Where do these valuation figures come from?
Yields and quality metrics are computed from the same SEC TTM figures as the financials page, against the live market cap. Historical bands reconstruct month-end market cap from split-adjusted closes and the share count in the units it was filed, then divide by those dollar totals. Nothing here is a third-party estimate.
