"I can calculate the motions of heavenly bodies, but not the madness of people" this gotta be one of the hardest quotes.
Specifically because "motion" actually occurs in ones own material mind only.
And apparently referencing his investment in slavers... Madness of people indeed.

I've never fully grasped how options worked until now, I swear other people go out of their way to make it appear more complicated than it really is.
They do, because they teach you to use them badly so they can exploit when you mess up.
They make it complicated in order to obfuscate truth - you sell and buy things you do not own. Imagine you selling car that is not yours. You would land in jail. But rich and powerful, belonging to certain ethnic group, get bailed out if they screw things up.
too much@@Elemblue2
that's because generally the people that try to teach it, don't grasp it themselves, they just regurgitate.
Its gambling
I love that his answer about whether this helps or not is basically "when things are good it's fine, but when things go bad it makes things much worse". Which...yeah.
Literally what my time series analysis professor says every class
And the biggest question is: what makes things go bad?? And the answer, as it was in the 2008 subprime crisis, is always: the ultra-financialization of markets, paradigmatically showed in the derivatives market
It's not 'avoiding' risk. Someone has to take the risk. And that's the rest of us. Just another way the managerial classes avoid the consequences of their mis-management of the real economy. Not to mention the cumulative transaction costs of high frequency trading.
And it makes things worse for the rest of us. None of them miss meals. The equation tells them how not to. So the techno nerds want to eat their economy. How smart.

It's so fascinating to see the dots being connected from finance to math to a physics breakthrough, science is beautiful

Beauty is subjective.
Maths is not.
Unfortunately, elegant maths is used for some horrific things.

It's worth mentioning that Merton and Scholes, who were champions of the efficient market hypothesis, were part of the board of directors of a hedge fund called Long-Term Capital, which ironically sought to exploit market inefficiencies to make money. The fund ended up collapsing less than 4 years later and receiving a huge bailout.
In the years before, Ed Thorp's fund was making record profits until it was dismantled by the US gov.
Source: Fortune's Formula, very interesting read
came here to say this- LTCM[sic] is my go-to example of the difference between theory and practice.. also, didnt buffett make a giant bet explicitly against black-scholes? a huge long term short put position on the s&p? feel like if he had taken a bath on that it would have made the news.
@@theupsonThe thing about buffet is that he evaluated sticks in a value perspective (what is it worth) which means with a lot of work he will be right and can take positions on a few stocks, whereas black-sholes will be right most of the time for every single stock. So you can beat black-sholes but only reliably by finding value discrepancies in a stock
@@noahbarnett3121 Usually these actors have full Buffet style insider trading options students of commerce dont.
@@theupson Buffett won LTCM lost.
@@noahbarnett3121what is sticks? Where did you learn stock terms? I need to know them.
Unless I missed it, they didn't mention LTCM (Long Term Capital Management). It was a multi-billion dollar investment firm founded in 1994 by two Nobel laureates using the Black-Scholles model -- and it went bankrupt in 1998.
Hopefully part 2 and the discussion of bailouts on these equations
yea because markets are also psychological driven and behave irrational at times. So it just doesnt work long time. I recommend the book "when genius failed" on the LTCM story.
You are correct. Their equations worked in theory not in practice.
Exactly, human is too chaotic, compared to particles movement, more like a random jump instead of random walk.
Market crash is one of the proof that modern portofolio theory is deadly wrong for an extreme event.
Jon Corzine, instrumental in LTCM's bailout, went on to do the exact same thing LTCM did with MF Global. They never learn.
A young economist and an old economist are walking down the street, and the young economist says, "Look! A $20 bill!". The old economist says, "Nonsense. If there were a $20 bill just laying on the ground, someone would have picked it up already."
I guess it only applies to spherical $20 bills in a vacuum.
The up and coming economist replies, "Nah. It's chump change."
When I was a kid looking for my first car (before the internet existed) I’d circle the newspaper ad and show my Dad. He would usually say “Ring and see if it’s sold yet. If it’s a good car at a good price, someone will have already bought it.”
@@farmergiles1065yeah nah that guy is an idiot.
this is the best comment in the comment section
I'll have to remember that one
In case Derek or anyone on his team reads this, $100 in the medallion fund does not compound yearly at 66%. It yields 66% per year. The size of the medallion fund is limited by the size of the options market. If the fund grows too large, their edge experiences diminishing returns. By this fundamental limitation of their strategy, the fund only scales with the efficacy of their edge and the rest is liquidated for employees and original shareholders. If it was truly compoundable, then the fund wouldn't be closed and an efficient market would infinitely allocate to it until itintroduced price distortions that arbitrage the edge. The initial statement about $100 becoming billions in decades is not true.
I mean, obviously... It was just a way to visualize how much a 66% return yearly is compared to the usual ~8% or whatever it is
I gather it's not literally true in terms of the expected gain, but remains generally true that earnings will be high?
@@Luminaria999 Obviously? I would have never thought that
Actually Medallion doesn’t trade options, so their capacity is limited by the number of transactions they’re able to perform daily (millions).
@@Luminaria999 He literally just explained how the money doesn't compound like that. While, the 8% (10%) you are talking about does describe a compounding effect. There is no comparison to make between the two because they don't mean the same thing.
you have such a gift to explain these things. Your video on Fourier transformation helped me immensely in my PhD dissertation actually (i still had to find "legit" sources cause a veritasium video doesn't count, but I understood it better from you than from any "proper" papers). Please never stop making these, you explain complicated things so well
Thank you for a lovely video. Not only have you explained a complex topic easily but also made it enjoyable.
The style of this video is brilliant. It reminds me of a film where there are multiple plot lines and these seemingly unrelated subplots satisfyingly come together at the end.

