The rate of turnover is the number of times the stock is turned over during a given period. In other words, it measures how quickly a company is selling and replacing its inventory. This is an important metric for businesses as it helps them to manage their inventory levels, track sales trends, and optimize their operations. A high rate of turnover generally indicates that a company is efficiently selling its products and replenishing its stock, while a low rate of turnover may suggest that a company is holding onto inventory for too long and may need to adjust its sales and marketing strategies.
