The benchmark Straits Times Index rose 0.78% to 2,969.73 points. Here are some stocks and factors to watch, according to Reuters.

Commodities firm Noble Group may be in focus after it said 2012 will continue to be challenging. Noble posted a 57% fall in fourth quarter net profit after being hit by volatile markets and poor processing margins.

City Developments, Southeast Asia’s second-largest property developer, posted a 32% fall in fourth quarter net profit to $163 million on Wednesday, hurt by lower rental income.

Palm oil firm Mewah International said its fourth quarter net profit plunged 65% to $12.7 million from a year ago, hurt by lower sales from its bulk segment and higher costs. Its earnings, however, doubled on a quarter-on-quarter basis.

Midas posted a 22% fall in its 2011 net profit to 187.4 million yuan ($37.1 million), hurt by lower contribution from its associate as fewer train cars were delivered its customers.
