Pepper futures slipped for the six trading sessions on the back of reports of Vietnam easing the prices of new crops and arrivals of Indian crops in the local market. The NMCE pepper for the February delivery ended the day at Rs 51,067, down Rs 383 or 0.74% over Friday`s close. Pepper futures are expected to extend the losses on profit taking and reports of flow of arrivals from India and Vietnam`s plan to sell at lower rates.
