Cash flow matching vs Multiple liability immunization indicate, matching, liability, understand

John10

Please assist, I don't get the CFAI books anymore.

Question 13 of reading 28. The answers indicate that Cash flow matching has generally less risk than multiple liability immunization. When I read the text on page 44, first paragraph of 4.2.1. I understand that minimum immunization risk approach is better than cash flow matching.

Where do I go wrong?
Thanks for your help!

cash flow matching is "set it and forget it"

immunization you must monitor and rebalance constantly, making it more risky

cash flow matching might have less risk "once set up", but that shouldn't be the only consideration. Needs to be costs effective as well. haven't read the text though.

Cash flow matching has less reinvestment risk

Thanks for this. It's this sentence that creates the confusion: "Most cases cash flow matching will be technically inferior to immunization".

Unless you know with absolute certainty the exact dates of cash flow liability requirement , it would be hard to match the asset-liability flows to leave nothing on the table at all times.

With the focus on keeping the cash available when it is going to be required to meet the spnding requirement, it would be almost impossible to plan ahead for the longer term flows. Hence it would be technically inferior to immuniztion . Keeping cash on hand would lower the net rate of return and lower the duration unnecessarily.

Combo or horizon matching attempts to match cash flow only in the near term when flows are known more precisely , and immunization for longer terms , when the exact opposite it true

Plausible story, now I understand. Thanks janakisri!

I love this forum

is cash flow matching inferior only to multiple liab immunization or to both multiple and classic immunization?? the text doesnt state this clearly, but it is my understanding that for a single future cash flow goal, cash flow matching is superior over classic immunization, but when you have multiple future cash flows, multiple liab immunization is superior.
