Golden Agri-Resources outperformed a jittery Singapore stock market on Monday, heading for its biggest daily gain in six months after well-received earnings.

Shares of the palm oil plantation firm jumped 5.4% to their three-month high of $0.59, with 98.5 million shares changing hands as of 11:54 a.m., more than three times the 30-day average daily volume.

Golden Agri reported a 129% surge in fourth-quarter net profit on Friday, helped by a better sales performance in China.

OCBC Investment Research maintained its “hold” rating on Golden Agri, increasing its fair value to $0.52 from $0.50 and its 2014 revenue estimate by 2-3%.

“Going forward, management remains largely positive about its prospects,” OCBC said in a research note.

The benchmark Straits Times Index opened the week with a lull, declining nearly 0.8% to 3,085.8 as of 11:52 a.m., in line with other Asian markets, as escalating tensions between Russia and the West caused jitters. MSCI’s broadest index of Asia-Pacific shares outside Japan fell 0.8%.

Figures showing Chinese manufacturing activity fell in February added to the gloomy sentiment. The final Markit/HSBC manufacturing Purchasing Managers’ Index (PMI) fell to a seven-month low of 48.5 in February, reinforcing concerns of a slowdown in the world’s second largest economy.

Noble Group and Olam International were the worst performers, down 3.8% and 2.8%, respectively. Shares of Olam International were headed for their biggest daily decline in more than five weeks.
