Q

3 possible scenarios for no arbitrage pricing of a forward contract on an investment ASSET that… + their formulae

A
  1. An investment asset that pays no income
    F0,T = S0(1+rrf)^T
  2. pays fixed known income
    F0,T = (S0-I)(1+rrf)^T
  3. pays fixed known yield
    F0,T = S0(1+rrf-y)^T

Q

2 possible scenarios for no arbitrage pricing of a forward contract on investment COMMODITIES with… + their formulae

A
  1. Investment commodities with fixed known storage costs
    F0,T = (S0+U)(1+rrf)^T
  2. with net convenience yield
    F0,T = S0(1+rrf-NCY)^T

Q

Pricing forwards on foreign currency formula

Currency spot exchange rate formula

A

F0,T(HC/FC) = S0(HC/FC) [(1+rHome)/(1+rForeign)]^T

Spot exchange rate = HC/FC

Q

Arbitrage strategy involving foreign currency

eg. sell forward at t=0, arbitrage profit at t=1

A
  • sell more expensive currency, buy cheaper currency

Portfolio 1 (forward)
t=0, sell forward (no cash flow at time 0)
t=1, collect __

Portfolio 2
t=0,
1. Borrow __
2. Buy __ at spot rate
3. Invest __ at risk-free rate
t=1,
1. Repay __ with interest
2. Collect __ with interest

Q

Arbitrage strategy involving commodities

eg. sell forward at t=0, arbitrage profit at t=1.
Commodity is gold.

A

eg. short sell forward contract (b/c more expensive), long replicating portfolio

Portfolio 1 (forward)
t=0, sell forward
t=1, collect PAYOFF = K - ST

Portfolio 2
t=0,
1. Borrow
2. Buy gold
3. Pay storage
t=1,
1. Repay at EAR
2. Gold position, +ST

Q

3 main uses for derivatives

A
  1. Hedge risk
    - derivatives used to remove/reduce the risks associated w/ their economic activities or investment portfolios
  2. Speculation (making bets)
    - if you don’t actually own the underlying asset. Risky strategy, can either win or lose a lot.
  3. Create arbitrage portfolios
    - replicate payoffs of derivative portfolio

Q

Net convenience yield, NCY, for Commodities (instead of investment assets)

{also taken from 2016 paper}

A

NCY = y - s
= convenience yield - storage cost
= the value of having an inventory - storage cost

Convenience yields can differ seasonally, eg. harvest times, heating season

  • Storage costs: physical commodities cost money to keep hold of
  • Convenience yields: there might be a utility benefit to having a physical store of a commodity rather than a derivative claim to that commodity.

Q

2 pros of Futures

A
  1. NO DEFAULT RISK
    - The contract says once goes below 1000, you need to top up (prevention of default mechanism)
  2. Can get off the contract BEFORE maturity date by using the EXCHANGE
