Over seven years, 45 of the world's top investors were given between $25m and $150m to invest by fund manager Lee Freeman-Shor. His instructions were simple. There was only one rule. They could only invest in their ten best ideas to make money.

It seemed like a foolproof plan to make a lot of money. What could possibly go wrong? These were some of the greatest minds at work in the markets today - from top European hedge fund managers to Wall Street legends.

But most of the investors' great ideas actually lost money. Shockingly, a toss of a coin would have been a better method of choosing whether or not to invest in a stock.

Nevertheless, despite being wrong most of the time, many of these investors still ended up making a lot of money.

How could they be wrong most of the time and still be profitable?

The answer lay in their hidden habits of execution, which until now have only been guessed at from the outside world.

This book lays bare those secret habits for the first time, explaining them with real-life data, case studies and stories taken from Freeman-Shor's unique position of managing these investors on a day-to-day basis.

A riveting read for investors of every level, this book shows you exactly what to do and what not to do when your big idea is losing or winning - and demonstrates conclusively why the most important thing about investing is always the art of execution.