As a kid who failed math two times before graduating, it's still very interesting

There are plenty you just don't understand anything that's even an inch above the layman's terms. Videos like this just exacerbate the problem by making people think they learned something when in reality it oversimplified so much stuff that it's borderline wrong.
@@shivanshu6204you definitely think you're smarter than you actually are
@@towfik2947 r/iamverysmart
@@shivanshu6204 How do you come to knowledge of this kind of information in the first place? You learn the basics, in oversimplified terms, and graduate to more advanced understandings of concepts. Going to university and getting formal education is one way to do this. However, that’s inaccessible for people who might be past that stage in life or are focused on another major but have interests in this subject. And there certainly are other channels that bring to light information from these subjects, but in much too complicated terms for a beginner to understand, which hurts the field’s credibility in the public’s eyes in being understandable. However, this channel has been able to bring the basic concepts of these subjects in simple and understandable terms, something everyone can gain value from. Yes, whilst some who are inexperienced might make false conclusions from this info, in general, the video is accomplishing its goal of bringing this information to the public in understandable but accurate description. It is certainly accurate and well researched, and if there have been errors or misconceptions in a video of this channel, other channels and the educated public in the field have brought to light such errors (like in his video on electricity). The purpose is not to give people to most precise information, but it is to spark a curiosity in finding more precise information, and this information is not oversimplified at all, it is simply not all the information and explanation, which is what the person themselves must find on their own.
The conclusion here is “yes”: you do think you are smarter than you actually are, this conclusion being derived from the fact that you fail to understand the purpose of this channel and its videos.

