One good way is to do an online survey so you get the results intantly. the downside of online is that not every one knows that there is a survey. Hard copy surveys are also good, but the tend to get lost and cluttered. oh yeah, the more people take the survey, the more accurate it should be
B) did not acquire the instrument in good faith
Answer:
a reduced availability of these badly needed products.
Explanation:
Price control is when the government imposed a price regime that is aimed at protecting the consumer from over pricing by sellers. When price ceilings are imposed there is a maximum price the the seller cannot go above in pricing of products.
In this case if ocal governments imposed price controls that prevented sellers from raising their prices for badly needed products like plywood and generators. It will result in reduced availability of the products to these areas.
Sellers tend to reduce amount supplied, due to scarcity consumers will have to buy at black market prices that are higher.
Answer: ER(P) = ERX(WX) + ERY(WY)
16 = 13(1-WY) + 9(WY)
16 = 13 - 13WY + 9WY
16 = 13 - 4WY
4WY = 13-16
4WY = -3
WY = -3/4
WY = -0.75
WX = 1 - WY
WX = 1 - (-0.75)
WX = 1 + 0.75
WX = 1.75
The amount to be invested in stock Y = -0.75 x $106,000
= -$79,500
The Beta of the portfolio could be calculated using the formula:
BP = BX(WX) + BY(WY)
BP = 1.14(1.75) + 0.84(-0.75)
BP = 1.995 - 0.63
BP = 1.365
Explanation: The expected return of the portfolio is equal to expected return of stock X multiplied by the weight of stock X plus the expected return of stock Y multiplied by weight of security Y. The weight of security Y is -0.75. The weight of security X is equal to 1 - weight of security Y. Thus, the weight of security X is 1.75 since the weight of security Y is negative. The amount to be invested in security Y is -0.75 x $106,000, which is equal to -$79,500
The Beta of the portfolio equals Beta of stock X multiplied by weight of stock X plus the Beta of stock Y multiplied by weight of stock Y. The weights of the two stocks have been obtained earlier. Therefore, the Beta of the portfolio is 1.365.
