FOUR out of five hedge-fund managers had expected Britain to vote to remain in the European Union, according to a poll by Preqin, a data firm. But a handful saw Brexit coming and invested accordingly. They made hundreds of millions by betting against assets that were likely to suffer from an Out vote. Crispin Odey’s London-based fund, which manages around $10 billion and has had a terrible year, jumped nearly 15% on the day after the vote. That was thanks to short positions on the shares of a number of British firms (including Aberdeen, an asset manager, and Berkeley Group, a builder) and a big investment in gold. Others, such as Atlantic Investment Management, prospered by betting against sterling, which fell this week to its lowest value against the dollar since 1985.