Yea, and add this with the fact that the market through Uniform Comemercial Code is set us so banks actually have a claim over your "owned" stocs in a crisis. Lehman Brothers became case law. Search for "The Great Taking".
"It's stable during good times and unstable during bad times" seems like the exact opposite of what people need. Bad times are when you need stability, when things are going well, risk is less of an issue.
These are just both sides of the same medal.
My experience is more with PID loop control which can use derivative control as well ( thus the D).
In general during good times, it can be used as a way to react to change and reduce problems. (trending towards zero)
However if a sufficiently large change occurs, the derivative can "flip" and exacerbate the issue (trending to infinity). In such case it's important to reduce or even remove it's impact
Many simple applications don't use the derivative and just stick with P (Proportional) or PI (Proportional Integral) control as it is just too tricky to properly implement.
Yeah, but options are only one financial derivative and they are based on the value of the underlying security such as stocks, indexes, and ETFs. The performance of the stock market/economy in general will definitely have some effect on options trading, but from my understanding, the same wouldn't exactly apply the other way around (or at least not in a direct manner). There are A LOT of regulations when it comes to trading options. FINRA requires that each customer of any brokerage must be specifically approved (or disapproved) for options trading. Brokerages can require a minimum $ amount in order to apply for options trading, and brokerages often have different levels of what they allow based on risk. For example, 1) purchase of puts and calls only 2) uncovered put/call writing 3) options spread transactions (from least to most risk). There are also 5 requirements that a stock must meet before it can have options. During a recession or market stress, I would expect the sellers to price their options contracts accordingly and the buyers to be aware of the increased risk depending on the type of trade for the most part cuz every1 tryna make money. Like trading risky options on margin during a recession wouldn't be the norm. I'm not super knowledgeable on finance, so I might've made incorrect assumptions. Feel free to correct me if that's the case. A case where what you said is correct and my explanation might not apply would be the 2008 recession, but it wasn't due to options really and instead due to several factors that became a domino effect. Instead of options and speculating the price of stocks, it was real estate prices that were speculated to continue rising. The little government regulation in the mortgage-backed security market and agencies falsifying the low risk of those investments led to huge demand from investors and risky subprime mortgages increased to cover that demand. Even though some investors knew that the mortgages that backed their investment were meant to fail, as long as real estate prices kept rising, both investors and borrowers would be bailed out.
Exactly. Financial institutions build up reputation in the good times and then make us all pay for it as soon as their equations stop working.
Finance as an industry is parasitic and cancerous.
I did a PhD in it (2008 - 2012 at the University of Sydney). Black and Scholes got the maths wrong by holding the portfolio flux fixed flat at r, debasing it of market return mu with a surreptitious slack variable (from the constraint on the portfolio returns). This means that the formula is systematically inaccurate in that it underprices calls (upside) and overprices puts (downside). The need for implied volatility is the (inadvertent) admission that the formula is wrong (because it does not contain mu). The binomial model perpetuated this nonsense of not having market return mu in option premiums by removing the flux by changing p (also by debasing the portfolio flux). Apparently someone forgot to check the risk and return properties of that model (noting that binomial variables are already under-dispersed and financial markets are intrinsically over-dispersed). Not having mu in option premiums is essentially financial communism.
Do you have a paper about it?

Worked in the OTC derivatives industry for years, and did many training classes. A great video. As an interesting personal note, I once worked with a quant group who had Fisher Black's old office, which had been turned into a "fish bowl" type group work space. It was a great partner's corner office, but no one would take it, hence being turned into a team office. He had only died recently, and no one would take it, as it would have been viewed as pretentious. Such was the esteem he was held in.
lol nobody cares about fisher black, imagine wasting economic space because money hungry people viewed a man like a god.
I would take it, who cares. Offices are for the living. There are graveyards for that.
@@crimpers5543 My point precisely.
@@crimpers5543humans often do things out of respect for those that have exited their field after leaving a lasting impression. We retire jerseys and player numbers on professional teams for great athletes. We make memorial benches at the local golf course that nobody will realistically use and plant trees with a placard to honor those who were important to local parks or communities. A girl in my high school passed away suddenly, and her assigned parking space at the school remained untouched and reserved for her for the rest of the year, even though all parking passes were sold out and there was a decent backlog of those wanting one.

I've traded passively for 16 years. I did it heavily at first when I sold a business I started, thinking maybe I could use some of that sale value to make more. I lost a huge chuck of it and traded lots smaller with disposable income only from then on. Each year I net about 5-8% growth because I learned something that this video touches on with the 'Radiation of Probabilities'. People often look for big fast wins, but the reality is you're looking for medium slow wins. An example is CRISPR. I watched China and Europe gain interest in genetic research, and the USA laxing their stance about genetic engineering with fetuses and crops. I bought in late 2018 around $51, and sold it when it spiked in 2020 at $160-ish. This was a huge win. One of my biggest.
Sorry for the long reply, but you had a soft interest in this, and I think my anecdote is worth noting for you. As long as you never invest more than you can afford, are confident enough that your prediction is sound, and are willing to lose the whole balance, trading can be real fun. If you go all in, you will not sleep.
all of this is not applicable in real markets. you go bankrupt very quickly if you try. Black-Scholes is like a war plan - it never survives contact with the enemy. LTCM was the first jab at it. and it went great, didnt it? :)

