Inventories can support gross domestic product (GDP) growth when the pace of accumulation accelerates, but rising stocks can reflect either preparation for stronger sales or unsold goods. Sales data and inflation-adjusted quarterly figures are needed to judge the impact. On their own, these readings offer limited direction for Federal Reserve policy, Treasury yields or the dollar.What this report measures: Advance inventory estimates track the value of goods held by wholesalers and retailers at month-end. These preliminary figures are subject to revision and are not adjusted for inflation. Traders monitor inventories for clues about demand, business activity and their contribution to GDP.
