Perhaps a “trigger” warning is in order concerning next Tuesday’s meeting of Finance 4366. Since we’ll be covering the topic of Ito’s Lemma, it will be a bit on the “mathy” side. We will introduce Ito’s Lemma and use it to accomplish (among other things) the following tasks: 1) derive the parameters of the probability distribution for continuously compounded rates of return, and 2) determine the stochastic process for forward contracts. Our class meeting tomorrow will begin with a quiz based upon the assigned readings, which include Hull’s textbook chapter entitled “Wiener Processes and Ito’s Lemma” and my teaching notes entitled “Applying Ito’s Lemma to determine the parameters of the probability distribution for the continuously compounded rate of return” and “Geometric Brownian Motion Simulations“.

# Discrete time to continuous time…

As we segue from discrete-time to continuous time pricing models in Finance 4366, you will surely find this topic to be quite challenging. But it is essential, since a basic understanding of the continuous time framework is, as Hull puts it, “central to the pricing of derivatives”. As you read the readings assigned for Tuesday, March 20 (consisting of Hull’s textbook chapter entitled “Wiener Processes and Ito’s Lemma” and my teaching notes entitled “Applying Ito’s Lemma to determine the parameters of the probability distribution for the continuously compounded rate of return” and “Geometric Brownian Motion Simulations“), keep the following exhortation by Hull in mind (this appears as the third paragraph on the first page of the textbook chapter assigned for next Tuesday):

“Many people feel that continuous-time stochastic processes are so complicated that they should be left entirely to ‘‘rocket scientists.’’ This is not so. The biggest hurdle to understanding these processes is the notation. Here we present a step-by-step approach aimed at getting the reader over this hurdle. We also explain an important result known as Ito’s lemma that is central to the pricing of derivatives.”

# Next Tuesday’s reading assignment for Finance 4366

Here’s the list of assigned readings for next Tuesday’s class meeting:

- Hull Chapter 13 (“Binomial Trees”)
- Binomial Option Pricing Model (single-period)
- Multiple Period Binomial Option Framework
- Dynamic Delta Hedging Numerical Example (calls and puts)
- Dynamic Replicating Portfolio Numerical Example (calls and puts)
- Convergence of the Cox-Ross-Rubinstein (CRR) Binomial Option and Black-Scholes-Merton (BSM) Option Pricing Formulas

The two most important readings for next Tuesday’s Finance 4366 quiz and class meeting are Hull’s “Binomial Trees” chapter and my teaching note entitled “Binomial Option Pricing Model (single-period)”. Tuesday’s class meeting will be primarily devoted to covering the latter reading in particular, although the other readings are also quite important for the next few Finance 4366 class meetings.

# The solutions for Problem Set 2…

… are available at http://fin4366.garven.com/spring2018/ps2solutions.pdf…

# Problem Set 2 helpful hints

Problem Set 2 is now available from the course website at http://fin4366.garven.com/spring2018/ps2.pdf; its due date is Thursday, January 25.

Problem Set 2 consists of two problems. The first problem requires calculating expected value, standard deviation, and correlation, and using this information as inputs into determining expected return and standard deviation for 2-asset portfolios. We covered these concepts during last Thursday’s statistics tutorial; also see pp. 10-20 of the http://fin4366.garven.com/spring2018/lecture3.pdf lecture note. The second problem involves using the standard normal probability distribution to calculate probabilities of earning various levels of return by investing in risky securities and portfolios. We will devote next Tuesday’s class meeting to this and related topics.

# Problem Set 1 hint…

Problem Set 1 is due at the beginning of class on Tuesday, January 16. Here is a hint for solving the 4th question on problem set 1.

The objective is to determine how big a hospital must be so that the *cost per patient-day* is minimized. We are not interested in minimizing total cost; if this were the case, there would be no hospital because marginal costs are positive, which implies that total cost is positively related to the number of patient-days.

The cost equation *C* = 4,700,000 + 0.00013*X*^{2} tells you the total cost as a function of the number of patient-days. This is why you are asked in part “a” of the 4th question to derive a formula for the relationship between cost per patient-day and the number of patient days. Once you have that equation, then that is what you minimize, and you’ll be able to answer the question concerning optimal hospital size.

# How to know whether you are on track with Finance 4366 assignments

At any given point in time during the upcoming semester, you can ensure that you are on track with Finance 4366 assignments by monitoring due dates which are published on the course website. See http://fin4366.garven.com/readings/ for due dates pertaining to reading assignments, and http://fin4366.garven.com/problem-sets/ for due dates pertaining to problem sets. Also keep in mind that short quizzes will be administered in class on each of the dates indicated for *required* readings. As a case in point, since the required readings entitled “Optimization” and ” How long does it take to double (triple/quadruple/n-tuple) your money?” are listed for Thursday, January 11, this means that a quiz based upon these readings will be given in class on that day.

Important assignments due on the second class meeting of Finance 4366 (scheduled for Thursday, January 11) include: 1) filling out and emailing the student information form as a file attachment to options@garven.com, 2) subscribing to the *Wall Street Journal*, and 3) subscribing to the course blog. A completed Student information form is graded as a problem set and receives 100 points; if you don’t turn in a Student information form, then you will receive a 0 for this “problem set”. Furthermore, tasks 2 and 3 listed above count toward your class participation grade in Finance 4366.

# Instructions for subscribing to the Options, Futures and Other Derivatives Course Blog

A course blog has been established for Finance 4366 at the address http://derivatives.garven.com; it is also linked from the “Course Blog” button located on the course website.

# How to obtain a Spring 2018 Wall Street Journal subscription

A subscription to the *Wall Street Journal* is required for Finance 4366. In order to subscribe to the *Wall Street Journal* (*WSJ*) for the Spring 2018 semester, go to http://r.wsj.net/j73NM. Your *WSJ *subscription includes access to print, online, tablet and mobile editions, and only costs $1 for a 15 week subscription. At your option, you may choose to receive both the digital and paper versions of *WSJ *or only the *WSJ* digital version.

Throughout the semester, I will often reference specific *WSJ* articles in class and on the course blog. Finance 4366 topics (as well as topics in many of your other business school courses) come to life in the world outside the Baylor bubble when you read make a habit of reading the *WSJ* on a regular basis. Furthermore, if you expect to interview for jobs or internships anytime soon, reading the *WSJ* will give you a leg up on the competition, since you will be better informed and have more compelling ideas and insights to share with recruiters.

In closing, the following (2 minute) video provides a helpful introduction to the *WSJ*, providing time-saving tips to help you get the most from *WSJ* and succeed not only in Finance 4366, but also your other courses and careers:
