Sugar stocks fell sharply on Friday after the government imposed a 20 per cent duty on the raw, white variety's export.
Shares of Ugar Sugar Works, KCP Sugar & Industries, Oudh Sugar Mills and Rajshree Sugars & Chemicals fell 10 per cent each. Most of these had rallied sharply in the past month with a rise in sugar prices.
The 20 per cent duty is aimed at boosting domestic supply and keeping prices, now Rs 40 a kg, under check. Globally, its price has risen 50 per cent in six months, due to a delayed harvest in Brazil, the world's largest producer (India is second).
