1. 027It is March 2020 and your equity weight has fallen twelve points below target. Do you rebalance?RebalancingIntermediatesuperdayMulti-assetInstitutional asset management

   Say this

   Yes, because the policy says so, but in stages and with a liquidity check first. The whole value of having a written rebalancing rule is that it is executed in exactly this moment, when doing it feels worst.

   Then walk it

   1. First, the liquidity check. Can I raise cash for the equity purchase without selling the only liquid thing I own? In March 2020 investment grade bid-ask spreads widened enormously, so funding the trade by selling credit would have crystallised a big cost.
   2. So fund it in order of cheapest execution: cash buffer first, then equity futures to restore beta immediately, then rotate into physicals over days as spreads normalise. Futures are the right instrument precisely because cash equity impact is at its worst.
   3. Stage it. Move a third of the gap at a time against defined triggers rather than one block, which both reduces impact and is easier to defend to a committee if it falls another 10 percent.
   4. Check whether the target itself is still right. Rebalancing is not the same decision as revisiting the strategic allocation. If the client's circumstances changed, for example a pension sponsor whose covenant just deteriorated, then a lower equity target is legitimate. Otherwise drift is not information.
   5. Say the governance point: the reason committees fail this test is that rebalancing requires buying while the newspapers say the world is ending, so the rule has to be pre-agreed and the execution delegated. A rule that needs a fresh vote in a crisis is not a rule.
   6. The honest counterweight: if the drawdown has pushed the institution near a hard constraint, a regulatory capital floor or a funding trigger, then mechanically rebalancing into risk can be the wrong answer. Constraints override policy, and saying that shows you are not just reciting discipline.

   Where candidates lose it

   Answering 'yes, rebalance' with no mention of liquidity or execution. In a real crisis the constraint is not conviction, it is that the cheap side of the trade is illiquid. The strong answer names futures for the fast beta restoration and staged physical trading, and flags the one case where you would not rebalance, a hard constraint being near breach.

   Expect next

   • How would you fund the purchase?
   • What would make you not rebalance?
   • How do you stop the committee overriding the rule?
