How an Asset Manager Automated Portfolio Rebalancing

• Company: Multi-strategy asset manager (anonymized)
• Industry: Asset management
• Team Size: 40 investment and operations professionals
• Headquarters: United States
• Use case: Automated model rebalancing and portfolio operations

The Challenge

The asset manager ran multiple model portfolios across taxable and non-taxable accounts. Rebalancing required downloading holdings, checking drift, applying model changes, reviewing constraints, estimating costs, and assembling trade lists by hand.

The process worked, but it was slow and fragile. Every rebalance depended on analyst time, spreadsheet controls, and a final manual check to catch exceptions before trade handoff.

What Celestice Changed

Celestice automated the drift detection and proposal-generation layer. The platform compared each account against its model, identified meaningful drift, checked restrictions and cash needs, estimated turnover and transaction costs, and produced a proposed trade list for review.

High-impact trades still required approval. The difference was that portfolio managers reviewed a complete evidence packet instead of building one from scratch.

Why It Mattered

The team reduced operational drag while improving oversight. Rebalance proposals became faster to produce, easier to inspect, and more consistent across strategies and accounts.

Client perspective

The rebalance process used to absorb the better part of two days. Celestice made the trade list reviewable in hours, with every constraint and exception visible before approval.
