The investment trust Neil Woodford oversaw until last month has suffered another blow, after its fund administrator said it would reduce the valuation of one of its largest holdings.

In a November 4 update to investors in the Woodford Patient Capital Trust, Link Fund Solutions said it intends to reduce the valuation of Industrial Heat, the cold-fusion company that is the trust’s sixth-largest holding. The move will reduce the vehicle’s net asset value by approximately 5p per share.
