Troubleshooting
How Do I Report a Calculation That Looks Incorrect?
Include the S&P basket, symbol, displayed units, feed, session/time, and a cleared screenshot if available. The current app does not calculate official SPX, Nasdaq-100, or Dow values.
What problem does this solve?
A displayed weighted value appears inconsistent with another figure.
Quick answer
Record the unit, selected S&P basket, IVV weight reference, symbol, and timestamp before comparing with an official index value. The app estimates from up to 30 stocks.
Steps
- Identify whether the disputed number is a stock return, percentage-point contribution, S&P-point estimate, or Pts/$1 sensitivity.
- Check the IVV-based weight, previous-close reference, and whether the point scale is marked as estimated from SPY's prior close × 10.
- Verify the same interval, session, and feed on both screens.
- Send the displayed inputs and a cleared screenshot through Technical support.
What you should see
A calculation report with enough context to reproduce the estimate and compare like quantities.
