Siam Cement stocks rose 2.8 per cent to THB254, having hit THB255, its highest since November 1, 2007, on expectations of strong first-quarter earnings due to higher petrochemical spreads and a recovery in its paper earnings.

Broker Kim Eng Securities said it expected a 16-25 per cent increase in net profit for the January-March quarter to THB6.0-6.5bn and targeted a share price of THB280bn.
