Series 3 — National Commodity Futures Examination Quick Review

How to Use This Quick Review

This independent quick review is for candidates preparing for FINRA’s Series 3 — National Commodity Futures Examination using exam code Series 3.

Use it to quickly reinforce the highest-yield futures, options, hedging, account, order, and regulatory concepts before moving into topic drills, mock exams, and detailed explanations.

A strong Series 3 review plan should include:

1. Concept recall — know the vocabulary and rules.
2. Calculation fluency — practice futures P/L, tick values, hedges, spreads, basis, and option breakevens.
3. Decision recognition — identify whether a customer should buy, sell, hedge, speculate, spread, or use options.
4. Regulatory judgment — recognize improper communications, guarantees, discretionary trading issues, customer fund problems, and prohibited practices.
5. Original practice questions — use a question bank to test whether you can apply the rule under exam-style wording.

Big-Picture Exam Mindset

The Series 3 tests whether you understand:

The Candidate Trap

Many candidates know definitions but miss questions because they fail to identify the position owner’s risk.

Ask:

• Does the customer already own or produce the commodity?
• Does the customer need to buy the commodity later?
• Is the customer worried about prices rising or falling?
• Is the trade a hedge, speculation, spread, or option strategy?
• Is the question asking for profit, loss, effective price, basis, or required action?

Core Futures Concepts

What a Futures Contract Represents

A futures contract is a standardized agreement traded on an exchange to buy or sell an underlying commodity or financial instrument at a specified price for a future delivery or settlement month.

Long vs. Short Futures

Futures P/L Formula

For a long futures position:

\[ \text{Profit or Loss} = (\text{Exit Price} - \text{Entry Price}) \times \text{Contract Size} \times \text{Number of Contracts} \]

For a short futures position:

\[ \text{Profit or Loss} = (\text{Entry Price} - \text{Exit Price}) \times \text{Contract Size} \times \text{Number of Contracts} \]

Tick Value

The tick is the minimum price fluctuation.

\[ \text{Tick Value} = \text{Minimum Tick Size} \times \text{Contract Unit} \]

High-yield trap: if a question gives price movement in points, cents, ticks, basis points, or fractions, convert carefully before multiplying.

Contract Specifications and Quotation Traps

Exam questions usually provide the contract details needed for calculations. Your job is to use them correctly.

Common Quotation Traps

Margin, Settlement, and Leverage

Futures Margin Is Not a Down Payment

Futures margin is a performance bond, not a partial purchase price. The customer is not borrowing the rest of the contract value in the same way as a securities margin account.

Margin Review Example Logic

If a customer is long futures:

• Settlement price rises → account credited.
• Settlement price falls → account debited.

If a customer is short futures:

• Settlement price falls → account credited.
• Settlement price rises → account debited.

Common Margin Mistakes

• Treating futures margin as a loan.
• Forgetting daily settlement.
• Assuming the original margin amount is the maximum possible loss.
• Forgetting that leverage magnifies both gains and losses.
• Ignoring that additional funds may be required quickly.

Hedging Decision Rules

Hedging questions are among the most important Series 3 calculation and judgment questions.

The Core Hedge Rule

Short Hedge

A short hedge protects against a price decline.

Typical short hedgers:

• Farmers with crops to sell later.
• Producers with inventory.
• Merchandisers holding a commodity.
• Portfolio managers protecting equity value.
• Exporters expecting to receive a foreign currency.

Short hedge logic:

1. Sell futures now.
2. Sell the cash commodity later.
3. Buy back futures later.
4. Futures gain helps offset lower cash price if prices fall.

Long Hedge

A long hedge protects against a price increase.

Typical long hedgers:

• Food processors.
• Manufacturers needing raw materials.
• Importers needing foreign currency.
• Portfolio managers planning future equity purchases.

Long hedge logic:

1. Buy futures now.
2. Buy the cash commodity later.
3. Sell futures later.
4. Futures gain helps offset higher cash price if prices rise.

