Q 8) The hedge ratio compares the value of a position protected through the use of a hedge with the size of the entire position itself. A hedge ratio may also be a comparison of the value of futures contracts purchased or sold to the value of the cash commodity being hedged.
Now correlation × sd of future price ÷sd of cash price
0.4×14÷26=0.215384 is hedge ratio
For 1000 ounce of gold futures to be sold is 0.215384
For 4000 ounce of gold 4×0.215384 = 0.86154 ct needed to be sold
Q9 perfectly hedge this portfolio we need to sell futures equivalent to Beta times portfolio value. Here is how to go about it!
Value of future cont need to be sold 19000000×1.25= 23750000
Now value of one future cont
1018 ×250=254500
No of future cont 23750000÷254500= 93.3 cont to be sold
Q10. By 20.651 cont
Now to increase the beta upto 1.65
Add up the value (number of shares x share price) of each stock you own and your entire portfolio.
Based on these values, determine how much you have of each stock as a percentage of the overall portfolio.
Multiply those percentage figures by the appropriate beta for each stock. (Thus, if Amazon comprises 25% of your portfolio and has a beta of 1.43, it has a weighted beta of 0.3575.)
Add up the weighted beta figures.
Value of future cont 1084.7*250=271000
