The following is a lightly edited transcript of a talk given by Dr. Brock at the Portfolio Construction Forum, held in Sydney, Australia, from August 21-23.  A video of this talk is available here.


”Outside the box” is not about being deliberately different; it’s about understanding how the new environment we live in requires that we act differently if we are going to gain our objectives and our goals.

Using backwards induction

I will start off with some basic principles to help people answer the question, “What do I do with my money?”  I’m going to talk as if it’s my money that we’re talking about.  That makes it more personal, but the rules are pretty general.

In thinking this way I’m going to be using a kind of logic that isn’t that familiar to most people. It’s known in mathematics and game theory as “backwards induction,” and it’s a very powerful way of straightening out or trying to make sense of things. It asks, “What are your final goals with your money? What is it that you want out of your money?”  Then, “What do you do to get it?”

It’s the reverse of saying that when you’re 70 years old, you should be 65% in bonds, 25% in stocks and the rest in cash.  A traditional rule like that comes out of thin air. There are times when that’s a very good allocation, there are times when it’s bad, but by working backwards from what I actually want – which is not about returns at all ironically – we can perhaps do a little bit better job.

This logic was also used by two quite famous people. One was the great model and fashion designer Coco Chanel, who got it right, as did Franco Modigliani, the MIT and Chicago professor who would receive a Nobel Prize for his work – for his efforts to understand “what do I do with my money over my lifetime?” and “why?”

This is just glorified common sense, like all good logic, but the analysis proceeds from first principles. It does not proceed from what is traditional or what other people are doing.

Coco Chanel famously said when she lost her lawsuit to retain the rights to Chanel No. 5, as I recall, that she had only one desire in life, and that was to remain in her suite of rooms at the Ritz Hotel in Paris. It was on the Place Vendome, where you can now rent her rooms – the Chanel suite – for I think around $25,000 a night. She wanted her living standards maintained.

Do you think when you’re 70 years old you give a damn about your quarterly performance? Up 4.9999%, down 9.6%, up 14.1% or down 3.5%? By the time you’re 40, 50 or 60, you’re so used to seeing these up and down returns – how your portfolio has done – that it really doesn’t have anything to do at all with what matters to you, which is not being thrown out of your suite at the Ritz, or in my case a wonderful house I happen to have on the coast of Massachusetts north of Boston. Chanel wanted to keep her rooms at the Ritz regardless of inflation, deflation, the stock market, this or that. I want to keep my house.

As Modigliani would say – it’s part of your life cycle objective or planning structure. Your goal when you’re 40 is very different from when you’re 65. Facing retirement, what you want is to maintain a living standard that permits you to survive.  Inflation or deflation will come one way or the other.  You need what we call a “robust” strategy to maintain a lifestyle.
