Tomorrow’s midterm exam in Finance 4366 consists of 2 sections. The first section is required of all students and consists 4 multiple choice problems 8 points each. The second section is worth 64 points; it consists of 3 problems in which only two are required. At your option, you may complete all three problems, in which case I will count the two highest scoring problems (worth 32 points each). The maximum possible score on this exam is 100 (96 points possible for sections 1 and 2 and 4 points for including your name on the exam booklet :-)). Furthermore, I just posted the formula sheet for Midterm Exam 1, which will be included as part of the exam booklet. I recommend that y’all familiarize yourselves with this document sometime prior to tomorrow’s exam.
I’d like to make an important point about the formulas provided on the formula sheet for the replicating portfolio approach to option pricing. There, I list replicating portfolio values at inception and at expiration. Keep in mind that this approach involves determining a weighting scheme such that one replicates call or put payoffs by appropriately choosing stock exposure (delta) and bond exposure (beta). At this point in the course, we only allow for two possible option payoffs at expiration; thus, there actually are two equations for the replicating portfolio at expiration. These equations reflect the fact that the value of the underlying asset is different in each possible terminal state. However, since she value of the underlying asset is known at the inception of the option, there is only one equation for the replicating portfolio at that point in time.
I just realized that I had forgotten to post this information – better late then never, right?

As promised, I have posted the solutions for the first Finance 4366 midterm exam which was given during the Spring 2018 semester. The link is http://fin4366.garven.com/spring2019/midterm1_spring2018_solutions, and this link is also available at the http://fin4366.garven.com/sample-exams/ page.
Tomorrow’s class meeting (Thursday, 2/14) will be devoted to a review session for Midterm Exam #1. The midterm exam will be given in class next Tuesday, February 19. In order to prepare for tomorrow’s review session, I highly recommend reviewing problem sets 2 – 5 (actually, problem set 5 is due tomorrow! 😊) and midterm 1 from Spring 2018; solutions for problem sets in FIN 4366 are available at http://derivatives.garven.com/category/problem-set-solutions/. After class tomorrow, I will post the solutions for problem set 5 and for midterm 1 from Spring 2018.
I have posted Problem set 4 on the course website. This problem set is based upon the “Properties of Stock Options” reading, and it consists of four problems. It is due at the beginning of class on Tuesday, February 12.
The fourth problem in this problem set references an Excel spreadsheet template called “Derivagem” which you can download from http://fin4366.garven.com/spring2019/DG300.xls. Open DG300.xls up in Excel, and you’ll encounter a dialog box which looks something like this:
Click on “Enable Macros”, and once the spreadsheet is open, select the “Equity_FX_Index_Futures_Options” worksheet. The upper left corner of the spreadsheet is where you input the data for the problem. For this problem, “Underlying Type” is “Equity”, “Option Type” is “Black-Scholes – European”, a $.50 dividend is paid in 6 months, which corresponds to .5 year, the current stock price is $41, volatility is 35%, and the risk-free rate of interest is 6%, the option’s life is 1 year, and the strike or exercise price is $40:
Once you have input these data, select the call button for the call option price and the put button for the put option price. Depending on whether you select “Put” or “Call”, when you click on “Calculate”, the spreadsheet will report back put and call option prices based on the Black-Scholes-Merton (BSM) option pricing formula. For now, this formula may be somewhat of a black box for many (if not most) of you, which is a “problem” we will surely rectify in the not-too-distant future in Finance 4366.
Here’s a two-page synopsis of yesterday’s class discussion of Hull’s “Properties of Stock Options” Chapter:
I have decided to offer the following extra credit opportunity for Finance 4366. You can earn extra credit by attending and reporting Dr. Tom Hazlett’s upcoming talk entitled “5G Wireless and the Quest for Bandwidth: A Property Rights Analysis”. Dr. Hazlett’s talk is scheduled for Thursday, February 7 from 4-5:15 in Foster 240.
If you decide to take advantage of this opportunity, I will use the grade you earn on your report to replace your lowest quiz grade in Finance 4366 (assuming that your grade on the extra credit is higher than your lowest quiz grade). The report should be in the form of a 1-2 page executive summary in which you provide a critical analysis of Dr. Hazlett’s lecture. In order to receive credit, the report must be submitted via email to firstname.lastname@example.org in either Word or PDF format by no later than Monday, February 11 at 5 p.m.
