Spot rubber continued to rule unchanged on Wednesday. According to sources, the market activities were in an extremely low pace following a weak closing on the National Multi Commodity Exchange. Sheet rubber finished flat at Rs 157.50 a kg, according to traders. The grade increased to Rs 157.50 (157) a kg at Kottayam and Kochi as reported by the Rubber Board. The trend was partially mixed as ungraded rubber improved marginally on comparatively better demand.
