3 chaptersMore about the book
Master the complete quantitative toolkit: stochastic calculus and Itô's lemma, Black-Scholes and beyond, interest rate models, credit derivatives, and exotic options. But theory alone doesn't make money. Learn how to calibrate models to market data, understand when elegant mathematics meets messy reality, and develop the judgment to know which simplifications matter and which don't.
Portfolio construction is where alpha meets risk management. From Markowitz mean-variance optimization to Black-Litterman, from factor models to risk parity, understand the frameworks that institutional investors actually use. Then go further: transaction cost modeling, execution algorithms, market microstructure, and the infrastructure that turns a promising backtest into a profitable live strategy.
Whether you're preparing for quant interviews, transitioning from academia to industry, or building systematic trading strategies, this handbook provides the end-to-end coverage you need. Pricing, portfolios, execution, risk management, and deployment: the complete journey from mathematical theory to production trading system.

Meet the community“I am enjoying reading your writings. I appreciate the effort you put into it. I want to drop a note of thanks. Thank you!”
“I would like to thank you for your work. Specifically, the chapter: 'LIME Explainability: Complete Guide to Local Interpretable Model-Agnostic Explanations' was extremely helpful for me in understanding LIME and communicating to colleagues. Your work is inspiring and valuable. Thank you for doing it.”
“I just came across your website where your books are available for free to read. Thank you so much for making this available to the public. This will help a lot of people.”
“I found your book Language AI Handbook's explanations of Transformer architectures and production deployment strategies to be exceptionally clear and insightful”
“Your writing feels like a treasure trove of great material. So, thank you for compiling everything on your website!”
“Really appreciate the way you have explained the concepts. Simple to understand, yet builds up knowledge exponentially, all while reinforcing it with examples repeatedly. I've read the last two chapters `74.Self-attention & 75.Q,K,V` and I've to admit, my concepts have never been clearer. You really are doing an amazing job breaking down maths and complex concepts like a story!”
“Thank you Michael. It's top!”
“I read a few of your blogs on NLP and oh WOW, they really are something, now I exactly know how all of the terms Entropy, Cross-entropy and how it is connected to Perplexity, will definitely read more of your blogs.”
“I came across your collection of online handbooks covering quantitative finance, AI, and machine learning. I wanted to reach out and thank you for making such high-quality material openly available. They are incredibly helpful for my CFA Level II review and for brushing up ahead of ML interviews.”
“Thanks so much for establishing such an amazing community. I appreciate the opportunity to be a learner and a contributor to the community.”
“Thanks for putting cool stuff out into the world.”
“I came across one of your books, Language AI Handbook, and man, I'm loving it. I've read many books but have never found such a comprehensive book on large models that covers everything from start to finish with such depth.”
