Sir Chris Hohn may have just been through a UK record £338 million divorce, but his hedge fund group is still motoring along.

The $8.6 billion TCI Master Fund is up over 6% net of fees to the end of September 2014, according to a person familiar with the fund. Performance since the end of September has also been "strong", the person added. In comparison, the HFRI Event-Driven Activist Index is up just 0.3% year to date.
