John Maynard Keynes was a many-sided figure – world-changing economist, architect of the post-War international monetary system, bestselling author, a baron in the House of Lords, and key member of the fabled Bloomsbury group.

He was also one of that rare breed who mastered the financial markets in practice as well as in theory – an expert stock picker and star fund manager, Keynes made vast sums of money both on his own account and for the college endowment fund he managed.

Keynes’ investment principles, refined over decades of investing, represent a straightforward and time-tested framework for exploiting the periodic irrationality of stock markets. In today’s era of profound uncertainty and volatility, the insights of Keynes – a man who lived and prospered through two world wars, the Crash of 1929, and the Great Depression – are more relevant than ever.

This accessible and informative book identifies what modern masters of the market have taken from Keynes and used in their own investing styles – and what you too can learn from one of the greatest thinkers of the twentieth century.
