SIA Engineering on Friday said it is not aware of any information not previously announced that might have explained the unusual trading activity in its shares during the day. Shares in the aircraft maintenance, repair and overhaul (MRO) services firm surged 20 Singapore cents or 9.9 per cent to close at S$2.22 on Friday, on volume of 2.87 million.
