[answerhappygod]

Price changes of two gold-mining stocks have shown strong
positive correlation. Their historical relationship is:
Average percentage change in A = 0.001 + 0.73(percentage change
in B)
Changes in B explain 60% of the variation of the changes in A
(R2 = 0.6).
A) Suppose you own $112,000 of A. How much of B should you
sell to minimize the risk of your net position?
Amount of B to sell: _______
B) What is the hedge ratio? (Round your answer
to 2 decimal places.)
Here is the historical relationship between stock A and gold
prices:
Average percentage change in A = −0.002 + 1.36(percentage change
in gold price)
c-1. If R2 =
0.48, can you lower the risk of your net position by hedging with
gold (or gold futures) rather than with stock B?
Yes or no?
c-2. Will this provide as good of a hedge
as the sale of stock B?
Yes or no?
