Software provider Misys yesterday issued an upbeat trading statement that demand for its core banking and securities products was returning to normal following 11 September.
The company, which also supplies computer systems for insurance brokers, said there was evidence that its market was stabilising, that few projects were being cancelled and that the banking industry remained resilient.
Misys shares gained 16p, or 5.14%, to close at 327p yesterday.
Meanwhile, disaster recovery company Guardian IT has lowered full year sales forecasts, citing deteriorating market conditions.
The company said it had not benefited from increased awareness of the need for contingency plans following 11 September.
Chief Executive Peter McLean said: "We are seeing two conflicting scenarios. Through increased awareness, our prospect pipeline is at the highest level it has ever been, but against that sales cycles are lengthening and that's partly because of the caution of some customers in the face of economic difficulty."
Guardian IT shares plummeted 265p, or just over 60%, to 175p yesterday.
