Sector rotation shifts weight toward the parts of the market expected to lead and away from those expected to lag. It’s a higher-level strategy than single-name trading, and an agent can track the signals across sectors continuously. The risk is that "continuously" turns into "constantly trading." Here’s how it works and how to bound it.
How it works
The agent groups holdings by sector, reads signals (relative strength, breadth, macro inputs), and rotates allocation toward favored sectors. You express it as target sector weights plus the conditions that trigger a shift.
Where it goes wrong
- Frantic rotation. React to every wiggle in the signal and the agent rotates too often — costs pile up and you’re always a step behind.
- Hidden concentration. Rotating "into tech" can quietly become a few names doing all the work, far more concentrated than you intended.
- Signal manipulation. Macro and news inputs drive rotation, so planted or misread inputs can push the agent the wrong way.
The guardrails that matter here
- Allowlist — constrain the universe to the sectors/ETFs you actually want it rotating among. See spending and trade limits.
- Per-ticker concentration cap — so "overweight a sector" never becomes "all-in on one name."
- Approval gate — require sign-off on large rotations.
- Rotation cadence — instruct the agent to rotate on a defined schedule or signal threshold, not continuously.
