Can someone please explain why our indicators are independent from one another? Doesn’t the fact that n is a maximum influence of n+1 can also be a maximum?
Hello i see alot of mixed opinions on this topic regarding wether a mfe is worth it and what undergrad one should do. In my country they recently opened a Undergrad in financial enginering and i was wondering what education should i pursure. Should i do just an undergrad, should i do undergrad in math or stats and then an mfe or should i do an undergrad in fe and then an mfe. Would really like to hear your op on this.
Bro im an Economics major and CS minor and hope to go to America to study for my Master's. Will i be able to break into this field with a Masters in Financial Engineering? Or do i need to do a PhD as well?
well , big firms often like to hire more math/stats/cs grads and sometimes physics and some engineering(civil , chem , ...) because they got the quantitative skills needed for this kind of job, i've seen some MFE graduates and they did get hired by some mid firms , but if you're aiming for top firms just take more cs and math classes and stay away from economics ones , and do a masters in statistics or cs or any quant major
And after all of that they still can't beat the S&P 500.
Nah this is crazy
hey how hard is it get a job if u dont have masters lets say u only did a degree in math or math in stat
Bro had DE&I in his stick figures 😂😭
this video feels racist, but it's great
Bfs
the racism is crazy af
Good Explanation. You showed local miminima instead of maxima for the triplet arrangement

Hi, is there any book you would recommend?
Depends on what your looking to learn: stats, cs, etc Here's a stats textbook I recommend: probabilitybook.net And here's a good resource to learn c++: www.learncpp.com/
the reasoning of +1 and -1 for the HH case is not correct, it only worked out (by chance) because the coin is fair.
I did not like that rationale either. What is the correct reasoning for it being x again?
if it's always a convex quadrilateral, why is the probability of choosing a convex quadrilateral not 100% ?

How can non target university students got this internship
You need to find other ways to stand out whether it be through projects, placing in competitions or achieving some resutls (published papers, project with users, high codeforces score, etc)
the african dude is charcoal black ...supp homies😭😭😭🤣🤣🤣
Why 114 ?
Can't you get this type of jobs with Finance or economics degree?
you need math this is probably the most applied mathematics and statistics job you can get the whole job is about calculating statistical probability and risk in free markets using math and risk models you will be using the highest level math classes and if you want to stand any chance, you have to start learning math from the beginning and don't give up. finance should not be your major for this role.
Thank you for your advice. Do you think it would be better for my career if I study Computer Science for my bachelor's degree and pursue a master's in Financial Engineering, Computational Finance, or Financial Mathematics? Alternatively, what about studying Economics for my bachelor's degree and self-studying programming and additional mathematics, followed by a master's in Financial Engineering or a related field?
@@eddiekiller21 Thank you for advising me Do you think if I study CS at bachelor degree and getting a master in financial engineering,comptentiual finance or financial mathematics it would be better for my career? What about studying economics at bachelor degree and self study programming and extra math and get a master again in financial engineering and etc?
Hey QQIO, great stuff - I finished my undergrad in Economics at UC Berkeley and am working while doing an M.S. in Computer Science at GeorgiaTech - any recommendations since i missed that Undergraduate recruitment window :/
You can still get internships in your masters/pHD - these firms hire across the board I'd say look into competitions held by firms along while making one really in depth project that showcases your interest. From there it's simply practicing questions on the site and competitive programming (if you're going for quant developer) Hope this helps :)
😍😍😍
Great video man! I am doing a master's in math - t30, Russell group uni, but my internship experience is in not in a relevant field, how do I proceed ahead if I want to break into quant
My best recommendation is build out a project that shows your interest in quant finance, I'd even put it above my professional experience on my resume to highlight it. Here's an example: Statistical Arbitrage Project - it'll go from strategy generation, data sourcing, signal construction, backtesting, performance evaluation, weighting, optimization of strategy, etc -- this would be a bigger project, but depending on your timeline you can make a different one. Another idea is to try placing in a firms competition, some friends of mine did quite well in IMC Prosperity - other firms definitely have similar competitions. If you're aiming for Quant Developer - another idea could be focusing more on competitive programming, (code forces red is a good goal) Goodluck!
whys the asian still yellow 💀
fire video 🥶🥶👍 how competitive are the freshman/sophomore programs and what would maximize chances of getting in?
Thanks - as for your question, its quite competitive, if you're a math olympiad or have done well on large math/cs competitions (e.g IOI) your chances are higher. That said you still have a good shot if you build a decent foundation in statistics and have relevant projects on your resume
is this moon? lmao
Shouldn’t it be 144?
I persuing financial engineering in University.
Thank you for this video and hope your best in the future. Im asking that if my major is finance and im interested to be come a quant resếarcher. Is it possible for me from a background like this ?
I did it by this: x_1 = value of first role x_2 = value of second role given P(x_2>x_1 | x_1 = k) = (6-k)/6 then i did a summation across k and multiplied it by 1/6 but i think this is just an algebraic version of the manual method :(
Checkout solution 2 in the video 1:50 - a much cleaner solution imo
I agree. But how well does that approach scale to the more difficult questions. I think being familiar with summing across the combinations is good practice for when you get to things like the 20 and 30 die question
Hey man im a planned physics major can i break into quant
Heard physics majors break into finance but Quant is a completely different ballgame
I could only thought If last move is 50 at my turn then in the privious total..it must be 50-k ie around 40+..so my goal is to bring friend at a number between 40 and 49 so that in next move I win..but I couldn't derive how I should pick a specific number at first am I half witt or low IQ for the job?
I mean you almost got it - if your friend must choose between 40-49, then if your 39 no matter what your friend picks he will be in this range Don't beat yourself about that though your thought process was correct, just practice more on quantquestions.io and that'll help to build your confidence. Some problems tend to have patterns to them, so even if you didn't get this problem, similar problems will now become easier. Good luck and don't give up!
yes, to get ur friend to get a number between 40-49, you end your turn at sum 39, so that his range of sums is 40-49. keep doing this downwards, to get him to 39, you end turn 28, 17, 6

