"However, a rise in the oil price above US$120 per barrel would help boost the index, especially energy shares," Krungsri Securities said.
It recommends the purchase of the following as an investment strategy:
• PTT, TOP, SPRC, BCP and BANPU will benefit from the rising price of oil, coal and gross refining margin.

• BDMS, INTUCH, ADVANC and DTAC, which are defensive stocks.
