क्वांटिटेटिव फ़ाइनेंस की गणितीय नींव और अध्ययन-पथ
सारांश
दस्तावेज़ एक ऐसे गणितज्ञ के प्रश्न का उत्तर देता है जो क्लासिक शोधपत्र, खासकर स्टॉक मार्केट मेकिंग पर, खोज रहा है। एक उत्तर पहले व्यापक गणितीय नींव बनाने की सलाह देता है: माप सिद्धांत, वास्तविक विश्लेषण, संयोजनशास्त्र, बेयज़ियन विश्लेषण और निर्णय सिद्धांत। यह विषय-विशेषज्ञों के साथ मिलकर वित्त और अर्थशास्त्र सीखने की सलाह भी देता है और लेखांकन को उपयोगी पृष्ठभूमि बताता है। दूसरा उत्तर गणितीय वित्त के एक सामान्य संग्रह और बाज़ार सूक्ष्म संरचना के व्यावहारिक परिचय की ओर संकेत करता है।
यह मार्गदर्शन व्यवस्थित ग्रंथसूची या विशिष्ट शोधपत्रों की तुलना के बजाय अनुभव पर आधारित है। यह सावधान करता है कि कई मात्रात्मक विधियों के समर्थन में मज़बूत अनुभवजन्य प्रमाण नहीं हैं और उनकी धारणाएँ टूट सकती हैं; उदाहरण के रूप में मूल GARCH अध्ययन का उल्लेख है। व्यावहारिक सीख यह है कि किसी विधि को लागू करने से पहले उसकी धारणाएँ और वह जिस समस्या को हल करने के लिए बनी है, समझें। उत्तर विस्तृत मार्केट-मेकिंग पाठ्यक्रम नहीं देता, सुझाई पुस्तकों का मूल्यांकन नहीं करता और यह स्थापित नहीं करता कि लाइव बाज़ार में कौन-सी विधियाँ काम करती हैं।
मुख्य विचार
- क्वांटिटेटिव फ़ाइनेंस में विशेषज्ञता से पहले गणितीय नींव बनाएँ।
- संयोजनात्मक तर्क उन समस्याओं का आधार हो सकता है जो सांख्यिकीय मॉडल माँगती हुई लगती हैं।
- किसी विधि पर भरोसा करने से पहले जाँचें कि उसकी धारणाएँ डेटा और प्रश्न के अनुकूल हैं।
- गणितीय विश्लेषण के पीछे के उद्देश्यों को समझने के लिए वित्त विशेषज्ञों के साथ मिलकर काम करें।
- सामान्य गणितीय वित्त और बाज़ार सूक्ष्म संरचना के संसाधनों को संभावित शुरुआती बिंदु मानें।

# What are some classical papers to read for a mathematician looking to get into quant finance? # What are some classical papers to read for a mathematician looking to get into quant finance? While searching around for some market making-related stuff I bumped into this paper https://arxiv.org/abs/1105.3115 and thought that I'll start digging through it and its References, out of lack of better ideas. I doubt that's a particularly effective way of approaching this, so could someone give me a better list of papers to get started with? I'm particularly interested in the theory of market making strategies for stocks, but will happily read any "classical" works in the general "quant finance" area. ## Answer by Dave Harris (score 5) https://quant.stackexchange.com/a/34487 The field is in flux right now. Since you are at the master's level I think you should focus on more general works in mathematics. If you were my student and we were ignoring specific things such as securities analysis and accounting and focusing on the mathematics, I would recommend you begin with measure theory, real analysis, combinatorics, Bayesian analysis and decision theory (both Bayesian and Frequentist). It's important to understand that a lot of stuff used in quantitative finance lacks empirical support. Think of other categories of problems such as the difference between two means. Depending on your precise assumptions there are only a few possible tools and only two or three should be operative at a time, one Bayesian, one Frequentist and one Likelihoodist if it differs from the Frequentist. Once you have selected your interpretation of probability, there should only be one choice open to you. In quantitative finance, there are tons of tools and each one is being proposed because it is not clear what to use. Tools range from OLS to GARCH, to fractal based analysis, neural networks to data envelope analysis to random forests and you can get a long list in the literature. In just one category I did a review on I found 26 techniques. You want to stay out of the weeds AND stay out of most of the foundational documents. To understand why you need to stay out of the weeds consider that GARCH is big right now, but in the very first GARCH article they ran a test on stocks and found that stocks strongly violated the assumptions necessary for GARCH to work. Even though it is not supportable, neither are most things, so why not use it? Go to one of your advisors or to a librarian in your academic library and start with a book on measure theory. I am not going to recommend one, but instead, suggest you talk to people about it where you are at. There is an advantage to face-to-face conversation. Then pick up real analysis. You can flip the order. As you start getting into this you will find that many of these problems are really combinatoric problems. Lots of the solutions really attempt to go around the combinatoric issues. Then I would pick up an introductory book on Bayesian methods and an introductory book on decision theory. As you get into the field you will find someone needs you to evaluate a neural network or an ARMA model. I recommend the physicians' command "first do no harm." You are an expert in the math and not in finance or economics. Listen to them, dig deep into what they are really needing from you and what their goals are. Be as good as you can at the base math, then build into finance later. PS It wouldn't hurt you to pick up an accounting textbook either. ## Answer by zer0hedge (score 3) https://quant.stackexchange.com/a/34214 I would consider "Aspect of Mathematical Finance" as a starting point for a "general quant finance area". It is > A collection of essays written by leading experts in the field of finance mathematics For "market making-related stuff" I would try "Market Microstructure in Practice"
