MAYBANK Kim Eng's outlook for Singapore's aviation services firms remains "positive", with SATS as its top pick, it said in its latest industry note on Monday. The brokerage said the firms performed well despite facing headwinds from weak visitor arrivals for the first half of 2019, trade war related shrinking of air cargo volume, and the Hong Kong unrest. Maybank Kim Eng made "buy" calls on SATS, Singapore Technologies Engineering (ST Engineering) and SIA Engineering, with a discounted cash flow-based target price of S$6.10, S$4.50, and S$3.00 respectively. Singapore's aviation traffic statistics for the first nine months of the year saw passenger arrivals at Changi Airport up just 2.1 per cent year on year due to a poor first half. This was after Chinese arrivals fell due to the slowing economy and yuan decline.
