⚠ Eight Percent of Revenue Cannot Offset Ninety-TwoModerate threat
BlackRock (BLK) — threat to the moat
Real diversification, at a scale that cannot offset a quarter lost across a $13 trillion book.
The argument for the technology business as a stabiliser runs into arithmetic. It is roughly 8% of revenue1. In a year when equity markets fall a quarter, BlackRock's base fees fall with them across a $13 trillion long-term book, and $2 billion of software revenue that holds flat offsets a small fraction of the shortfall.
What the technology business genuinely provides is a floor under the growth rate and a reason for the shares to be valued as something other than a levered equity market position. Those are worth having. They are not the same thing as counter-cyclicality, and it would be a mistake to treat the two as interchangeable.
There is a second-order problem in a downturn as well. Aladdin's clients are financial institutions whose own revenue is falling in the same episode, and one of the reliable ways a cost-cutting asset manager finds savings is by trimming vendor contracts and deferring module expansions. Contracted revenue is protected at renewal; expansion is not, and expansion is where the growth comes from.
The thing to watch through the next drawdown is annual contract value growth rather than revenue, which lags. If ACV growth holds in the low teens through a bad market, the software business is what it appears to be. If it halves, it is a cyclical business with a subscription invoice.
