Cross-sectional
A strategy that ranks instruments against one another at a point in time and takes offsetting long and short positions across the ranking, rather than comparing an instrument to its own history.
Why it matters
The defining property is that the market's overall direction is largely neutralized — you are expressing a view about relative ordering, not level. That makes the return profile fundamentally different from time-series strategies even when the signal is identical: cross-sectional momentum and time-series momentum share a name and behave differently in a crash.
What it is not
These are routinely confused with Cross-sectional. The distinctions are not pedantic — each one has consequences for how a system is governed.
Time-series compares an instrument to its own past. Cross-sectional compares instruments to each other. Same signal, different exposure to market direction.
Market neutral is a constructed property. Cross-sectional construction tends toward it without guaranteeing it.
