BANGKOK, May 19 (Reuters) - Thailand's benchmark stock index was up 2.9 percent at 555.68, its highest since Oct. 6, at 0348 GMT on Tuesday, with big-cap energy shares leading the advancers.
However, the rise may be capped ahead of the release of U.S. housing starts after the close in Bangkok and the Bank of Thailand's review of interest rates on Wednesday, analysts said.
'Investors should be vigilant as regards drastic profit taking as a number of counters, like refinery and petrochemicals, already trade above fair values,' Broker KGI Securities said in a research note.
