I think MIT is doing a great service to humanity by allowing people to see such lectures online. I will donate. I hope others do too. Together we can make education a right and not a privilege.
Especially considering a conceited self-appraisal half the lecture. The fuck I care about who the teacher is. The best teachers talk about the subject non-stop, not their credentials.
Why are some people saying the video is useless. The lecturer is cool, did his best to simplify key concepts. i don't think they expected him to give a rigorous/detailed lecture. chill - and enjoy!
Super interesting and informative teacher! I am a non-market risk professional at a global investment bank and loved every minute, thanks Ken hope you are well!
Hi, I am a french student majoring in financial markets and I would have loved to have you as my teacher. You look so passionate, I envy your students. Thanks for the video!
I have to say a big THANK YOU to MIT for providing these lectures. Im currently doing a math/physics double major in NewZealand but I really want to become a quant. This has really opened my eyes to financial markets and the math involved. I am honestly at peace with all the mathematics as I understand most of it. For statistics however, I have done some physics labs that make the statistical concepts in this course reminiscent of the physics labs I have done but I dont know it to much detail; so i guess im gonna have to self study statistical theory.
Mit VaR course conducted by a top speicalist from the industry... Just wonderful. Great uni and high class lecturer. Props for opening the course for outsiders like me. 👍 Ty mit and Ty lecturer Ken
All, there is an error on slide 40. The formula for the portfolio variance should be: =MMULT(MMULT(A2:C2,E2:G4),TRANSPOSE(A2:C2)) then ctrl+shift+enter. Despite the small error, spectacular video, thanks for posting MIT! Kenneth Abbott, you are a great teacher, thanks for sharing your knowledge!
@Ken Abbott Haha, totally understand. Would you mind sending me your email? Would really appreciate having a contact like yourself for topics like this. Best!
I know this is late, but this greatly helps me understand the various scenes in Margin Call where they were discussing the potential upcoming losses. Not just that they were about to lose a huge pile of cash, but how they figured out that it was about to happen. Had no real clue or understanding of what VAR numbers meant.
Also FORTRAN & COBOL coder using cards. USAF required that I be able to read blank Hollerith Cards at 1 card per minute, Baudot paper table at 25 characters per minute. Am another of the ancient ones.
@@kennethabbott8248 Mr. Abbott, where can I find related papers/journals from which I can read more about VAR, Portfolio, Options, Derivatives, etc related to finance? I believe that getting a good in-depth know-how of these things would be beneficial in the long run, atleast for me.
very well explained！ though he jumped too fast about the details of how he constructed the mcs. The core is to use the portfolio correlation matrix's sign vector and eign value to transform normal distributed data to be the same distribution as the portfolio correlation. Then we can generate as many as fake data as we want to simulate what's going on in the worst case.
Please: how to do the final transformations in order to obtain the correlated synthetic data! A practical explanation of that would be most useful! Thank you for this video.
Awesome lecture! Lucky MIT kids. I have a master degree in risk management. I have learnt almost all of the stuff, but I enjoyed it a lot! I love how it refreshes my memory and links my knowledge to practical world. And I liked the jokes haha.
Slide 23 - there is something maybe wrong there? Cause if first says that Credit Spread takes recovery into consideration. Then it's said that PV01 = CSPV01 only if recovery = 0. I think this is not the case (if we define credit spread as considering the LGD as well: in this case any 1bs change in both risk-free rate and Credit Spread will result in a same PV01 = CSPV01. Can anyone check this?
Amazing lecture! Thanks MIT Just one thing, what he said at 0:28:45, "the likelihood of a move [in a fat tailed distribution] of 2.33 SD is more than 1%". Isn't it the other way around? It's fewer observations outside of 2.33 SDs in a fat tailed distribution than it is in a normally distributed.
@@kennethabbott8248 Doesn't that depend on how the fat tailed distribution look? The probability for a extremely large loss are indeed higher in a fat tailed distribution. But it can still be more likely for a 2,33 sigma loss in a normal. For example, 2 distributions, one normal and one fat tailed with the same mean and variance. Both have 1000 observations. In the normal it will be approx 10 events outside 2,33 sigma, but in the fat tailed it can in the extreme case be 1. If that observation is far enough out in the tail, like 15-20 sigma, then the distributions can still have the same variance. Thus the probability of a 2,33 sigma loss is smaller in the fat tailed. Or am I missing something?
@@moosecapital8886 Technically, of course, you are correct. The fact that the two cumulative distribution functions cross each other demands that they cross a second time since both of the associated density functions must integrate out to 1.0. In practice, in a diversified portfolio, the VaR at 99% and 95% are always higher for HS than for VCV or MC. (At least I have never seen any instances of an empirical VaR at these levels be less that that implied by the normal.) Ive seen the crossover between 80% and 95%, typically around 90%. My $0.02.
He has a serious problem with Mother Theresa huh? Jokes aside, I find it a really enjoyable lecture and one of the few ones that don't need 1.5x playback. Thanks and best wishes!
At BT, if Risk Mgt hadn’t had the full support of Charlie Sanford, I doubt the group would have grown as much. You need this for genuine risk mgt to thrive.
47:38 that position vector should be read a column vector in order to conduct x'Ex..otherwise if some people read it as a row vector, you can't do x'Ex because (nx1) cannot multiply a (nxn) matrix..
@@kennethabbott8248 Hahaha after 25 years that's pretty damn good!!! I've only been able to make it to 5, and my fiancee dropped my course...(then me...)
I understand the instructor had to complete the lecture in the allocated time however at multiple points I felt it to be quite rushed. I don't know if this is standard at MIT, but I haven't experienced it in such a rushed manner in other math courses. The slides in themselves aren't very descriptive either to go later and learn from them. I believe there's some room for improvement there. I hope you take it as an honest feedback (I am not some troll, wanted to genuinely learn VaR)

wonderful lecture. I can't believe this is available to general community. Thank you so much, MIT!
He might not have a PhD, but he is an amazing lecturer. Natural born teacher.
Thank you. I'd be a lesser teacher if I had a PhD. My value-add proposition is to explain how things are actually done.
It seems to me that he can empower people and has a lot of knowledge. So the PhD is just a title not a necessarily proof of knowledge.
@@kennethabbott8248 well-said!
he actually has more technical knowledge about stats and econ than most of the phds out there.
Best takeaway from the lecture: “Whats the difference between a bond and a bond trader? A bond matures.” 😂😂😂
🥲🤣🤣
