The stock is helping lift the oil equipment services and distribution sector higher today. It has been helped by comments from the broker FinnCap, which said yesterday: 'We believe the share price has over-reacted to interim results, which pointed to margin weakness. Indeed, the analysts meeting uncovered that the group is already seeing a pick up in its higher margined specialist services so that gross margins will recover in H2 [the second half].'
