Capital-Asset-Pricing : Based on the capital-asset-pricing model, what is the expected return on the above portfolio?

Suppose you have invested $50,000 in the following four stocks: Security Amount Invested Beta Stock A $10,000 0.7 Stock B 15,000 1.2 Stock C 12000 ...continues

What is the forward price of your contract? b. Suppose both the spot rates unexpectedly shift downward by 1 percent. What is the price of a forward contract otherwise identical to yours?

You enter into a forward contract to buy a 10 year, zero-coupon bond that will be issued in one year. The face value of the bond is $1000, and the 1-year spot interest rates are 4 percent per annum at 9 percent per annum, respectively. Both of these interest rates are expressed as effective annual yields (EAYs). a. What is ...continues

Accounting, face value of bonds sell for

9. How much should a $1,000-face-value bonds sell for, assuming the following conditions: The bond pays a coupon of 11% The coupon payments are paid annually. The required rate of return on similar-risk investments is 9%. The bond matures in 15 years 10. How much should a $1,000-face-val ...continues

Numerical Linear Algebra. Norms.

Find two norms on the space C[0,1] that are not equivalent. Justify your answer. ( Please prove that the example you provide is a norm on the given space and show that the 2 are not equivalent.)

Numerical linear algebra/norms

Based on the parallelogram law, show that the norms ||.||_1 (1-norm) and ||.||_infinity ( infinity or maximum norm) in R^2 are not induced by any inner product. Parallelogram Law: ||u+v||^2 + ||u-v||^2 = 2||u||^2 + 2||v||^2. ||x||_1: = sum i = 1 to n of |x_i| ||x||_infinity := max ( 1 =< i =< n)|x_i|

Numerical Linear Algebra. Neuman Lemma.

Prove the Neuman Lemma: if ||A|| < 1, then I - A is invertible. Here ||.|| is a norm on the space of nxn matrices induced by a norm on R^n or C^n ( C is complex plane). I want a detailed proof. Thanks.