Basis

Basis is one of the highest-yield Series 3 concepts.

\[ \text{Basis} = \text{Cash Price} - \text{Futures Price} \]

Basis Interpretation

Basis and Hedger Results

Effective Price Formulas

For a short hedge:

\[ \text{Effective Selling Price} = \text{Cash Sale Price} + \text{Futures Gain or Loss} \]

For a long hedge:

\[ \text{Effective Purchase Price} = \text{Cash Purchase Price} - \text{Futures Gain or Loss} \]

Basis Trap

Do not assume a hedge creates a perfect fixed price. It reduces price risk but leaves basis risk.

Hedge Ratio and Number of Contracts

When contract size does not match the cash exposure, calculate the number of contracts.

\[ \text{Number of Futures Contracts} = \frac{\text{Cash Market Exposure}}{\text{Futures Contract Size}} \]

For stock index futures:

\[ \text{Number of Contracts} = \frac{\text{Portfolio Value} \times \text{Beta}}{\text{Futures Price} \times \text{Multiplier}} \]

Hedge Ratio Traps

• Round only as appropriate to the question.
• Beta adjusts equity portfolio sensitivity.
• A beta above 1 means the portfolio is more volatile than the index.
• A beta below 1 means the portfolio is less volatile than the index.
• Overhedging can create speculative exposure.

Spreads

A spread is a position with one long leg and one short leg, often designed to profit from the relationship between two prices rather than the outright price direction.

Futures Spread Types

Bull and Bear Futures Spreads

The safest exam approach: identify which leg is long and which leg is short, then calculate each leg’s result.

Spread P/L Method

1. Compute gain/loss on the long leg.
2. Compute gain/loss on the short leg.
3. Net the two.
4. Multiply by contract size and number of spreads.

Common Spread Traps

• Thinking both legs must profit.
• Forgetting one leg is long and the other is short.
• Ignoring whether the spread widened or narrowed.
• Confusing a futures spread with an options spread.
• Forgetting contract size if different commodities are involved.

Futures Pricing, Carry, and Market Structure

Carrying Charge Market

A carrying charge market exists when deferred futures prices are higher than nearby prices, often reflecting storage, insurance, financing, and other carrying costs.

Common label: contango.

Inverted Market

An inverted market exists when nearby futures prices are higher than deferred futures prices.

Common label: backwardation.

Cost of Carry Factors

Cash-and-Carry Arbitrage Logic

If futures are too high relative to cash and carrying costs:

1. Buy the cash commodity.
2. Sell futures.
3. Carry the commodity.
4. Deliver or offset to lock in the relationship, subject to practical constraints.

If futures are too low relative to cash and carrying costs, reverse cash-and-carry logic may apply, where feasible.

Delivery and Cash Settlement

Physical Delivery

For physically delivered contracts:

Cash Settlement

Cash-settled contracts do not result in physical delivery. Instead, final settlement is based on a specified index or final settlement value.

Common cash-settled products include many stock index and financial futures.

Delivery Trap

Most speculators do not intend delivery, but exam questions may test what happens if a position is held too close to delivery or final settlement.

Options on Futures

An option on a futures contract gives the buyer a right, not an obligation, involving the underlying futures contract.

Exercise and Assignment

Option Premium

The buyer pays premium. The writer receives premium.

Intrinsic Value

For a call:

\[ \text{Intrinsic Value} = \max(\text{Futures Price} - \text{Strike Price}, 0) \]

For a put:

\[ \text{Intrinsic Value} = \max(\text{Strike Price} - \text{Futures Price}, 0) \]

Time Value

\[ \text{Time Value} = \text{Premium} - \text{Intrinsic Value} \]

Moneyness

Option Breakevens

The breakeven is the same for buyer and writer, but their profit/loss is opposite.

Option Strategy Review

Protective Strategies

Speculative Strategies

Option Greek Concepts

Option Traps

• A call is not automatically bullish for everyone; the buyer is bullish, the writer is generally neutral/bearish.
• A put buyer wants futures prices down.
• Option buyers have limited risk equal to premium paid.
• Option writers can have substantial risk.
• Exercise of an option on futures creates a futures position.
• Time value declines as expiration approaches, all else equal.
• Higher volatility generally increases option premiums.

