Review

"Laurent conveys a determined passion for the short side that has driven him for over a decade. From choosing to enter or exit a position, to managing risk and position size, to visualizing and managing a whole portfolio, Laurent breaks down the process and psychology behind developing an effective long/short trading strategy. He also includes versatile source code in Python, which can be implemented on any stock, in any market, with the sole intention of limiting loss, and yielding above average returns" Michael Covel, Entrepreneur, Author and Host at Trend Following Podcast

"I read with satisfaction that Bernut's book on short selling has a whole chapter on the pitfalls of short selling, describing perils such as short squeezes, sky-high borrow fees, and more. It is an excellent education for traders who are serious about generating alpha from short sales. Highly educational!" Ernest Chan - Founder, PredictNow.ai Inc
