    The story of Jane Street X Millenium battle over the 1 Billion Dollar strategy 👇👇 Last week, In a high-stakes legal battle, Jane Street a proprietary trading firm accused Millennium Management and two former employees of stealing a secret trading strategy that netted $1 billion in 2023. The strategy involved short-term options trading in India, a detail accidentally revealed in a Manhattan federal court. During a court hearing, Jane Street tried to keep the details of this strategy secret, arguing that revealing more could let competitors copy and weaken their successful trade. Despite Jane Street's efforts to keep the strategy confidential, Judge Paul Engelmayer denied their request for a restraining order, citing the strategy’s previous coverage in the media and government reports as evidence it wasn’t as secret as claimed. The two ex-employees, Doug Schadewald and Daniel Spottiswood, and their new employer argued that market conditions, not any stolen secrets, led to changes in profits. Millennium, trading much less than Jane Street, made only $4 million compared to Jane Street's $185 million in the same period. The hearing ended with no restrictions on Millennium, allowing them to continue trading. This court case highlights issues of secrecy and competition in trading, showing how important and sensitive trading strategies are on Wall Street. Both firms are preparing for more court actions, which could further reveal details about the secretive trading world. To think that Indian Markets are so hot right now that foreign firms are churning 1 billion dollars from a single strategy is insane. Let’s us know your take on who will eventually win the lawsuit.

    Quant Researcher @ Five Rings | PhD @ Columbia University | Portfolio Optimization and Quantitative Trading | Convex Optimization

    I wanted to share some book recs that helped me immensely while preparing for quant research interviews. There are loads of book recommendations out there: 1. Stack Exchange(https://lnkd.in/eTtNDNN9) 2. QuantNet(https://lnkd.in/eVmZWAzW) 3. Giuseppe Paleologo (https://lnkd.in/evzH5Vnk) or Christina Qi (https://lnkd.in/eMTEf5a5) Most book recommendations I've seen are great if you are already a quant or if you need an introduction to a new area. Moreover, they are typically very long and are meant to be read slowly. An average of at least 500 pages, taking a few months to read. If you are a student or someone who is interviewing for quant roles, these books are not quite useful. You are not expected to know a lot about finance. You are tested on probability, statistics, linear algebra, programming, etc. You may have already studied some of these topics in school and just need a quick refresher before interviewing. Here are three books that helped me during my interview season. They are each less than 150 pages, and can be read in less than a week even if you just read 25 pages a day. 1. Matrix Algebra: Numerical Matrix Analysis by Ilse Ipsen (https://lnkd.in/e4WTeGpF). Covers all your favorite decompositions, system of equations and least squares. You can skip the stability analysis sections if you want. Bonus: this book is free online. 2. Statistics and Linear Regressions: Introduction to the theory of Econometrics by Jan Magnus(https://lnkd.in/e9U64g2A) covers everything you need to know about linear regressions. The first 52 pages are available online. 3. Probability: I would recommend 40 Puzzles and Problems in Probability and Mathematical Statistics by Wolfgang Schwarz(https://lnkd.in/eBmMShBu). Great set of problems covering most commonly used distributions. Want to practice Markov Chains? Try Problems and Snapshots from the World of Probability by Dennis Sandell, Gunnar Blom, and Lars Holst(https://lnkd.in/eiwEhKS9). This book is about 200 pages though. Both on Springerlink, free if you are at uni. A bulk of my non-programming interviews consisted of these three topics. These books may help in securing a job, but not keeping it. You will need to read/do a lot of things to do a good job as a quant. Here is the same list as a twitter thread(https://lnkd.in/ep2YgQ6t) if you prefer that format. Good luck with the interview season! #quant #interviews #books #quantitativefinance #quanttrading #quantresearch #quantitativeresearcher #hedgefund #proptrading #hft #systematictrading #quantfinance

    Our quantitative researchers deepen our understanding of the markets and drive better outcomes, turning complex abstractions into measurable commercial results. But what does that look like in practice? eFinancialCareers recently spoke with our colleague Will Kaufhold to find out.

    $1,000 invested in Jim Simon's Medallion Fund in 1988 was worth $87.5 Million by 2022 🤯 A $1k investment over this period would've grown to: - S&P 500: $33,033 - Berkshire stock: $159,122 - Medallion Fund: $87,542,697 This is what 39.9% annualized returns looks like 💰 And this is *net* of fees. Simons didn't charge the traditional hedge fund "2 & 20" His fees included: 5% management & 44% performance fee. The greatest of all time.

    Jim Simons, the financial titan who launched the Medallion Fund and achieved an unparalleled 66% average annual return over 36 years! With Renaissance Technologies managing over $60 billion in assets today, Simons retired with a Forbes-estimated net worth of $31 billion. How did he do it? Well, for one, he never hired Wall Street analysts! Born in 1938 in Brookline, Massachusetts, Jim is a legend in finance and mathematics. By age 20, he earned a bachelor's degree from MIT and later completed his Ph.D. at UC Berkeley. After a brief stint at Harvard, Simons joined the Institute for Defense Analyses during the Cold War, where his interest in the stock market began. In 1978, he founded Monemetrics, later known as Renaissance Technologies, with a vision to use mathematical models in trading. At 40, he founded Renaissance Technologies in a storefront office in a Long Island strip mall, convinced that he could predict the market's movements with the same certainty as mathematical equations. Simons is credited with pioneering high-frequency trading (HFT) and automated trading, revolutionizing the financial industry. He was the first to solve the market's complex financial problems using mathematical models, laying the groundwork for modern algorithmic trading. Beyond finance, Jim Simons is the largest private philanthropist for the mathematics community. His Simons Foundation has donated hundreds of millions to support research in mathematics and the sciences, making significant advancements in these fields. Simons's incredible journey is detailed in the book "The Man Who Solved the Market," which explores his groundbreaking work and the creation of the quantitative finance industry. Jim Simons's story is one of brilliance, innovation, and impact. His contributions to finance and mathematics have changed the world, and his philanthropic efforts continue to inspire. #JimSimons #QuantFinance #Mathematics #RenaissanceTechnologies #Legacy #Philanthropy #BestInvestor #HFT #AutomatedTrading

    🚨🚨This mind boggling brainteaser was asked in this intern season's Jane Street Interview. 🤯🤯 The rudimentary method of shuffling a pack of cards is to take the pack face downwards in the left hand and then transfer them one by one to the right hand, putting the second on top of the first, the third under, the fourth above, and so on until all are transferred. If you do this with any even number of cards and keep on repeating the shuffle in the same way, the cards will in due time return to their original order. Try with 4 cards, you will find the order is restored in 3 shuffles. In face, where the number of cards is 2, 4, 8, 16, 32, 64, the number of shuffles to get them back to the original arrangement is 2, 3, 4, 5, 6, 7 respectively.