You're overdoing it.
In terms of making the actual _understanding_ accessible to the average person, this exposition was a flop. I don't want to be "blown away", unless the aesthetic is the point, and the journey is more important than the destination.
@@-danRWhy not? I didn't know what options were before this video (even though I've seen the big short and margin call, heh) and now I'm sure I have a somewhat decent idea of what they are.
This is the first time I felt that it is worth spending some time watching this video and also share. Have watched other videos and I was critical before on some aspects. This is very matured video production.
Inspired by this, I went on to study this topic in MIT's online course 18.S096. Turns out the math background is intense and it must have been really hard to fully explain it 3b1b style. Along the way I realized quant math is so similar to what I learn in a ml ai cursus, pretty cool!
props to Andrew Lo, explain it very very clearly.
he was amazing.
Veritasium liked your comment.
As a computer science engineer I cant seem to ask if: is the Bachelier normal distribution related to binary 1s and 0s? Because in each distribution it can go only up or down, there are only 2 states. Like in binary you represent more proportionally to the number of paths taken, up or down, 0 or 1. Can anibody answer me if these are related?
He understands and explain things so well, he should be a professor. edit: he is
Agreed. That was probably the best basic description of the options market I've ever seen outside of a book. Reality is more complicated but the bedrock upon which the system is built is very clear here.
One big elephant they left out is the secondary derivatives market. A dangerous behemoth lording over society like a sword of Damocles.
That's where "too big to fail" comes from and it's still happening far worse than it was in 2008. It's bigger and more failure prone than ever.
The pandemic several years ago could have been that "black swan" but governments dug those pockets and went deeply into debt (to private entities btw) to prevent a catastrophic failure.
The truth is that something similar will inevitably happen again. It's only a matter of time and there's only so far you can kick the can before you lose the one thing keeping the entire edifice of the system together. Faith in it. When the people lose faith in their money, especially all at once, no world war can match the untold suffering in the wake of it.

I think it resonates with me more because this is how I trade. I obviously do charting and predictions, but every trade and safeguard more importantly is based on the probability that it's just as likely to do up or down.
"Drift" as you call it is the part unexplained by physics though, and everyone uses their own.
Great vid, just missing the contribution of Prof. Paul Samuelson when he visited the Univ of Paris and found out Bachelier's PhD thesis full of dust and lost inside the Library, by then....Fisher Black and Myron Scholes were struggling to find a solution to their SDE, so Samuelson helped them a lot by presenting Bachelier's approach. In addition, Itô's calculus was also used by Prof. Robert Merton to make his contribution mathematically elegant and robust.

