Ramona Sanjuan is planning to invest $10-million of her own money but she is undecided among the following two alternative portfolios:

• Portfolio 1: Investing $4-million in a North-American Market Index fund “A” and the rest in a European market index fund “B”

• Portfolio 2: Investing $7-million in fund “A” and the rest in fund “B”
  The predicted returns over the next year for fund “A”, fund “B”, and T-bills are as follows:

Given above information, determine:

1 a) The expected return on fund “A” and fund “B”, respectively. [2 points]
1 b) The standard deviation of fund “A” and fund “B”, respectively [2 points] 1 c) The covariance between the returns on fund “A” and fund “B” [2 points] 1 d) The correlation coefficient between both funds [2 points]

For portfolio 1, determine:

2 a) The expected return [2 points]

2 b) The risk of the portfolio (standard deviation). [2 points] 2 c) The reward to variability (RTV) ratio. [2 points]

For portfolio 2, determine

3 a) The expected return [2 points]
3 b) The risk of the portfolio (standard deviation). [2 points]
3 c) The reward to variability (RTV) ratio. [2 points]
4) Which of the two portfolios should Ramona choose? Why? Justify your answer. [2 points]

1.there is an example of a three-year annuity, which the first payment is in year 1, the second payment in year 2, and the third payment is in year 3. However, if the first payment will be paid in the second year, how can I calculate the present value of such annuity.

2.Why the annuity due's result in a higher present value? If you have cash outflow, wouldn't your money be less and the present value shouldn't be decreased?

3.It is said that continuous compounding is the mathematical limit compounding interest can reach. And at that time n reaches infinity, so the formula changed from FV = P*(1+r/n)^(nt) to FV = P*e^(rt). I have no idea how these changes happened and I want to know when and how to use this formula.

4.I don't really understand that when I compound interest if I'm dealing with months or quarters, I have to divide 4 or 12.
Quarterly compounding: FV = 1000(1+(0.05/4))^(4*3)
Monthly compounding: FV = 200(1+(0.05/12))^(12*3)

could you please explain the meaning on why to divide 4 or 12?

Solve x(y^2+U)Ux -y(x^2+U)Uy =(x^2-y^2)U, U(x,-x)=1

Three parallel wires, each carrying a current I (left and right wire carry upward current and middle wire carries downward current....but all wires have the same magnitude current). Four points are identified on the picture as well.   What are the directions of the magnetic fields at the four points, starting with point 1, then 2, etc.

Question

A wire is wrapped around a cardboard tube and carries a steady current in the direction shown (up in front, down in back).   If an observer were inside the tube, near the center, which direction would the observer expect to experience the magnetic field?

Question options:

Question

Two concentric circular loops of wire each carry current I. The smaller loop has a clockwise current, while the larger loop carries a counterclockwise current. Point P is located at the center of both circles. What is the direction of the magnetic field at point P?
