Sector caveat
Use full-year FCF. Quarterly FCF for Walmart, Target, or Costco is dominated by the inventory cycle, not by structural change.
Working-capital normalisation
Damodaran's working-capital dataset[Damodaran WC]publishes sector medians for receivables, inventory, and payables days. Normalise ΔNWC to those medians before judging FCF.
Q4 FCF spike
Q4 produces a cash inflow as inventory converts to sales and as accounts payable peak. Reading the Q4 spike as a structural improvement is the most common retail-analyst error. ASC 230[ASC 230]does not require seasonality disclosure, so the analyst must do this work.
