You own a portfolio that is 34 percent invested in Stock X, 22 percent invested in Stock Y, and 44 percent invested in Stock Z.
Sonja [21]

Answer:

13.86%

Explanation:

34% was invested into stock X with an expected return of 11%

22% was invested into stock Y with an expected return of 18%

44% was invested into stock Z with an expected return of 14%

The expected return on the portfolio can be calculated using the formula below

Expected return= Sum of ( weight of stock×return of stock)

= (0.34×11%)+(0.22×18%)+(0.44×14%)

= 3.74+3.96+6.16

= 13.86%

Hence the expected return on the portfolio is 13.86%

Diano4ka-milaya [45]

Option D

In the short-run, if there is a surplus in the market for a product, the rationing function of price can be expected to cause:  a decrease in the market price of the product.

<h3><u>Explanation:</u></h3>

When quantity provided surpasses quantity required, a surplus endures.  If the value goes up, the amount of necessitated goes downward. If the price drops, the quantity required raises. Price ceilings limit a price from growing beyond a particular level.

When a price ceiling is fixed under the equilibrium price, the amount required will pass quantity fulfilled, and excess demand or deficits will result. Price floors block a price from dropping below a reliable level. When a price floor is fixed beyond the equilibrium price, the measure supplied will exceed the quantity needed, and excess stock or surpluses will happen.
