How to read the market — inventory signals, timing, and the metrics that actually move profit.
Most Amazon research tools show you what a product did last month: its price history, its sales rank, its margin today. These guides are about the other half of the picture, the inventory sitting in the market right now and what it says about the next few weeks.
Each guide takes one question a wholesale seller actually asks, such as when to skip a product, how many days of stock the market has left, or why a rank chart is a poor guide to timing. They explain the signal, show how to check it yourself with free tools, and say plainly where a signal can mislead you.
Start with the guide on checking a product before you buy if you are new to wholesale. If you already source every week, start with Days of Cover and seller count, the two signals every other guide builds on.
