Odey Asset Management, Marshall Wace and Polar Capital are among the fund managers likely to have made big paper gains on the slump in Metro Bank shares on January 23, following a disappointing trading update from the challenger bank.

With a short position equivalent to 2.7% of Metro’s shares, Odey has the largest bet against the company, according to the register of short positions maintained by the Financial Conduct Authority, the UK markets regulator, so it stands to profit most from the 30% price plunge.
