How to validate investment data integrity with your AI

Connect your portfolio data once. Your AI handles the math to catch errors before they hit your risk models.

Short answer

How do I check if my portfolio weights are correct?

Your AI runs a mathematical check on your asset weights and total values to find discrepancies. It flags any rounding errors or sum mismatches so your risk models stay accurate. You'll see exactly where the math breaks down.

Where errors land.

The outcomes of a data check.

The AI identifies specific mathematical failures and organizes them for you.

ERRORS

Weight mismatches found

The AI identifies where asset weights don't sum to 100%. You get a list of specific assets that are causing the drift.

VALUES

Value discrepancies flagged

It catches instances where individual position values don't align with the total portfolio value. This prevents skewed risk calculations.

LOGS

Audit trail generated

The AI creates a record of the validation check. You can review the math used to verify each position.

HUMAN

Manual fixes required

The AI identifies the broken data but won't change your source files. You decide which values to correct in your system.

The workflow

What your AI does when the data arrives.

The AI acts as a mathematical gatekeeper for your portfolio data.

  1. Data ingestion

    Your AI reads your current portfolio holdings and their assigned weights.

    validate_portfolio_data

  2. Summation check

    The AI calculates the total of all weights to ensure they equal exactly 1.0.

    validate_portfolio_data

  3. Weight vs Value check

    It cross-references the weight of each position against its dollar value and the total portfolio value.

    validate_portfolio_data

  4. Error reporting

    The AI isolates the specific rows or assets where the math fails.

FAQ

How this task behaves

  • 01

    Will the AI fix the errors in my spreadsheet?

    No. The AI only identifies and reports mathematical discrepancies. You must manually update your source data.

  • 02

    Can the AI run risk models directly?

    No. This specific tool is for validating data integrity. It ensures your data is ready for risk models, but it doesn't run the models itself.

  • 03

    Does it check for missing data?

    Yes. It flags any positions that are missing weights or values during the validation process.

  • 04

    Can I use this with any spreadsheet?

    Yes, as long as your AI client can read the file and the data is structured with weights and values.

  • 05

    How does it handle rounding errors?

    The AI identifies when rounding causes the total weight to deviate from 100%.
