Does 'Because a reduction in the I/S ratio means that changes in sales will be matched by a smaller change in inventories, a lower ratio also implies lower inventory volatility.' provide a contradiction to the established premise 'A lower I/S ratio results in lower inventory volatility and changes in sales will result in smaller changes in inventories.'
Because a reduction in the I/S ratio means that changes in sales will be matched by a smaller change in inventories, a lower ratio also implies lower inventory volatility.###A lower I/S ratio results in lower inventory volatility and changes in sales will result in smaller changes in inventories.
