The covered-call income strategy after a 12% fall

Tom, 68, has a $500,000 portfolio of 10 NZX-listed shares and $30,000 cash. He needs $35,000 a year and is worried about volatility. An adviser proposes writing three-month covered calls on 60% of his portfolio, generating about $18,000 premium, with strikes 5% above current prices. Tom's largest holding is 22% in one stock. He says he understands options because he 'traded warrants in the 1980s'. The market falls 12% in month one; the calls expire worthless but the portfolio falls $60,000. Tom asks why he did not benefit from the premium and wants to double the strategy. He also asks whether the adviser's firm, which is paid per options trade, can 'just handle it' without more paperwork.

1. Was the covered-call strategy suitable? Explain the payoff with the numbers.

The strategy is not a volatility cure. The premium is $18,000 on about $300,000 of notional, or 6% annualised on the covered portion, but only 3.6% of the $500,000 portfolio. A covered call caps upside above the strike and provides only the premium as downside cushion. When the market fell 12%, the shares lost about $60,000; the $18,000 premium offset only 30% of that loss, leaving a net loss of about $42,000 before costs. If the shares had risen above the strike, the calls could be assigned and Tom would miss the upside. His need for $35,000 a year is not reliably met by option premiums. He has 22% in one stock and only 10 holdings, so the portfolio is not well diversified. His claimed warrant experience from the 1980s is not evidence of current understanding. A covered-call overlay could be suitable only on a small, diversified portion, with a clear explanation of capped upside and limited downside protection.

2. What should the adviser do after the fall, and what disclosure and records are needed?

Read the worked answer

Do not double the strategy to recover the loss. Review Tom's income need, liquidity, risk capacity, and the concentration in the 22% holding. Explain that the calls expired worthless, so the premium was retained, but the shares still fell; the premium is not insurance. Consider a smaller overlay, a cash buffer, a diversified income portfolio, and a review of the 10-stock concentration. Disclose the options risk, assignment risk, fees and per-trade remuneration, and the conflict created by the firm being paid per options trade. Record the original rationale, the client's understanding, the review after the fall, the recommendation not to double, and any client instruction to proceed. If he insists, document the advice against doubling and escalate if necessary.

3. What ethical and professional issues arise?

Read the worked answer

The adviser must act in Tom's best interests and not promote trading to generate commissions or recover losses. The per-trade remuneration is a conflict that must be disclosed and managed, not used to justify 'just handling it'. Competence is also an issue: recommending an options overlay requires current knowledge of option payoffs and assignment, not reliance on the client's outdated warrants experience. Tom is an older client with a fixed income need, so vulnerability and capacity should be considered. The firm cannot bypass paperwork; the advice, disclosure, client authorization, and review must be documented. If Tom insists on doubling, the adviser may decline to implement, escalate internally, or require a documented acknowledgment that the advice was against it. The ethical answer is to reduce concentration and match income to a sustainable withdrawal plan, not to sell more options.
