Covered Call

Description

Holding the underlying while selling a call against it, trading away upside above the strike for immediate premium income.

Setup

  1. Hold (or buy) one unit of the underlying.
  2. Sell one call option, typically out of the money, against that position.

Context

The default income strategy for a long-term holder who is neutral-to-mildly-bullish and willing to give up any gain above the strike.

Risk Profile

Loss is the same shape as owning the underlying outright, reduced by the premium collected; bounded only by the underlying reaching zero. Gain is capped at the strike plus premium collected.

Pros

  • Generates income on an existing holding.
  • Premium cushions a modest decline.
  • Simple to understand and manage.

Cons

  • Caps participation in a strong rally.
  • Still carries the underlying's downside risk, less the premium.
  • Above the strike, the short call's loss offsets every further gain on the holding.

Effect of Time

Time decay works in your favor on the short call, adding to the position's return each day.

Effect of Volatility

Rising implied volatility increases the premium collected up front, but once the position is open it marks the short call up and the position down, and it raises the odds of the call finishing in the money.

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.

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.

Each leg: what it nets there per contract (fill price with the fee folded in), then the fill price, fee, IV and the size quoted at that price.

This structure holds the underlying itself: its row shows each venue's forward for the expiry, which isn't a price anyone fills at, so it's never marked best or split across venues -- and every total includes it, so the totals differ mostly by each venue's basis.

Pro Per-leg prices and the best venue for each leg are BOSS Pro. See what Pro includes

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.

Market Context

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.
