Answer:
E-Mini futures = $2,939.25
Contract Size = 50
Portfolio Value = $10,000,000, Beta 1.5
Target Beta 2, Planning to increase the exposure
Calculation of Number of contracts needed = [Portfolio Size x (Target Beta - Actual beta)] / Contracts Size x Future Price
= (10,000,000 x (2 - 1.5) ] / 50 x 2939.25
= (10,000,000 x 0.5) / 146962.5
= 5,000,000 / 146962.5
= 34.02228459641065
= 34
So, you need to go Long 34 contracts to Increase the exposure.
