Kuala Lumpur Kepong Bhd, a Malaysian plantation company, dropped the most in almost two years after the stock was downgraded at HwangDBS Vickers Research Sdn Bhd to reflect weaker earnings prospects.

Its shares lost 4 percent to RM20.36 at 10:17 a.m. local time, set for the steepest decline since Oct. 6, 2009.

HwangDBS downgraded the stock to "hold" from "buy" and reduced its share estimate to RM22.60 from RM25.35, it said in a report today. -- Bloomberg