Combining it with visual represantations of the hard to grasp statistical phenomena makes it even better. Loved every minute and made me wish my Derivatives professors would have had the same passion for the topic. Bravo, coming from an MSc in Finance!
I still dont understand it lol
Business logic and jargon makes my head explode, and this particular exposition, after Thales of Miletus, quickly became pedagogical nightmare.
I need to know the tensile strength of an option; let's start at the beginning and work our way forward.
@hanswurst7325 except for the fact that he got several things wrong then yes decent video since most people wont know
@@roccoVALwhat did he get wrong?
Yeah, I've read a lot about this topic but the way he presented it here made it even easier to understand it.
One of the most excellent explanations of a complex subject I have ever seen. Keep doing what you are doing!
this is one of the most knowledgeable and interesting CZcams video I have seen in a long while .
I have been subscribed to your channel for a long time and I want to thank you for your constant research on various subjects. It's always pleasant to watch your videos.
Genuinely one of, if not, my favorite channels for years now. Thank you for the quality educational videos!
I personally dislike trading, because it is pretty much gambling for normies while sophisticated advanced banks or corporations or few very smart people, or also stock brokers pocket the money, while the money comes from the poor normies that had some hope of making money but lost it in the gamble, or some big corp making a wrong bet! You really have to be an expert mathematician to figure out markets with an average to your benefit and yet some meteor hits earth, and you lose everything!
I always say: invest in yourself. If your investment pays off in shape of great job or product or art, you win big. But even at the worst outcome, it was a training session you paid for.
Yes master
the biggest problem in stock market is when government steps in to bail out people with newly printed money, which inflates the currency and causing prices to rise, effectively "taxing" everyone else in the economy to save some stock gamblers funds and banks.
If it wasn't for that, I wouldn't care if traders are losing money.
You smell like exit liquidity. Please don't self-project your limited understanding of the Jekyll and Hyde system that is "The Market". Anyone can be a successful trader if they manage their capital properly, understand statistical variance, and actually do the research to understand why they're buying into whatever asset class they decide to invest in. It's easy when it's a passion.
Day trading yes. However index funds held long term are a great investment.
@_Syn You forgot one thing: lots of other investors who are dumb enough to think a few stats courses, thorough research, and passion is enough to make it easy.
Actually, sorry, I guess you did remember that.
This is an excellent video... as a Material Physics Grad who is pursuing an MBA I can relate how the random walk from the diffusion models can be used to calculate returns on Options.
Derek,
I am so impressed with the quality of teaching and communication of this video. You have every right to be very proud. I’m 64, consume huge amounts of information daily and am rarely impressively struck by the lucidity and insights and especially with the order they are presented. It’s as if you could read my mind. Each time as I began wondering something, you presented that exact thing - as a question or factoid.
Friggin’ marvelous.
❤👍👍
I remember having a consultation with a financial analyst last August, and it was incredibly insightful. Can’t stress enough how helpful experts in this field are!
Absolutely agree! A good financial analyst can make a world of difference. What specific insights did you gain?
My colleagues had a good laugh at me when I told them I started my journey with $5k capital and how I accumulated over 5 figures within a span of 7 months. They never believed me until I pulled out my P&L.
As long as you diversify your portfolio, any single stock or investment that you own shouldn’t have too much of an impact on your overall return. If it does, diversifying might be the right choice for you, as one can also try out other commodities. I now have a balanced portfolio that is yielding me profit thanks to guidance from Jonas W. Herman.
Hermanw Jonas (a Gma!L comm
Is he taking commissions for his services? Yes, I’m I still making money in the process. Most definitely!
Jonas’ analysis isn’t just about short-term gains; it’s a solid long-term strategy. I have had great relief working with him as my previous experiences with others was dreadful.
Thanks for the advice, both of you. It’s reassuring to hear positive experiences.
I feel more confident about moving forward with Herman now. I just shot him a mail. Thanks for sharing your experiences!
Finally! Thank you for educating people about stochastic calculus. I feel seen :)
Btw. stochastic calculus is nowadays used for more many things non-financial (natural sciences including climate modelling, machine learning, etc.)
As a side remark: a process satisfying the equation at 21:05 (the price of a risky asset) is called geometric Brownian motion.
Ito calculus, baby...
In a lot of the types of real world applications you mention, stochastic calculus is considered a necessary part of statistical mechanics. A good way to think of it is that motion, such as zones in weather moving over regions, are breaks in equalibrium. We expect randomness, but self enforced behaviours cascade into some amount of predictability.
I found your videos at the worst time of my life and I must say, you are my most favourite CZcamsr, you have no idea the change you have just brought in my life, after being scammed multiple times trying to have extra income. I appreciate you so much. And may God continue to bless you for being such an amazing soul. Thank you Evelyn Weston.
I traded well on my Demo account but when I invested into my main account i lost all my funds. Please i need an expert to assist me with my trade. It's frustrating how people loss funds in this market, I really feel so bad.
Such market uncertainties are the reason I don't base my market judgements and decisions on rumours and here-says, got the best of the year and had me holding worthless position in the market, I had to revamp my entire portfolio through the aid of an expert trader before I started seeing any significant results happens in my portfolio, been using the same expert trader and I've scaled up 175k within a year. 11:32
This is so Inspiring.
You've just given me little guide on how to invest in a healthy way as you doing currently thanks.
Yes, transportation, e-commerce among other sectors are expected to experience growth, but who knows, the market has been a basket of surprises.

