The test asks one question of every business unit: does it feed the others and do the others feed it? Units that pass stay; units that only coexist are extraneous and get sold, regardless of standalone profitability. Dimon's reference model is a small community bank that knows the customer's business account, consumer account and trust affairs and cross-serves all three from a single relationship, the strategy is that model plus global investment banking, and nothing else. The second-order benefit is risk legibility: once a portfolio contains businesses management cannot underwrite, exposure hides in the units nobody understands. The discipline compounds because it is coupled with continuous reinvestment into people, branches and technology rather than into new unrelated verticals.
Origin
Extracted from Acquired. Dimon contrasts it with Sandy Weill's Citigroup, which accumulated consumer finance, life insurance, property casualty and even truck leasing before divesting all of them.
Core principles
- 01A portfolio is legitimate only where the businesses feed each other.
- 02Hobbies are businesses kept for reasons other than fit.
- 03If leadership cannot understand a unit's risk, that is a divestment signal.
- 04Strategy that survives the cycle beats strategy that flips with the market.
- 05The model to copy may be much smaller than you, scale is the addition, not the idea.
How to run it
- 1
Define the reference model
Identify the smallest version of your business that already works coherently (for Dimon, a community bank that knows a customer's business, consumer and trust needs at once) and treat everything else as an addition to be justified.
Pro tip Small operators often have the strategy right and only lack scale. Copy the coherence, add the scale.
- 2
Map the feeds
For every unit, write down which other units send it business and which it sends business to. Middle-market clients using investment banking products, consumer clients using FX, and so on.
Watch out A theoretical synergy nobody has ever executed is not a feed.
- 3
Mark the extraneous units
Any unit with no feed in either direction is a hobby. Its standalone profitability is not a defence.
- 4
Apply the risk-legibility check
Ask whether senior leadership can genuinely explain the risk in each remaining unit. Unreadable risk in a diversified portfolio is a second divestment trigger.
Watch out Once the portfolio is wide enough, nobody can hold all the risks in their head, which is how conglomerates surprise themselves.
- 5
Divest, do not optimise
Sell or wind down the extraneous set rather than assigning better management to it. Improving a business that does not fit still consumes attention and capital.
- 6
Hold the strategy through the cycle
Do not flip the portfolio in response to market moves. A strategy that survives the test of time is itself a component of a fortress balance sheet.
Pro tip Markets are like accordions: expect them to expand and contract without changing your portfolio thesis.
- 7
Reinvest continuously into the retained set
Direct the freed capital into the three durable investment lines (people, branches and technology) rather than into new unrelated businesses.
In the wild
Dimon describes Citigroup accumulating consumer finance, life insurance, property casualty and, via American General, truck leasing, businesses he says did not fit and that Citi eventually divested entirely. At JP Morgan the retained portfolio is deliberately interlocking: middle-market clients buy investment banking products, consumer clients use FX, and the commercial, consumer, card, wealth and investment banking units feed one another. Everything that did not fit a strategy was removed. Commercial banking branches subsequently opened across Europe on the same logic.
→ A portfolio where, in his words, all of the businesses feed each other and there is no extraneous.
Common mistakes
Keeping a profitable non-fit
Standalone profitability is the most common reason hobbies survive a portfolio review. The test is feed, not margin.
Counting hypothetical synergies as feeds
A cross-sell that exists in a deck but not in the revenue line is not a connection. Require evidence of actual flow between units.
Flipping the portfolio with the cycle
Reshaping the business set in response to market moves destroys the durability the test is meant to create, and makes the risk profile unreadable again.
Is it for you?
Best for
Leaders of multi-business or post-merger companies deciding what to keep.
Not ideal for
Single-product companies, and true holding companies whose thesis is deliberate non-correlation.
From the transcript
“So, all of our businesses feed each other. There's no extraneous. We got rid of everything that didn't fit a strategy.”
“I don't like hobbies.”
“once you get involved in these things, it's hard for people to understand the risk in each one of these businesses”
