Libro: Quant Basics 101: A Beginner's Guide To Quantitative Trading

Quant Basics 101 is designed primarily for students interested in pursuing a career in quantitative trading and/or sell-side researchers exploring the buy-side. It is not aimed at retail traders, though they may find some useful insights.

Quantitative Trading uses a combination of mathematical and statistical models, algorithms, and computational methods to systematically analyze financial data, identify trading opportunities, and automatically execute trading strategies.
Sitting at the intersection of high-level math, intricate analytics, and advanced technology, quantitative trading has a reputation for being a difficult subject, demanding a dedication understood only by ardent financial and tech aficionados.

The book serves as a foundational guide to understanding the principles of quantitative finance: it teaches the essential habits to prevent common errors and avoid obvious mistakes; it offers guidance on how to approach some standard problems; it describes a few elementary examples of quantitative strategies and pinpoints several interesting areas of research. The book deals with the building blocks of quantitative trading. At its core, the book is about Building Intuition.

Primary themes discussed in the book are the research, design, backtest, and implementation of quantitative strategies, including the portfolio construction problem, the importance of risk management, and the danger of overfitting. Other themes include the acquisition of data, standard linear techniques, fixed-income theory, and the trading of volatility.

The book serves as a reference and source of ideas and intuition for quantitative traders, portfolio managers, risk managers, financial economists and regulatory professionals, amongst others, as well as researchers in related areas.
