Pair ratio · BJ ÷ COSTRelative value, rich or cheap vs their own history

The price ratio BJ ÷ COST with its 1Y mean and ±1σ / ±2σ bands; the z-score is how far the ratio sits from its average. A stretched reading flags one stock as rich vs the other relative to their history, but mean-reversion isn't guaranteed (a durable re-rating from better growth or margins can keep the ratio elevated). Research tooling, not advice.
