After the warm reception of Essays in Positive Investment Management, the author has published a second, expanded edition. It contains, in particular, discussion of the notion of liquidity as the missing element in modern portfolio theory, together with changes in macro-financial regime as key factors for investment strategies. Savings glut, QE glut, and secular stagnation are lasting features that bring fresh challenges. Few people have better insight into investment management than Pascal Blanque. In this important and timely book, Blanque takes a powerful claim for positive investment to avoid fanciful illusions. Blanque argues that the investment world contains many fairytale elements, and shows that confrontation with reality leaves its mark on the theoretical sacred cows of established beliefs and truths. These essays include an objective assessment of the discipline's sacred cows; the effective dynamic of the financial markets concerning value, liquidity, and momentum; anticipation of the return on financial assets; and the reality of long-term investment. Blanqu?emonstrates the importance of better understanding the psychological referential of the subject and of those individuals who interact within this universe of anticipation and imagination.
