Thailand's big-cap stocks declined today, led by PTT on concern of possible energy reforms.
In the morning session, PTT share price dropped by Bt8 or 2.63 per cent, to Bt296.
The Stock Exchange of Thailand composite index edged down by 7.49 points or 0.54 per cent, to 1,389.35 points.
Investors were cautious about possible reforms in the energy sector and potential changes to the board of state-controlled PTT.
Over last weekend, a message was circulated in social media, saying that the National Centre for Peace and Order (NCPO) would intervene PTT and all Thais can wait for a cut in energy prices.
Foreign investors had been net-sellers of Thai shares in the past week after the military power seizure, boosting their month-to-date net sell to Bt22.7 billion.
