Scan the whole catalog for the SKUs that moved the most this period - up and down - and decompose each move into its cause: traffic, conversion, price, or buy-box. Ranked by the size of the swing in money, with a data-completeness guard on both windows so a lagging or partial week doesn't read as a fake collapse or a fake boom. Live from DataDoe, read-only. Use for "what changed", "biggest movers", "why did sales drop", "what's up this week", "sales down", "which products dropped", "what moved", or "week over week".
