0239 GMT - Palm oil rises in early Asian trading, driven by overnight gains in soybean oil on the Chicago Board of Trade. Overall, the market remains constructive, although profit-taking could emerge ahead of the U.S. Department of Agriculture's World Agricultural Supply and Demand Estimates report, which could shift CPO futures expectations through changes in forecasts of global vegetable-oil supply and demand, AmInvestment Bank says. It expects palm-oil prices to face resistance at 4,930 ringgit a ton and support at 4,846 ringgit a ton. The Bursa Malaysia Derivatives contract for November delivery is up 18 ringgit at 4,903 ringgit a ton.
