About the Author.


?Excellent new book . . . demystif[ies] the world of quant investing, and does so in a way that should be intelligible to any thoughtful investor. . . admirably thorough . . . and highly readable throughout. The book has a logical structure, which gradually builds an ever more complete picture of what it is that quants do, how they do it, and what the issues really are that surround quant trading. Much more than a simple "beginner's guide" to quants, and it really gets interesting in the final third, where [the author] looks in some detail at the risks inherent in quant approaches and the criticisms of quant trading?and how to evaluate them. To find out more about how to evaluate quants, read this book.?
?AR Magazine

In "Inside the Black Box," Rishi Narang makes the impossible seem possible: he takes the vastly misunderstood role of the quantitative trading strategy and makes it understandable to those with only the most tenuous working knowledge of global capital markets. How he does so is a sleight of hand no more complicated than patient, consistently eloquent writing, and easy-to-understand, basic examples."
?Markets Media Online

"The book, Inside the Black Box: The Simple Truth About Quantitative Trading, by Rishi Narang, is hands down the best introductory book I've read on the topic. Narang does a brilliant job of explaining (in simple English), how and why quantitative trading works. If you are looking for a primer on Quantitative Trading I strongly endorse and recommend this book."

"In a new book on quantitative trading strategies, entitled "Inside the Black Box: The Simple Truth About Quantitative Trading," Rishi Narang, founding principal of Telesis Capital, seeks to explain with real-world examples and anecdotes what it is exactly that quants do?The book focuses on a few major questions that Narang says are important to understanding the quant world. These include: what is a quant, what are the secrets of successful quant trading, what caused the disasters in quant trading, what role did quants play in the credit crisis, and what is the future of quant trading?"

"You may be skeptical that Rishi Narang will be able to deliver on the ambitious promise of his book, Inside the Black Box: the Simple Truth about Quantitative Trading (published by John Wiley & Sons, 2009). But he does deliver. He tells you, in language that can be understood by most educated people, what a quantitative trading system is and what a quant does."