He’s done it with this one. GOAT of CZcams science videos
Man, your style of presentation and handling of complex subjects is truly impressive!
Thank you for yet another amazing video.
Yea bc its fuckin wrong 😂😂😂😂😂😂😂😂😂😂😂

Is an Essay, esse (that's what she said anyway.. 8===D )
Good overview and informative. I would like to see a follow up on this subject that considers entropy.
It is one thing to throw random mumbo jumbo words in a video but to explain it at such great length
you are simply brilliant.
great video as always
❤
Please please please please do more financial videos like this!!!!! I don’t even care what the topic is, just do more breakdowns like this! Love it! Great job!!! ️
I'm new on this completely, I'll try it 4 sure. thank u amigo for sharing this strategy.
Prof. Andrew Lo puts on a clinic in explaining something in a way that is strictly correct yet broadly accessible.
Lol, so you just overlooked professor Andrew Lo's aping mannerisms, which he had to acquire to establish his credibility in the "free world". Every twitch of his head is broadcasting loud and clear that he's no serious thinker
Well that should be easy when you are simply mimicking what Physicists, mathematicians etc. have spent the last 200 years deciphering... Also their goal was not to explain it verbally but mathematically, while he is simply explaining what they did.
Absolutely mind-blowing how the concepts of randomness and probability can have such massive financial implications. The development and application of these mathematical models, and their role in shaping modern finance is a clear testament to the power of mathematics and science in deciphering patterns amidst chaos. It's remarkable how these game-changing theories extended their reach beyond academia all the way to Wall Street, instigating the rise of multi-trillion dollar industries.
Math is an amazing subject, but it's reputation has been damaged by the flaws of the school system.
Is this chat gpt?
@maxemore That was my first thought as well haha. The account seems to make a lot of AI generated videos.
I am thinking this is ai written comment but I couldn't really put my finger on why do I think so.
Check out the book "When Genius Failed" by Roger Lowenstein. It explains Black-Scholes, what happened when the laureates built a company using the equation (and had to be bailed out by the Federal Reserve). Surprised Derek didn't cover this.
My goodness, I'm not at all into mathematics or finance, but I didn't once have to pause or rewatch in order to understand this, so well explained is this! Very well done.
I now finally understand the difference between a call and put option. My hedge fund is gonna do really well this year
That was a very awesome and interesting episode. Hope you'll do more non-physics things in the future the same way!
"hope you'll do more non-physics things in the future the same way" Only if man made things were more interesting than the nature!

Just wanted to let you know that Jesus loves you and he delivered me from a horrible po - rnography addiction after doing three 24hr fasts.
I was struggling really bad with this addiction and I decided that I'd fast one day. Funnily, my first fast accidentally ended up on Mother's Day, so I was sitting in a nice restraunt with my family and I was the only one not eating. But the Lord blessed me for it. After that fast I was free for 2 months and I had never been free for more than a week at the point. But . . . I relapsed again.
I fasted once more and this time I was set free for around a month. But . . . I relapsed again. Then I gave up and tried to overcome the addiction on my own for a few months which DID NOT WORK.
Eventually I decided to fast once more. This time after the fast God gave me a dream:
I was I a forest and a bear charged me from my left handside. I instinctively put up my left arm to guard my throat from the bar which worked. The bear quickly chomped on my arm and broke it. The force of the bear brought me to a one kneed stance and there appeared 2 entities of fear and doubt around me and they wanted to enter into me.
But I said "No. Like David and Samson before me"
- For context In the Bible David killed a bear and a lion and Samson killed a lion
I then grabbed the fur underneath the bear's jaw (How it says David did when he killed the bear 1 Samuel 17:35) and ripped the bears jaw off. The bear fell back dead and I awoke.
I didn't immediately realize what the dream was about but I soon would. Not more than a few days later I relapsed *AGAIN* (my arm was broken by the bear). However, immediately after every urge and desire to engage in those activities left me. I have since been *COMPLETELY* free for 1 year and 2-3 months (Nov 2022)
Jesus really Loves us and despite the Biblically abominable things I engaged in and encouraged others to as well he saved me from one moment to the next.
Repent, Forgive as you've been Forgiven, Love your neighbor as yourself, and Love Jesus with all your heart, soul, mind, and strength.
No matter where you're at God can still save you and wants to.
Just start reading the Bible, praying, maybe throw down a fast here and there, and let God lead you to the church he wants you at. You're Life WILL CHANGE.
God Bless You with Salvation and Deliverance In Jesus Name!
If you have any questions about my testimony or Jesus I'd be more than happy to answer :)

