Costs, Benefits, and Risks

Unit 14 covered what derivatives are. This section covers why an adviser would, or would not, use them with a client: what each position costs, what it offers over holding the underlying asset outright, what can go wrong, and how to match that risk to a client profile.

What Does It Cost to Use a Derivative?

Options (paid by the buyer):

• Premium: the upfront cost of acquiring the right; non-refundable, paid regardless of whether the option is ever exercised
• Time decay (theta): premium erodes as expiration approaches, and decay accelerates in the final weeks; short-dated at-the-money options generally see the fastest time decay, since they carry the most time value to lose
• Commissions: transaction costs for opening and closing positions; can be material for short-dated or low-priced contracts

Example (time decay in action): A trader buys a call for a $3.00 premium with 45 days to expiration. If the stock price does not move at all, that $3.00 is pure time value, since there is no intrinsic value backing it up. With 20 days left, the same option might be worth $1.50, and in the final week it could fall toward $0.30. Decay accelerates as expiration nears rather than eroding at a steady daily rate.

The buyer who paid $3.00 has lost value purely from time passing, with the stock unchanged. The seller who collected that $3.00 premium gains from the same decay: the obligation they are on the hook for is now cheaper to close out, or more likely to expire worthless. Every day that passes without an adverse move in the stock is a day closer to keeping the full premium.

Futures (both buyer and seller post capital):

• Margin (performance bond): good-faith deposit to open the position; not a loan, but capital is tied up and could be earning a return elsewhere (opportunity cost)
• Margin calls / variation margin: daily mark-to-market gains and losses flow through the margin account; when the account falls below the maintenance margin, the trader must deposit variation margin to restore the account to the initial margin level (not just back to maintenance), or the position is liquidated

Forwards:

• No standardized margin: a forward is a private, bilateral contract, so there is no exchange-mandated performance bond or daily mark-to-market; any collateral is whatever the two counterparties separately negotiate
• Negotiation and legal costs: drafting a customized contract carries its own transaction cost

Warrants and rights:

• Purchase price if traded separately on an exchange
• Bundled cost if attached to a bond or preferred stock offering (the sweetener affects the underlying security's price)

Exam Tip: Gotchas

Futures margin is a performance bond, NOT a loan. No interest is charged. This differs from securities margin, where the broker lends money to buy the security.

A margin call requires restoring to the initial margin level, not the maintenance level. The deposit required is called variation margin. A common wrong answer is that the trader only needs to restore back to the maintenance level.

What Do Derivatives Offer an Adviser?

Hedging (the dominant adviser use case):

• Protective put (long stock + long put): downside insurance while preserving unlimited upside
• Covered call (long stock + short call): premium income in exchange for capping upside
• Index puts: hedge a diversified portfolio against systematic (market) risk
• Currency or interest rate forwards: hedge specific institutional exposures

Income generation:

• Covered call writing produces premium income, appropriate for flat-to-slightly-bullish outlooks
• The premium received is the seller's compensation for taking on the obligation to sell the stock at the strike price if the call is exercised; the writer keeps the premium either way, but must deliver shares if assigned

Leverage:

• A small premium controls a large position; returns are amplified relative to the capital deployed
• Index option multiplier (typically $100) means one contract represents 100x the index level in notional exposure

Flexibility:

• Options can profit in rising, falling, or flat markets depending on strategy
• Index options provide broad-market exposure without buying every constituent

What Risks Does Each Position Carry?

Buyer risks (long options):

• Total loss of premium if the option expires worthless (the entire purchase price is at risk)
• Time decay works against the holder every day the option exists
• The trade-off for limited downside is limited participation in the underlying compared to outright ownership: an option holder gets no dividends and no voting rights, since holding the option is not the same as owning the stock until the option is exercised

Writer risks (short options):

• Uncovered (naked) call writer: unlimited theoretical loss since the stock can rise without limit
• Naked put writer: max loss = strike - premium (stock can only fall to $0)
• Covered call writer: opportunity cost; upside is capped at strike + premium received

Exam Tip: Gotchas

• Naked call writing has unlimited risk: the single most dangerous options position.
• Naked put risk is NOT unlimited: the stock can only fall to zero, so max loss = strike minus premium.

Futures and forwards risks:

• Leverage risk: small adverse moves can wipe out the margin deposit and trigger margin calls beyond the initial capital
• Daily mark-to-market (futures): requires liquidity to meet calls; failure leads to position liquidation
• Counterparty risk: minimal for futures (a central clearinghouse guarantees both sides, greatly reducing but not literally eliminating it); significant for forwards (private bilateral contract with no guarantor). Listed options carry the same minimal counterparty risk as futures, since the Options Clearing Corporation (OCC) acts as buyer to every seller and seller to every buyer.
• Illiquidity in forwards: difficult to exit before maturity since there is no organized secondary market

Cross-cutting risks:

• Complexity risk: many strategies have non-intuitive profit and loss profiles
• Liquidity risk: some contracts have wide bid-ask spreads, especially deep-OTM options or long-dated contracts
• Speculation risk: leverage amplifies losses; maximum loss for a speculative buyer is the premium paid, but that loss can occur quickly

Exam Tip: Gotchas

Forwards carry significant counterparty risk; futures and listed options carry only minimal counterparty risk. If the exam asks which derivative has the most counterparty risk, the answer is forwards, since there is no clearinghouse or clearing corporation standing between the two private parties.

How Suitable Are Derivatives for an Advisory Client?

• Derivatives are complex instruments and are not suitable for all clients
• Investment advisers must assess risk tolerance, investment objectives, experience, and time horizon before recommending
• The adviser's fiduciary duty governs the recommendation: even if a derivative is legal for the client to trade, it must still match the client's situation

Suitability spectrum (lowest risk to most aggressive):

1. Protective puts: insurance on existing stock positions
2. Covered call writing: income on existing stock; appropriate for flat-to-slightly-bullish outlooks
3. Long calls and puts: speculation with limited downside (total premium at risk)
4. Speculative futures: amplified gains and losses; repeated margin calls possible
5. Naked call writing: unlimited loss potential; generally unsuitable for most advisory clients

Client profile signals:

• Income-oriented client with existing stock: covered call writing may be appropriate
• Risk-averse client wanting downside protection: protective put may be appropriate
• Aggressive client with high net worth and experience: speculative strategies may be appropriate with full disclosure
• Inexperienced or risk-averse client: derivatives are generally inappropriate

Exam Tip: Gotchas

The Series 65 tests from the investment adviser's perspective. The question is not just "what does this derivative do?" but "is this derivative suitable for THIS client?" Always match the strategy to the client profile.

What Should You Check on Exam Day?

• Match the cost to the instrument: options pay a decaying premium, futures tie up margin capital, and forwards cost negotiation and legal fees instead of standardized margin.
• Know who benefits from time decay: always the seller, and the effect accelerates as expiration nears.
• Keep the max-gain/max-loss table straight, especially that naked call writing is the only unlimited-loss row.
• Restoring a margin call brings the account back to the initial margin level via variation margin, not just to maintenance.
• Counterparty risk is significant for forwards, but only minimal (not eliminated) for futures and listed options, since a clearinghouse or the OCC guarantees both sides.
• Suitability is judged from the adviser's perspective: a legal derivative can still be an unsuitable recommendation for a specific client.
