Guar gum prices tumbled by Rs 198 to Rs 9,440 per quintal in futures trade Friday as investors indulged in offloading their positions amid muted export demand.
Marketmen said cutting down of the holdings by investors, weak export demand for oil drilling industries and profit-booking led to fall in guar gum prices.
At the National Commodity and Derivatives Exchange counter, guar gum for delivery in far-month November contracts crashed by Rs 198, or 2.05 per cent, to Rs 9,440 per quintal, with an open interest of 6,620 lots.
