Answer: B. The capital gains yield is positive.
Explanation:
The Capital Gains Yield is a percentage figure that tells how much an investment has increased in price from it's acquisition.
It works by taking the new value and dividing it by the original value.
Using Stacy as an example, the Stock increased by $4 so assuming she bought the stock for even $0.1 then her Capital Yield is,
= 4/0.1
= 40 * 100%
= 4000% which is positive
As long as the stock was sold for more than it was bought, Capital Yield Gain is positive.