Orders and Execution

Order Type Table

Buy/Sell Stop and Limit Rules

Order Trap Examples

• A sell stop below the market does not guarantee sale at the stop price.
• A buy stop above the market can be used to protect a short futures position.
• A stop-limit gives price protection but creates non-execution risk.
• A limit order can miss the market.
• A market order can be filled at a worse price than expected in fast markets.

Market Participants and Account Roles

Commercials, Speculators, and Arbitrageurs

Registration and Business Role Concepts

Know the functional differences among common futures industry roles.

Customer Account Concepts

Customer Funds and Protection

Segregation Concept

Customer funds for futures trading must be kept separate from the firm’s own funds under applicable customer protection rules.

High-yield points:

• Customer funds are not firm operating capital.
• Customer funds should not be used for proprietary purposes.
• Customer segregation protects customers from firm misuse, but it does not eliminate trading losses.
• Foreign futures and options may involve different customer fund treatment than domestic futures.

Margin and Customer Fund Trap

A customer can lose more than the initial margin deposit. Futures leverage can create losses requiring additional funds.

Market Analysis

Fundamental Analysis

Fundamental analysis studies supply and demand.

Technical Analysis

Technical analysis studies price action, volume, and market behavior.

Open Interest Rules

Price, Volume, and Open Interest Interpretation

Do not treat technical indicators as guarantees. They are analytical tools, not certainties.

Interest Rate Futures

Interest rate futures often test the inverse relationship between interest rates and debt instrument prices.

Interest Rate Hedge Rules

Interest Rate Trap

Do not say “rates rise, futures rise” for Treasury-style debt futures. Debt prices generally move inversely to rates.

Currency Futures

Currency futures questions often test importers, exporters, and exchange rate movement.

Currency Trap

Read the quotation carefully. If the contract is quoted in U.S. dollars per unit of foreign currency, a rising futures price means the foreign currency is strengthening against the U.S. dollar.

Stock Index Futures

Stock index futures are used to hedge or adjust equity market exposure.

Beta-Adjusted Hedge

Use beta to adjust for portfolio sensitivity to the index.

\[ \text{Contracts} = \frac{\text{Portfolio Value} \times \text{Beta}}{\text{Index Futures Price} \times \text{Multiplier}} \]

Stock Index Trap

A perfect hedge is unlikely if:

• Portfolio beta is estimated incorrectly.
• Portfolio composition differs from the index.
• Futures and cash prices do not move exactly together.
• The hedge is rounded to whole contracts.

Regulatory and Ethical Review

The Series 3 requires strong recognition of improper conduct and customer protection issues.

Regulatory Structure Concepts

Communications With the Public

Communications should be fair, balanced, and not misleading.

Avoid:

• Guaranteed profit claims.
• Downplaying risk.
• Cherry-picked performance.
• Misleading hypothetical results.
• Omitting material assumptions.
• Implying futures are suitable for everyone.
• Promising that stop orders eliminate loss.
• Using testimonials or performance claims without required context.

Sales Practice Red Flags

Discretionary Accounts

Discretionary trading means someone other than the customer decides key trade terms.

Review points:

• Written authorization is generally required.
• Discretion must be supervised.
• Unauthorized discretion is a major violation.
• Time-and-price discretion may be treated differently from full trading discretion depending on the facts and applicable rules.
• A customer’s verbal instruction does not automatically authorize broad discretionary trading.

Prohibited Trading Practices

Customer Complaints and Supervision

High-yield principles:

• Complaints must be handled according to firm procedures and applicable rules.
• Supervisors must review trading, communications, and discretionary activity.
• Records must be accurate and retained as required.
• A firm cannot ignore red flags in customer accounts.
• Associated persons must not settle complaints privately outside required procedures.

Risk Disclosure Themes

Expect exam questions to test whether a customer has been given a realistic understanding of futures and options risk.

Futures Risk

• Leverage can create large losses quickly.
• Losses can exceed funds deposited.
• Markets can be volatile and illiquid.
• Stop orders may not limit losses to the stop price.
• Spread trading is not risk-free.
• Delivery or liquidation issues may arise near expiration.

Options Risk

Promotional Performance Trap

Past performance, hypothetical results, and selected examples should not be presented as if they guarantee future results.
