Q

Simple Forward Pricing Model

A

F(T) = S for all maturities, T
where,
F(T)= current forward price of a contract expiring at time T
S = spot price
For the above to hold true, following assumptions:
- no transaction costs
- risk free rate zero
- underlying assets can be borrowed at zero
- no div yield, convenience yield, storage costs
- underlying asset can be easily obtained

Q

Cash and Carry Arbitrage Strategy

A

At initiation of strategy:
- sell forward contract at F(T)
- borrow cash at risk free, for term of contract, T
- use borrowed funds to buy underlying asset
At contract expiration:
- deliver underlying asset, receive forward price F(T)
- repay interest and principal on the loan

Reverse Cash and Carry Arbitrage Strategy

A

At initiation of strategy:
- buy forward contract at F(T)
- sell underlying asset short at current spot, S
- lend cash received from short at risk free, r
At contract expiration:
- collect loan proceeds, plus interest
- use collect loan proceeds to take delivery of asset at the forward price and cover the short- sale commitment

Q

Financial Forward Pricing Relationships

A
  1. F(T) >S when r>d, resulting in an upward sloping forward curve (i.e. contango); slightly convex
  2. F(T) < S when r <d, resulting in a downward sloping curve (i.e.) a backwardation market; slightly concave

Q

Explanation of Why Forward Prices are Reduced when

r < d

A
  • dividends and coupons cause the value of financial assets to decrease on the day of the distribution. Forward contracts with maturities after the distribution date must reflect the decline in value.
  • Forward contracts only account for the present value of the market price at time T, not the PV of dividends or coupon rates, therefore the forward contract price must be less than the spot.

Q

Forward Pricing Relationship with Convenience Yield

A

F(T) = S x e^[(r+c-d-y) x T]
where:
F(T) = price of forward contract
S = spot price of the underlying asset
e = transcendental number used to calculate, ~2.718
r = risk free rate
c= storage costs
d= continuously compounded dividend or coupon rate
y = convenience yield
T = time to maturity of the forward contract

26
Q

Perfectly Elastic Supply

A

mean that at any level of market demand for an asset (e.g., currencies) can instantly by supplied without limit or price impact.

27
Q

Inelastic Supply

A

means that a change in supply to meet market demand requires large price changes or that supply quantities react slowly to price changes.

28
Q

Key Points Regarding Term Structure of Forward Prices

A
  1. The slope and share of the term structure are driven by differences in the cost of carry.
  2. The slope and shape of the term structure are not related to returns earn on forward contracts.
29
Q

Normal Backwardation

A
  • Refers to a price pattern where the forward price is below the expected future spot price and converges to that price from below over time.
  • thus, long forward contract is expected to earn positive return with no investment, and a short contract is expected to incur a loss.
30
Q

Normal Contango

A
  • Refers to a price pattern where the forward price is above the expected future spot price and converges to that price from above over time.
  • thus, a short forward contract is expected to earn positive return with no investment, and a long forward contract is expected to incur a loss.
31
Q

Possible Forward Market Term Structure Based on Future Expected Values

A

Backwardation- current forward price is less than the current spot price
Normal Backwardation - current forward price is less than the expected future spot price
Contango- current forward price is greater than the current spot price
Normal contango - current forward price is grater than the expected future spot price

32
Q

Hedgers_ Normal Backwardation

A

Hedgers will tend to hold more short contracts than long contracts

33
Q

Hedgers_Normal Contango

A

Hedgers are net long forward contracts rather than net short

34
Q

Futures and Forwards as Beta Drivers

A

Investors who use futures as beta drivers are attempting to gain risk and return exposure of the underlying asset while minimizing the costs

35
Q

Futures and Forwards as Alpha Drivers

A

Investors who use futures as alpha drivers look for violations of the law of one price in the futures market and engage in the appropriate arbitrage transactions.

36
Q

Law of One Price

A

States that two assets with identical payoffs must have the same price.

37
Q

Ex-Ante Alpha Strategy and Term Structure

A

Ex-ante alpha strategies attempt to profit speculation on the changes in the shape of the forward term structure, a belief based on the assumption that the term structure is informationally inefficient (i.e. pricing relationships incorrectly incorporate current information).
-Strategy: purchase underpriced forward contracts and sell overpriced forward contracts.

38
Q

Basis in Terms of Forward Contract

A
  • difference between the spot price and the price of the forward contract.

Basis = S - F(T)
where:
S= spot price of the underlying asset
F(T) = price of the forward contract

39
Q

Calendar Spread

A

Ex-ante alpha strategy that combines a long forward position and a short forward position on the same underlying asset but with different expiration dates.
- implicit bet on the shape of the forward term structure and an attempt to earn profits from the relative mispricing between related forward or futures contracts.

