IE523- Mid-Term Programming Assignment Solved
Instructions
1. If you worked with someone on a specific problem, make sure you tell me about it. If you do not do this and I notice a verbatim reproduction of material, I consider it as plagiarism. There can
be serious consequences to this.
(a) I will randomly pick ≈ 6 students in the class, who will be asked to explain all aspects of their submitted code to me. Do not be disturbed if your name appears in this list – I just need to go through it to ensure the grading is fair.
2. If you picked-up the solution from some source, make sure you mention it. If you do not do this and I notice a verbatim reproduction of material, I consider it as plagiarism. There can be
serious consequences to this.
3. Each submitted document should be personalized. I expect to see
(a) C++ code and header files (if any), the comments in the code should pretty much tell me what you are trying to do
(b) A PDF version of sample-runs that accompanies each submission, have to be uploaded on Compass by the due date.
4. The written In-Class Exam will be held during class hours on 17 October 2018.
I want you to write a comprehensive, readable (i.e. put a lot of comments; have meaningful variable names; etc. etc.) Portfolio Optimization Software Package in C++ assuming you have parallel shifts in the term structure.
Input Specification: The input file to your software will have the following format:
1st-line: #CFs
2nd-line: CF-1’s PV Maturity
3rd-line: CF-2’s PV Maturity
4th-line: CF-3’s PV Maturity
··· ··· ··· ··· ··· ··· ··· ··· ··· ···
kth-line: CF-k’s PV Maturity
(k + 1)th-line:
FV of user’s
due
debt obligation
date
(i.e. k-many Bonds; the 1st number in each row is the PV of the bond, followed by the bond’s cash-flows; not all of them have the same maturity; followed by the FV of user’s debt obligation and the time when its is due).
Output Specification 1: We do not assume a flat term structure, but we assume the term structure changes are parallel (i.e. the yield changes by the same %-age amount for all maturities).
1. Compute the YTM for each cash flow.
2. Compute the duration for each cash flow.
3. Compute the convexity for each cash flow.
Output Specification 2 Assuming no changes in term structure, compute the %-age of the face value of each cash flow you would have to purchase to meet the future debt obligation.
Output Specification 3: Pick the bond-portfolio that will meet this obligation when it is due, and has the largest convexity among all possible portfolio choices. You should pose this as a Linear Programming Problem and use lp solve to find the optimal answer. Your final answer will say that we need to buy λ1% of first cash flow, λ2% of second cash flow, λ3% of third cash flow, etc. No short-selling is permitted (i.e. all your λ’s have to be non-negative).
1. In your write-up, present an explanation of the strategy/method that you used in picking the best portfolio.
2. Make sure your program will handle the case when there is no portfolio that will meet the debt obligation if we are worried about (parallel) movements in the term structure (cf. figure 2).
I also want to see a couple of sample runs (cook-up your own data; or use lesson 4 of my notes).
Partial Credit Information: This should help you decide how your efforts should be spent in the next two weeks.
1. (20 points) Making sure you catch every possible error/infeasibility that might occur in the general setting.
2. (20 points) Soundness of your theoretical arguments for the design-methodology that you adopt for the portfolio design.
3. (60 points) The correct functioning of your code.
A sample screen shot is shown in figure 1.

Figure 2: A sample screen shot of an infeasible set of cashflows.
Figure 3: A sample screen shot for the example that is done in lesson 4. You can compare these results with those in the Brute-Force Excel Spreadsheets provided on Compass with Lesson 4.
