The NCDEX Dhaanya index rose 9.82 points to 3205.08 points, largely due to gains in chana and castor seed contracts. A fall in guar seed contracts restricted the rise in index. Dhaanya is a value-weighted index, computed real-time using the near-month prices of 10 most liquid commodity futures. The components of the index and their weights are re-balanced every quarter. Currently, chana and guar seed carry a weight of 20% each, soybean 16%, and mustard seed 15%, and cottonseed oilcake 8%. Castor seed, coriander, barley, jeera, and turmeric are the other components of the index.
