Derivative Characteristics

Quick Answer

Derivatives cost a premium (options) or margin (futures). The adviser's main use is hedging: a protective put insures a long stock position while keeping upside, and a covered call earns premium income but caps upside. Time decay always favors the seller. Naked call writing carries unlimited risk; naked put risk is limited.

The One-Liners That Win Points

  • Premium is the buyer's upfront, non-refundable cost; it is paid whether or not the option is ever exercised.
  • Option premium = intrinsic value + time value; time decay (theta) erodes the premium as expiration approaches, and out-of-the-money options lose value fastest near expiration.
  • Time decay always works against the buyer; the seller always benefits from time passing.
  • Protective put (long stock + long put): downside insurance that preserves unlimited upside.
  • Covered call (long stock + short call): premium income in exchange for capping the upside; appropriate for a flat-to-slightly-bullish outlook.
  • Index puts hedge a diversified portfolio against systematic (market) risk.
  • Futures margin is a performance bond, NOT a loan; no interest is charged.
  • A margin call requires restoring to the initial margin level (via variation margin), not just back to maintenance.
  • Forwards carry counterparty risk; futures do not (the clearinghouse eliminates it).
  • Legality is not suitability: the adviser's fiduciary duty governs every recommendation.

  • Covered call writer upside is capped at strike + premium received.
  • Naked put writer max loss = strike - premium (the stock can only fall to $0).
  • Naked call writer loss is unlimited since the stock can rise without limit.
  • Long option max loss = the full premium paid if it expires worthless.
  • Index option multiplier is typically $100, so one contract represents 100x the index level in notional exposure.

Top Gotchas

  • Protective put vs covered call: the put preserves unlimited upside (it is insurance); the covered call caps upside (it is income). Do not swap them.
  • Naked call writing has unlimited risk (the single most dangerous options position); naked put risk is NOT unlimited because the stock can only fall to zero, so max loss = strike minus premium.
  • A margin call restores to the initial margin level, not maintenance; the deposit is called variation margin.
  • Counterparty risk question: the answer is forwards, never futures.
  • The Series 65 tests from the investment adviser's perspective: the question is not "what does this derivative do?" but "is it suitable for THIS client?" Match the strategy to risk tolerance, objectives, experience, and time horizon.
  • Suitability spectrum, lowest risk to most aggressive: protective puts → covered calls → long calls/puts → speculative futures → naked call writing (generally unsuitable for most advisory clients).

One-Breath Recap

Derivatives cost a premium (options) or margin, a performance bond, for futures. Option premium is intrinsic value plus time value, and time decay always favors the seller. The two adviser hedges are the protective put (long stock plus long put, insurance that keeps unlimited upside) and the covered call (long stock plus short call, income that caps upside at strike plus premium). Long options risk only the premium paid; naked call writing is unlimited loss while naked put loss is capped at strike minus premium. Forwards carry counterparty risk, futures do not, and every recommendation must match the client under the adviser's fiduciary duty.
