Answer:short 140 contracts
Explanation: Using the formulae
Number of Contracts (Company's position )=( Desired Beta of the portfolio - beta of the portfolio) x Portfolio of stocks) / ( Future Value )
Future Value = Index futures price x Multiplier
=2000 x 250
=$500,000
Putting the values, we have that
Company position =(0.5 -1.2) x $100 million) / $500,000
Company position=-0.7 x $100 million/500,000
Company position=-$70,000,000/500,000
Number of contracts (Company position)=-140 contract
A negative sign means that the contract is going short.
Therefore,
A total of 140 contracts by the company should be short.
