Institutions that build the infrastructure first ( or partner with @ArrelTechnology 馃槈) tend to spend more time launching and far less time rebuilding.
Execution errors in portfolio management are rarely dramatic. They are usually small. A slightly off-target allocation, a delayed rebalance, a missed account.
It provides systematic rebalancing logic. Every account evaluated against the same parameters, on the same schedule. Consistency becomes structural rather than dependent on individual diligence.
The answer is not better spreadsheets. It is portfolio operations infrastructure where the process is embedded in the system - not imposed on top of it.
