Answer:
d. Buy 30 contracts.
Explanation:
Correlation between jet fuel and crude oil = 0.9
Standard deviation of spot price = $2 Jet fuel
Standard deviation of futures prices = $3 Crude oil
Minimum variance hedge ratio (h) = Correlation * Standard deviation of spot price / Standard deviation of futures prices
Minimum variance hedge ratio (h) = 0.9 * 2/3
Minimum variance hedge ratio (h) = 0.6
Size of position being hedged = 50000
Size of one futures contracts = 1000
Number of contracts to be used for hedging = Minimum variance hedge ratio * Size of position being hedged / Size of one futures contracts
Number of contracts to be used for hedging = 0.6 * 50000 / 1000
Number of contracts to be used for hedging = 30
=>> 30 contracts = Go long = Buy
