Short Put (Naked Put)

Description

Selling a put option uncovered to collect premium, betting the underlying stays above the strike through expiry.

Setup

  1. Sell one put option, typically out of the money.
  2. Keep enough margin set aside to absorb the loss if the underlying falls well below the strike -- crypto options settle in cash, so the loss is paid out, not delivered as the underlying.

Context

A common income play: the seller keeps the premium if the underlying stays above the strike, and otherwise pays the cash difference at settlement -- economically similar to having bought the underlying at the strike minus the premium, though nothing is actually delivered.

Risk Profile

Maximum gain is the premium collected. Loss grows as the underlying falls below the strike, bounded only by the underlying reaching zero -- treated as effectively uncapped for position-sizing purposes.

Pros

  • Collects premium immediately.
  • The loss on a decline is equivalent to buying the underlying at the strike minus the premium, below where it traded when the trade was opened.
  • Profits from time decay.

Cons

  • Large loss possible on a sharp decline.
  • Ties up meaningful margin or cash.
  • Underperforms simply buying the underlying in a strong rally.

Effect of Time

Time decay favors the seller; the position gains value every day the underlying stays above the strike.

Effect of Volatility

Rising implied volatility hurts the position by inflating the value of the short option.

Net cost, breakevens, the payoff chart and the scenario table are after costs: every leg filled by crossing the spread, estimated fees included -- the same numbers the Scanner ranks by.

Estimated Cost to Assemble

An estimate of what entering this structure right now would really cost: filling every leg by crossing the spread (the ask when buying, the bid when selling) instead of at the mid-price, plus an estimated exchange fee. Real fees and fills can differ from this estimate.

Compare venues

These exact contracts -- same strikes, expiries and ratios -- on every venue BOSS tracks for this currency, at execution: what selling (bid) or buying (ask) each leg there comes to, after that venue's own fee. Green marks the best venue for each leg and for the whole structure.

For comparing prices, not a recommendation: quotes move by the second, size is only what's shown at the top of the book, fees are each venue's published estimate, and the venues settle against different indexes and margin separately.

Volatility Smile?

Implied volatility across strikes at this expiry; the marked lines are this structure's strikes. Buying on the high part of the curve pays up for volatility; selling there collects it.

Payoff & Greeks vs. Underlying Price

The Greeks curves are a Black-Scholes model using each leg's current implied volatility, holding time to expiry fixed -- not live exchange data at every price, which only exists at the current price (dashed line).

Payoff at Expiration

After costs At mid price

This structure's value and profit/loss at expiration, at a handful of specific prices: every leg's strike, every breakeven, the current spot, and the chart's own range.
