Quick question before we start. The formula for tailing a futures hedge involves e^(−rT). Do you multiply by this factor to account for (a) the present value of daily margin calls, or (b) the compounding effect of reinvesting daily gains and losses? If you hesitated or chose (a), you've found the #1 reason candidates get these high-value questions wrong.
Forwards and futures pricing for the FRM exam is governed by the no-arbitrage cost-of-carry model. Hedging calculations require the Minimum Variance Hedge Ratio (MVHR) for imperfect hedges and "tailing the hedge" to adjust the number of futures contracts, accounting for the compounding effect of daily settlement.

Why Is the No-Arbitrage Principle Your Key to Pricing Forwards?
The entire framework for pricing forwards and futures rests on one powerful idea: the absence of arbitrage. A derivative's price must be set at a level that makes it impossible to lock in a risk-free profit. If you internalize this, you can derive the formulas from logic instead of just memorizing them.
This logic is executed through two primary strategies:
- Cash-and-Carry Arbitrage: If the actual futures price (
F_actual) is too high compared to the theoretical price (F_theoretical), you perform a cash-and-carry. You "carry" the asset to delivery. This means you sell the overpriced futures contract today, borrow funds at the risk-free rate to buy the underlying asset in the spot market, and hold it until the contract expires. At expiration, you deliver the asset to settle your futures position and use the proceeds to repay your loan, pocketing a risk-free profit. - Reverse Cash-and-Carry Arbitrage: If the actual futures price is too low, you do the opposite. You buy the underpriced futures contract, short-sell the underlying asset in the spot market, and invest the proceeds at the risk-free rate. At expiration, you accept delivery of the asset via your futures contract and immediately use it to close your short position. The funds you invested have grown, leaving you with a risk-free profit.
The cost-of-carry model is simply the mathematical expression of this no-arbitrage price. It ensures the futures price equals the spot price plus all costs of "carrying" the asset, minus any income received from it.

q) is:
F₀ = S₀ × e^((r − q)T)
Where r is the risk-free rate and T is time to maturity. For a commodity, q would be replaced by the convenience yield, and storage costs would be added to r.How Do Forwards and Futures Actually Differ?
While priced similarly, a forward and a futures contract have critical structural differences that the FRM exam will test. The most significant is the settlement mechanism.
A forward contract is a private agreement between two parties, with all gains and losses settled in a single cash payment at the contract's maturity. This creates significant counterparty credit risk.
A futures contract is a standardized, exchange-traded instrument. Its key feature is being marked-to-market daily. Gains and losses are settled every single day through a margin account. This dramatically reduces counterparty risk but introduces other complexities.
| Feature | Forward Contract | Futures Contract |
|---|---|---|
| Settlement | At maturity only | Daily (marked-to-market) |
| Counterparty Risk | High | Low (mitigated by exchange) |
| Standardization | Customized | Standardized |
| Liquidity | Low | High |
| Regulation | Self-regulated | Regulated by exchange |
This daily settlement process in futures leads to a subtle but important pricing difference from forwards known as convexity bias. Because daily gains can be reinvested and daily losses must be funded, the final outcome is sensitive to interest rate movements. If interest rates are positively correlated with the futures price, futures prices will tend to be slightly higher than forward prices. The opposite is true if they are negatively correlated.

How Do You Calculate the Optimal Hedge for the FRM Exam?
In the real world, you rarely find a futures contract that perfectly matches the asset you need to hedge. This mismatch creates basis risk, the risk that the spot price of your asset and the futures price do not move together perfectly.
When you use a futures contract on a different but related asset (e.g., hedging jet fuel with crude oil futures), it's called a cross-hedge. To determine the optimal number of contracts for such an imperfect hedge, you must use the Minimum Variance Hedge Ratio (MVHR).
The MVHR, or h*, tells you the ideal number of futures contracts to hold to minimize the variance (risk) of your combined position.
h* = ρ × (σ_S ÷ σ_F)
Where:
ρ = Correlation between the spot asset's returns and the futures returns.
σ_S = Standard deviation of the spot asset's returns.
σ_F = Standard deviation of the futures contract's returns.Once you have h*, you can calculate the optimal number of contracts to short for your hedge. For an equity portfolio, you must also incorporate the portfolio's beta.
Worked Example: Applying MVHR and Tailing the Hedge Correctly
Let's walk through a realistic exam problem that combines all these concepts. This is where candidates who only memorize formulas get exposed.
- S&P 500 futures contract price: 5,000
- Contract multiplier: $250
- Daily standard deviation of portfolio returns (σ_S): 1.5%
- Daily standard deviation of futures returns (σ_F): 1.2%
- Correlation between portfolio and futures returns (ρ): 0.90
- Risk-free rate (r): 4% annually
Step 1: Calculate the Minimum Variance Hedge Ratio (MVHR)
First, determine the optimal hedge ratio h* to account for the imperfect correlation and differing volatilities.
h* = ρ × (σ_S ÷ σ_F)
h* = 0.90 × (1.5% ÷ 1.2%) = 0.90 × 1.25
h* = 1.125
Step 2: Calculate the Optimal Number of Contracts (Un-tailed)
Next, calculate the number of contracts needed. A common trap is forgetting to adjust the portfolio value by its beta. You are hedging the systematic risk, which is Portfolio Value × Beta.
- Value of one futures contract = 5,000 × $250 = $1,250,000
- Effective portfolio value to hedge = $50,000,000 × 1.2 = $60,000,000
N = h* × (Value to Hedge ÷ Value of One Futures Contract)
N = 1.125 × ($60,000,000 ÷ $1,250,000)
N = 1.125 × 48
N = 54 contracts
This is the un-tailed hedge. On the exam, 54 would absolutely be a distractor answer choice.
Step 3: Adjust for Tailing the Hedge
Here is the crucial step. Because futures are marked-to-market daily, gains are reinvested and losses are funded. This creates a compounding effect. Tailing the hedge adjusts the initial number of contracts to ensure the hedge's value will grow to match the desired exposure at maturity. We do this by discounting the future hedge back to its present value.
Tailing Factor = e^(−rT)
T = 3 months ÷ 12 months = 0.25 years
r = 0.04
Tailing Factor = e^(−0.04 × 0.25) = e^(−0.01) ≈ 0.99005
N_tailed = N_un-tailed × Tailing Factor
N_tailed = 54 × 0.99005 ≈ 53.46
Since you can't trade fractional contracts, the manager would short 53 or 54 contracts. The exam will test your understanding of the precise calculation.