1:55 Good afternoon, I am in my sophomore year of community college taking Business Analytics with average math and I am interest in Quant Finance. While i was initially drawn to IB or Private Equity I recently fell in love with math despite my gaps in my education due to inmigration. Do you think it is realistic to start this field on graduate school successfully?
Take a math minor and pursue a masters in stats or applied maths
@@will-ti2qs Done! I declared Business analytics with a minor in Statistics for my transfer school. Depending on how it goes I might convert the minor into a double major, any feedbacks?
As I experienced and talked to some of my seniors who got into quant , statistics(model based quantitative skill) seems really important for this industry. Grind statistics as much as possible and pursue MFE or other related majors after your undergraduate would be the best idea!
@@Ill_0823What’s MFE

@@nicolocantaluppi5572 gonna be straight up, don't know if you can make the shift. Math is going for you but massive gap in finance knowledge and experience
Why tf would you want to go for a quant?? You studied physics for christ sake , go work for nasa or some shit
Continue with the great work, Emma!🏔
So basically impossible for anyone past bachelor's and masters in finance
You need to be good at math
I heard quants are the gold Olympiad medalist, geniuses that got full-rides to Harvard for reinventing E=Mc^2. I mean how competitive is it to get in
You just need to study for 10 000 hours. Quantitative rigorous 4yr undergrad + extra readings and practice + ( personal project or work experience ) + interview prep = (4yr x 50hr x 40weeks formal education ) + ( 600hr in textbooks or certifications)+ (200hr x 4projects) + (600hr leetcode, olympiad math)

Hey man really informative video.I study chemical engineering and I want to study an MSc in quant finance later on. Will I have a strong background for landing a quant job ? Thanks in advance
I think the MSc will serve you well, but before that a very important quality for quant jobs is having a good affinity for mathematics Hardvard has a free Stats 110 course online that we always recommend, so I'd recommend finding out if you like maths and can learn it well before pursuing a quant job
Bachelor in Econometrics, math or physics for quant role?
Math is in our opinion the best foundation to have, along with statistics
They don’t just ask “mathematics questions” they ask the hardest questions known to man. Most of the time, with some arbitrary trick that you have to memorize.
its not THAT hard, most of questions are straight up from HS level math competitions

Imagine the software that could have been built if the amount of energy put into trying to beat the market was re-directed into other projects. I hate how powerful money is honestly.
keyword: imagine. you can hate money all you want but at the end of the day you're giving the channel money by watching and money will still stream regardless
@@kushpenguin my contention went over your head entirely.
I say people are already doing that, look into Andrew Youn and the One Acre Fund Definitely an instance of putting great minds to work on important problems
But these industries create huge demand for highly distinguished problem solvers, and select them based solely on merit - with highly abstract transferrable skills into any STEM domain. If it wasn’t for these huge rewards, what else would motivate millions of scholars towards computational sciences? I agree money is too powerful, but in terms of pondering efficient allocations of capital, what about the billions spent into the entertainment industry? The effort gone into hosting sold out Taylor Swift concerts, Superbowl, Champions League, K-pop, and Bollywood, for I’d argue those costs create less value for society than even the investments industry. My point is, the best synergies/productivity happens when we let people do what they want to do, and let people pay for it… For we all apes afterall… So there will always be stupid spending, humans love singing women and wine. More importantly there will ALWAYS be conflict, and more fundamentally competition over finite resources, thus we have geopolitics, and that’s all business and money. If you want to solve this big money problem, we need to have world peace; or world domination.
Maybe it says something about how relatively important beating the market is. So this would imply that efficient capital markets are very important for a modern economy.
