What you get
This outcome tracks who holds each CMBS CUSIP, including reporting funds, position sizes, and concentration. Notifications show what changed and include source evidence for review.
- Current Ownership View
See who holds each CUSIP right now.
For each CMBS CUSIP, we maintain a current view of ownership: which funds hold it, their position sizes, and how concentrated the holdings are. This view updates as new disclosures come in.Define CUSIP scope - Change Notifications
Know when ownership shifts.
When new SEC Form N-PORT filings reveal ownership changes, such as a new holder, a position increase, or a concentration threshold crossed, you get a structured notification with timestamps and confidence indicators.Book discovery - Evidence records
Every notification links back to the source.
Each change notification includes an evidence record: the original SEC filings, disclosure dates, how we mapped the data, and what ownership looked like before.
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.Delivery
Notifications arrive via email, Slack, or webhook when relevant N-PORT filings become public. Each notification includes a link to the evidence record so you can see the source.Let me know when a new fund appears in the top holders for this CUSIP.
Notify me when ownership concentration crosses a threshold I set.
Keep track of who owns these CUSIPs and tell me when positions change.
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
Start with discovery in five steps.1
Choose the deliverable
Identify what you want delivered: ownership changes, concentration threshold alerts, or position change notifications for your CMBS CUSIP universe.2
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.3
Specify coverage
List the CMBS CUSIPs (up to 25 for evaluation), set position change thresholds, and enable concentration monitoring if needed.4
Pick a delivery channel
Choose email, Slack, or webhook for notifications. Each delivery includes a link to the evidence record and confidence flags.5
Qualify the outcome
Provide the context, owner, and source material. We will qualify fit and, if there is a real outcome, schedule a two-hour working session.Common questions
What is CMBS CUSIP ownership state?
CMBS CUSIP ownership state is a maintained record of who currently holds a CMBS CUSIP based on publicly disclosed SEC Form N-PORT fund holdings, including reporting funds, position values, concentration metrics, and disclosure coverage.What CMBS ownership changes will I receive?
You receive configured ownership changes such as NEW_HOLDER_ADDED, HOLDER_EXITED, POSITION_INCREASED_OVER_THRESHOLD, POSITION_DECREASED_OVER_THRESHOLD, TOP_HOLDERS_CHANGED, and CONCENTRATION_THRESHOLD_BREACHED. The exact set depends on your thresholds and configuration.What evidence is included with each ownership change?
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 scope defines detection and delivery targets before launch.What happens after the evaluation?
We review coverage, latency, evidence completeness, and delivery reliability with you. If it is a fit, we propose a production monitoring plan with defined delivery targets 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 source context 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.