40
Q

Calendar Spread Equation

A

Calendar Spread = F(T + t) - F(T)
where:
F(T) = price of a forward contract that expires at time T
F(T + t) = price of the forward contract that expires at T+t
t = amount of time between expiration of contracts

41
Q

Reasons Commodity Prices Should Have Low Correlation to Prices of Stocks and Bonds

A
  1. Supply and Demand: commodities don’t have cash flows to discount, but are driven by supple and demand interactions.
  2. Correlation with Inflation: inflation and changes in the inflation rate are positively correlated to commodity prices.
  3. Short Term vs. Long Term Expectations: commodities reflect current economic conditions
  4. Capital Costs vs. Raw Material Costs: significant increase in the cost of raw materials will negatively effect the value of stocks and bonds.
42
Q

Inflation

A

Occurs when the value of a currency decreases in relation to a representative basket of goods and services.

43
Q

Commodities as Protection again Inflation Risk

A
  1. Commodity prices are a factor in inflation measures and are, therefore, positively correlated with inflation.
  2. Commodity prices represent the value of consumption. The real value of consumption is independent of inflation rates.
44
Q

Commodity Alpha Return Enhancement

A
  • believe commodities are mispriced based on forcasted prices derived through fundamental and technical analysis.
  • goal of strategy: to gain commodity exposure and hold the position long enough to profit from the anticipated price correction.
45
Q

Equilibrium Beta Return Enhancement

A

Commodities do NOT enhance returns in equilibrium markets.

46
Q

Disequilibrium Beta Return Enhancement

A
  • Investors often do not hold commodities according to their market weights, thus causing a disequilibrium.
  • Commodities in disequilibrium provide greater return per unit of beta risk than other beta exposures.
47
Q

Physical Commodities

A

Physical commodity ownership is an inefficient method of obtaining commodity exposure unless the investor has a high convenience yield or a competitive storage advantage.

48
Q

Commodity Related Equity Investments

A

Pure play investments such as Freeport-McMoRan for copper exposure, has commodity beta in addition to market beta resulting from equity market exposure.
**Many reason that a pure play may not give the same exposure as commodities.

49
Q

Commodity Exchange Traded Funds

A

Low cost opportunities for retail investors to gain commodity exposure.

  • physical: not directly exposed to equity market or futures market risk.
  • futures: exposed to basis risk
  • equities: exposed to equity market and commodity market risk
50
Q

Commodity Exchange Traded Notes (ETNs)

A

Similar to commodity ETFs, but represent a claim to a debt security with cash flows linked to commodity prices.
- exposed to credit risk of the issuing investment or commercial bank.

51
Q

Commodity Linked Notes (CLNs)

A
  • combine a standard interest paying debt instrument with either a commodity futures contract or an option on commodity prices.
  • contains both commodity risk and default risk of the issuer
    Several Advantages:
  • investor does not have to worry about rolling futures to maintain long term exposure.
  • CLN effectively a bond, can be a way to avoid restrictions
  • tracking error issues responsibility of the note issuer.
52
Q

Basis Risk

A

uncertainty in economic outcomes resulting from changes in the spot price/futures price relationship

53
Q

Reasons Return to Commodity Futures Contracts can differ from Spot Returns

A
  1. Cost of carry implies by the basis differs from the cost of carry for the spot.
  2. Basis changes
    Futures contracts with different maturities:
  3. Calendar spread changes
  4. Cost to roll over the long term exposure changes over time.
54
Q

Return on a Fully Collateralized Futures Position

A
  1. Spot Return: reflects changes in the spot price of a commodity
  2. Collateral Yield: interest earned on the risk free asset
  3. Excess Return: changes in futures prices
55
Q

Roll Yield

A
  • return that results from changes in the basis of a futures contract
    Reasons:
    1. passage of time: closer to maturity, futures prices and basis converge
    2. Changes in cost of carry
    Positive Roll Yield: backwardated market
    Negative Roll Yield: contango market
56
Q

Roll Yield on Financial Assets

A

Assuming constant spot prices and term structure, the roll yield on a futures contract for a financial asset with high dividend yield will be positive, while the roll yield on a futures contract for a financial asset with a low dividend yield will be negative.

57
Q

Roll Return Fallacies

A
  1. Roll return is directly attributable to closing and opening positions: Roll return occurs over the contract holding period, and is the difference between the futures price when the contract is opened and the futures price when it is closed less the change in spot price over holding period.
  2. Backwardated markets always generate positive roll return: cost of carry and term structure are not always static.
  3. Positive roll return always generate alpha: futures contracts on financial assets not related to roll return
58
Q

Commodity Futures Index_Use by Managers

A
  1. Benchmark for return attribution and performance analysis
  2. Tool to execute tactical investment strategies on the performance of commodities.
  3. Tool to execute passive investment strategies designed to diversify portfolio risk.
59