But everything's physics. It's just subdivided into different fields of sub-specialization. Even the way biological systems work, the biochemistry, the interactions within ecosystems, those are all founded in physical principles
@Veritasium Great video and explanation of Black-Scholes / Merton, but I'm severely disappointed that you didn't bring up the story of the hedge fund "Long Term Capital Management". This is an example similar to Renaissance / Medallion, but an instance where it goes terribly wrong.
I find it especially disappointing that LTCM isn't discussed in this video because Scholes and Merton were both founding partners and on the board of LTCM when it failed terribly in 1998. When LTCM failed, it was a serious threat to the entire financial system and required a bail-out of $3.6 billion.
Your video ends on a note which suggests that with strong enough math, data, and computational power - you can beat the market. The story of LTCM says otherwise. I really think an addendum to this video is merited...
@Veritasium this, deserves a part 2
Agreed. That was a very sanitized discussion about the downside of the insane leverage that derivatives create. When it goes wrong, it doesn't just lose these hedge fund managers money, it costs people their retirement savings, their houses, and costs the government (i.e., the taxpayers) billions of dollars to bail these companies out. Privatized gains, socialized costs.
Yeah. The story of LTCM should have been mentioned.
I thought the LTCM fund was doing bond trading, not derivatives. Anyway, would still make a good video.
@@ianglenn2821 correct. but regardless of the assets, their approach, talent recruitment, and overall strategy to trade such assets was what is discussed in the video.
This was an awesome and amazing video explaining many concepts that I now better understand than when I learned them in school. The visual effects and animation is so much better than what a book can offer. Simply Excellent!!!
I don't have a deep understanding of this stuff but the last sentence at the end of the video made so much sense suddenly.
Derek is the only person I will gladly let confuse me with math regarding a topic I loathe (finance/econ) for a half hour. 10/10 love the animations.
As someone who started tradin options just 2 weeks ago, this video was the best thing I have seen this whole year!
Did you catch the part about being a mathematician and needing massive power?
@@Elemblue2 Depends on what you believe your comparative advantage to be.
Trying to predict momentary price fluctuations is probably unfeasible, but if you believed yourself to know something much better than most other market participants, you could trade based on that expertise and be profitable.
In theory. In practice, it is difficult to believe an individual could find market inefficiencies with the massive amount of money and effort already directed that way...
...which might have screwed me. Or saved me - I had an idea for trading options on a relatively short (2-6 day, say) timescale, and back-testing appeared to validate the model, and...
It worked! Seemed to, anyway. After a few months, and tripling my starting stake, got cold feet and quit.
I still wonder, though...
@@Elemblue2 He will be the one that makes large earnings possible. For others, of course 😁
Most traders are massive alright
I started options trading this year with the goal to a million dollars. Now I only have 2 million dollars left to make!
You're an amazing educator, sir. Thank you for creating this video. A fascinating topic.
This video had covered a very important concept in finance. Thank you.
I highly recommend the books "Physics of Wall Street," "Fortune's Formula," and "The Man Who Solved the Market" for more on the pioneers and history of quant finance. Really interesting reads that touch on a lot of the anecdotes in this video, and more.
So excited lol. Derek, you are the best. I loved the video that you posted about blue light. And you are back with another banger.

Wow!!! Finally a descent video that explains option trading!!! Been waiting for something like this.
I was curious whether you could buy options on options on options (...) on options on regular stock options, and found out that yes, they are called sequential compound options. The complexity of these is insane. So I guess the search for optimal option pricing formulas will go on forever.
2:30 OH man, how the tables turn! Loved the pun!

Hats off. Absolutely brilliant exposition
I remember when Priceline was first in business. It offered "name your own price for airline tickets". The market capitalization for Priceline quickly became larger than all the big airlines whose tickets it was buying and selling. This struck me as insane at the time and I'm glad I didn't sink any money in the stock when it made its first big splash!
Bitcoin is on its way to breaking records, getting closer to hitting new high prices, showing that it's gaining more value and could go even higher than we've seen before.
