Lagrangian Multipliers

There is a section in the assigned “Optimization” reading due Thursday, January 16 on pp. 74-76 entitled “Lagrangian Multipliers” which (as noted in footnote 9 of that reading) may be skipped without loss of continuity. The primary purpose of this chapter is to re-acquaint students with basic calculus and how to use the calculus to solve so-called optimization problems. Since the course only requires solving unconstrained optimization problems, there’s no need for Lagrangian multipliers.

Besides reading the articles entitled “Optimization” and “How long does it take to double (triple/quadruple/n-tuple) your money?” in preparation for this coming Thursday’s meeting of Finance 4335, make sure you have completed the student information survey, subscribed to the  Wall Street Journal, and subscribed to the course blog (if you haven’t already done so).

Welcome to the Spring 2020 edition of Finance 4335!

Happy new year!  My name is Dr. James R. Garven, and I am your professor for the Spring 2020 edition of the Risk Management course at Baylor University.  Here are a few things to keep in mind as we head into the beginning of the Spring 2020 semester:

1. Finance 4335 will meet on Tuesday and Thursday from 2-3:15 p.m. in Foster 428 (beginning on January 14).

2. The home page for Finance 4335 is at http://fin4335.garven.com, and the course syllabus is at http://fin4335.garven.com/syllabus.pdf. I use Canvas for two purposes only: linking to the course website and posting grades.

3. Course-related documents (e.g., assigned readings, problem sets, sample exams, lecture notes, etc.) are distributed from the course website.

4. The course blog is at http://risk.garven.com and linked from the “Course Blog” button on the home page of the course website. I use the course blog to post important announcements and provide insights linking course topics with the “real” world. I recommend that you regularly follow the course blog via any of the following methods:

a. Via Facebook, by simply “liking” the Finance 4335 Facebook Page (at https://www.facebook.com/finance4335/);
b. Via Twitter, by visiting http://twitter.com/fin4335; and/or
c. Via email; see https://wp.me/p7ESgv-2yJ  for subscription instructions.

5. The Baylor Bookstore lists the required textbook for Finance 4335 (Integrated Risk Management, by Neil A. Doherty) as out-of-stock. However, the book is available from Amazon (https://www.amazon.com/gp/product/0071358617), and assigned book chapters (in PDF format) are available from the course website (see http://fin4335.garven.com/textbook), so this is a manageable “problem”.

6. Try to complete the Finance 4335 Student Information Survey (at http://bit.ly/4335survey) prior to the first day of class on January 14 so I can read up on all of your names, academic backgrounds, interests, and aspirations (similar information about me is available at http://garven.com).  I count the Finance 4335 Student Information Survey as a problem set which receives a grade of 100 (if successfully completed any time between now and the second day of class on January 16), and 0 otherwise.

In closing, I hope you have had a wonderful Christmas break and that you are looking forward to a happy and productive Spring 2020 semester at Baylor University (particularly in Finance 4335)!

Sincerely,

Dr. Garven

On the relationship between the S&P 500 and the CBOE Volatility Index (VIX)

Besides going over the course syllabus during the first day of class on Tuesday, January 14, we will also discuss a particularly important “real world” example of financial risk. Specifically, we will look at the relationship between stock market returns (as indicated by daily percentage changes in the SP500 stock market index) and stock market volatility (as indicated by daily percentage changes in the CBOE Volatility Index (VIX)):

As indicated by this graph from page 21 of the lecture note for the first day of class, daily percentage changes on closing prices for VIX (which is the x-axis variable) and the SP500 (which is the y-axis variable) are strongly negatively correlated. The blue points represent 7,557 daily observations on these two variables, spanning the time period from January 3, 1990 through December 27, 2019. When we fit a regression line through this scatter diagram, we obtain the following equation:

{R_{SP500}} = 0.0594 - 0.1126{R_{VIX}},

where {R_{SP500}} corresponds to the daily return on the SP500 index and {R_{VIX}} corresponds to the daily return on the VIX index. The slope of this line (-0.1126) indicates that on average, daily VIX returns during this time period were inversely related to the contemporaneous daily return on the SP500; i.e., when volatility as measured by VIX went down (up), then the stock market return as indicated by SP500 typically went up (down). Nearly half of the variation in the stock market return during this time period (specifically, 48.91%) can be statistically “explained” by changes in volatility, and the correlation between {R_{SP500}} and {R_{VIX}} comes out to -0.7. While a correlation of -0.7 does not imply that {R_{SP500}} and {R_{VIX}} always move in opposite directions, it does suggest that this will be the case more often than not. Indeed, closing daily returns on {R_{SP500}} and {R_{VIX}} during this period moved inversely 78.44% of the time.

You can see how the relationship between the SP500 and VIX evolves prospectively by entering http://finance.yahoo.com/quotes/^GSPC,^VIX into your web browser’s address field.

Textbook for Finance 4335

The textbook for Finance 4335 is entitled “Integrated Risk Management: Techniques and Strategies for Managing Corporate Risk”. Here’s how the Baylor Bookstore lists this title:

While the Finance 4335 textbook is “out of stock” at the Baylor Bookstore, this book is available for purchase from Amazon.com as well as various other online booksellers. Alternatively, you may also download and print assigned chapters from the course website.

I supplement Doherty’s book with readings from various other sources, as well as readings which I have authored. See http://fin4335.garven.com/readings/ for a date-ordered list of reading assignments. Since the first reading assignment from the textbook isn’t due until Tuesday, January 28, y’all have plenty of time to order the book online, or if you prefer, source textbook readings from the course website.

How to obtain a Wall Street Journal subscription

A subscription to the Wall Street Journal is required for Finance 4335. For online access only, sign up for a “Student Digital Pack” at https://education.wsj.com/search-students. A Student & Digital Pack option (which provides daily home delivery in addition to online access) is available at https://r.wsj.com/PROFxypa.

Throughout the semester, I will often reference specific WSJ articles on the course blog and in class. Finance 4335 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 4335 but also your other courses and careers:

Calculus and Probability & Statistics recommendations…

Since many of the topics covered in Finance 4335 require a basic knowledge and comfort level with algebra, differential calculus, and probability & statistics, the second class meeting during the Spring 2020 semester will include a mathematics tutorial, and the third and fourth class meetings will cover probability & statistics. I know of no better online resource for brushing up on (or learning for the first time) these topics than the Khan Academy.

So here are my suggestions for Khan Academy videos which cover these topics (unless otherwise noted, all sections included in the links which follow are recommended):

Finally, if your algebra skills are generally a bit on the rusty side, I would also recommend checking out the Khan Academy’s review of algebra.
