How CC works

The premium reduces your cost basis and adds income, but it caps the upside you already own. The trade makes sense when you are happy to sell the shares at the strike.

Exact option legs

Long 100 shares + sell 1 call

  • SELL 1 × $105.00 call expiring 2026-01-16 at $2.20

Payoff, breakeven and risk

At expiration the position is worth the intrinsic value of each leg. The maximum profit is $1,520.00, the maximum loss is -$8,980.00, and the position breaks even at $89.80.

Worked example

With the underlying at $103.00:

  • Selling the 105 call for 2.20 collects $220 against 100 shares.
  • The effective sale price becomes $107.20 if the stock is called away.
  • Breakeven on the position drops from the $92 cost basis to $89.80.

Strike selection

Sell the strike you would accept for the shares. Further out-of-the-money strikes collect less premium but keep more upside; near strikes collect more and are more likely to be called away.

Expiration selection

Short expirations let you recycle premium but cap gains over a short window; longer expirations collect more but lock the shares to the strike for longer.

Effect of time decay

This structure is positive on theta: net time decay works in its favour.

Effect of implied volatility

It is negative on vega: falling implied volatility helps.

Effect of stock movement

The position suits a moderately bullish or neutral view, and it is tested most when the underlying moves outside the modelled strikes.

Assignment considerations

Assignment risk is high. Short legs can be assigned, especially when they are in the money or before a dividend; long legs have no obligation but can be exercised.

When it works poorly

  • When you expect a sharp rally and do not want to cap your gains.
  • When implied volatility is very low and the premium is thin.
  • Around earnings or news that could gap the stock above the strike.

Common mistakes

  • Selling calls against shares you are not willing to sell, then buying them back at a loss.
  • Chasing the highest premium with a strike far below your cost basis.
  • Forgetting that dividends and early assignment can change the outcome.

Tax caveat

Option outcomes can receive different tax treatment from share trades, and assignment changes the holding period and cost basis. This is general information, not tax advice; confirm your situation with a qualified professional.
