AIM - LOSERS
----------
Burford Capital Ltd, down 7.1% at 787.64p, 12-month range 518.29p-969.50p. The litigation finance provider says its commitments and deployments reached "record-breaking levels" in the first half of 2021, but expects a profit fall. Burford saw "robust" levels of new business during the six months to June 30. It made new commitments of over USD500 million, a company best, four times higher than a year earlier. In addition, it deployed USD399 million, more than treble year-on-year. The company posted realised gains of USD77 million during the half. However, it cautioned that 43% of matters in its portfolio have faced Covid-19-related delays. Some court dates have been delayed and the virus has also meant slower settlement activity.
