Software group Micro Focus was on a downward slide after activist investor Elliott Management sold its stake in the company.

The New York-based hedge fund, run by billionaire Paul Singer, revealed it had built a 5.1 per cent position in April.

Rumours emerged that Elliott wanted Micro Focus to sell itself to a private equity firm, and the activist also suggested that it flog-off its Suse Linux arm, which creates computer operating systems for businesses.

Private equity house EQT bought Suse in July for £1.9billion. The unit had been one of the profitable parts of Micro Focus, and a particularly bright spot when the group revealed disappointing results in January and March.

But it seems that Elliott has decided to call it quits, as a regulatory filing yesterday showed it had reduced its holding in the £6billion company to below 5 per cent, possibly to zero. Micro Focus's shares fell back 3.3 per cent, or 47p, to 1383p in response.

The FTSE 100-listed software company has not had a good year. Its botched acquisition of HPE Software in 2017 has weighed heavily, and chief executive Chris Hsu quit in March when it emerged that the integration of HPE was a year behind schedule.

Over the year to date, Micro Focus's shares have sunk 44.4 per cent.
