an open options position before expiration, because the underlying can reach or fail the thesis while time premium is still changing.

Editorial note: TradersWeek treats debit, breakeven, and the short-strike cap as the comparable signals from the second gate. The archive does not rank the two structures.
