Marketing and advertising agency Adventis said trading to date has been 'generally' in line with expectations, adding that 2010 remains challenging.The healthcare business continues to perform well, but there is some evidence of a slowdown affecting the sector, the group said.The technology and telecoms market has improved, while the media planning and buying businesses remain profitable. Activity in the property sector remains at a low level, though the commercial property market is demonstrating some evidence of recovery."The board is actively considering several opportunities which would support the programme of growth," said the group."The economic and political climate will ensure that 2010 remains challenging. We believe that the group remains well placed to continue to trade profitably and to take advantage of the opportunities that will be created."
