Quality Minus Junk
Long a composite of profitable, growing, safe, well-managed names and short the junk — AQR’s QMJ recipe.
Definition
Quality Minus Junk refers to managed names and short the junk — AQR’s QMJ recipe. Keep that definition fixed when comparing series, managers, or regimes — renaming the same tape does not create a new signal.
Why it matters
It is a named object desks use to frame risk, positioning, or process. When managed names and short the junk — AQR’s QMJ recipe shifts, related hedges, limits, and narratives usually need an explicit update rather than a quiet assumption.
Case
Suppose a desk is positioned for the opposite of what quality minus junk is saying. If managed names and short the junk — AQR’s QMJ recipe moves against that book, the first question is not “is the story clever?” but whether size, hedges, and stop logic still match the observation.
How to read it
Keep the definition fixed, then challenge it with cross-checks before sizing. Prefer a short written null hypothesis for Quality Minus Junk: what would falsify the current reading in the next window?
