Covered-call versus diagonal housing after a single-name drawdown
The same short-call income idea is housed two ways after roughly a 90 percent decline from 2000 highs, with cash prices near yearly lows and option volatility near yearly highs. A covered-call sits on shares. A diagonal-call-spread sits on a longer-dated in-the-money call. The comparison is remaining debit, leftover upside after the front month expires, and the path when the stock goes nowhere.
- A covered-call buys the shares and sells a call so collected premium lowers net debit and the expiration breakeven versus holding the stock alone.
- The same bullish-to-neutral view can sit in a diagonal-call-spread that uses a longer-dated in-the-money call as a synthetic-share-substitute.
- The case study states worst-case outlay of 850 on the diagonal against 3800 on the stock-plus-call book, which still treats the remaining debit as capital that can be lost to a zero stock price.
- Front-month-decay can still help the diagonal if the stock sits still for a month or two, and leftover upside remains on the long call after the near-term short expires.
A post-drawdown setting
The reader’s setup placed the income idea after roughly a 90 percent decline from 2000 highs, with cash prices near yearly lows and option volatility near yearly highs.
The covered-call housing
A covered-call book is built by buying the underlying shares and selling calls against them. The collected premium is used for cost-basis-reduction. It lowers the net debit and the expiration breakeven relative to holding the stock alone.
The construction is presented for a bullish-to-neutral outlook that expects only a slow rise. The short call is kept inside 45 days so that time decay is meant to leave that option worthless.
In the worked example the stock trades at 40, 100 shares are purchased, and a December 40 call is sold for two points. That leaves a 3800 net debit after a 200 premium credit against a 4000 stock outlay. The remaining 3800 debit is still treated as capital that can be lost down to a zero stock price, even after the premium credit.
The diagonal-call-spread housing
The alternative houses the same view in a diagonal-call-spread. A longer-dated in-the-money long call is financed in part by a shorter-dated out-of-the-money short call. The illustration is a July 30 call with nine months against a December 40 call with two months, while the stock is at 40. The long call is the synthetic-share-substitute in that book.
The same case study states worst-case outlay on that diagonal as 850, compared with 3800 on the stock-plus-call book.
Stillness, leftover upside, and the two paths
Because the front-month short option is said to shed time value faster than the longer-dated long option, front-month-decay can still let the spread gain if the stock sits still for a month or two. Leftover upside remains on the long call after the near-term short expires.
On an advance the long call gains and the short call loses. On a decline the short call gains and the long call is described as losing mainly its time value.
How the payoff sketches are labeled
The covered-call payoff sketch labels a 2-point premium, a 38 breakeven, and a 40 strike. The comparison sketch labels a 30 long strike, a 38.50 breakeven, and a 40 short strike. Both diagrams are noted as excluding commissions and fees and as not to scale.
