What you get

This outcome tracks who holds each CMBS CUSIP—reporting funds, position sizes, and concentration—and notifies you when ownership changes. Every notification includes the underlying evidence so you can verify and revisit it later.

How it works

Straightforward process, reliable results. We ingest public disclosures, track changes, and notify you—with clear documentation at every step.

Data source

We pull from SEC Form N-PORT filings (public portions) for your selected CMBS CUSIPs. Each filing is timestamped when we receive it, and CUSIPs are normalized using DealCharts.org mappings.

Tracking ownership

For each CUSIP, we maintain who holds it, position sizes, and concentration metrics. When a new disclosure shows meaningful changes, we update the record and send you a notification.

01"Let me know when a new fund appears in the top holders for this CUSIP."

02"Notify me when ownership concentration crosses a threshold I set."

03"Keep track of who owns these CUSIPs and tell me when positions change."

04"Show me what ownership looked like on a specific date, with the underlying disclosures."

Clear notifications. Traceable evidence. No guesswork.

Try it with your CUSIPs

Get started with a free workshop in five steps.

Choose the deliverable

Identify what you want delivered—ownership state transitions, concentration thresholds, or position change notifications for your CMBS CUSIP universe.

Set the schedule or trigger

Determine when outcomes should be delivered: immediately on N-PORT publication, on a periodic schedule, or both. Specify freshness and latency requirements.

Specify coverage

List the CMBS CUSIPs (up to 25 for evaluation), set position change thresholds, and enable concentration monitoring if needed.

Pick a delivery channel

Choose email, Slack, or webhook for notifications. Each delivery includes a link to the provenance record and confidence flags.

Authorize the outcome

Provide your name, email, and company. We'll schedule a free 60-minute workshop to run this outcome on your data.

Common questions

What do you mean by "ownership state"?

Ownership state is a maintained record of who currently holds a CMBS CUSIP based on publicly disclosed fund holdings in SEC Form N-PORT—reporting funds, position values, concentration metrics, and disclosure coverage—timestamped and versioned.

What transitions will I receive?

You'll receive deterministic ownership changes such as NEW_HOLDER_ADDED, HOLDER_EXITED, POSITION_INCREASED_OVER_THRESHOLD, POSITION_DECREASED_OVER_THRESHOLD, TOP_HOLDERS_CHANGED, and CONCENTRATION_THRESHOLD_BREACHED (exact set depends on your thresholds and configuration).

What's included in the provenance record?

Each transition includes source N-PORT filing links, accession numbers, disclosure timestamps, mapping and normalization steps, checksums, known limitations, and a delivery log—so the ownership state can be reconstructed later.

How fast are transitions delivered?

During the evaluation we target best-effort delivery and include latency metadata in every transition. Production plans add explicit SLA commitments for detection and delivery.

What happens after the evaluation?

We review coverage, latency, evidence completeness, and delivery reliability with you. If it's a fit, we propose a production monitoring plan with formal SLAs and expanded scope options.

What is SEC Form N-PORT?

Form N-PORT is a monthly portfolio holdings report filed by registered investment companies. The public portion discloses fund-level holdings, including CMBS positions, with a delay (typically 60 days after quarter end).

Why teams use this

Most systems just tell you something changed. This outcome shows you who owns what right now—and keeps a record you can go back to when questions come up later.

Works with your systems

Notifications include structured data and stable identifiers, so your tools and workflows can consume them reliably.

One view for the whole team

Investment, risk, and compliance teams can reference the same ownership record, with clear provenance for each data point.

History you can revisit

Every change is logged with evidence. Months later, you can still see what changed, when, and what disclosures supported it.

Built for:

Hedge Funds & Asset Managers

Credit & Structured Finance

Capital Markets & Trading

Risk Management & Compliance

Enterprise Analytics Platforms

Always know who owns what—with the disclosures to back it up.
