Thai Beverage Pcl has jumped 37 percent to a record in 2016, benefiting from rising consumption in Thailand, where stimulus and low interest rates have driven the benchmark index to the highest level in almost a year. Singapore’s equities market, by contrast, is a laggard in Southeast Asia, suffering from lackluster growth at banks, developers and oil-rig builders. Thai Beverage’s return this year is almost triple that for the second-best stock in the Straits Times Index.
