How we compare these
Every comparison on this page is computed from current public data, not written by hand. Yield comes from the most recent dividend distribution annualized over current price. Safety scores combine yield zone, payout ratio, trend vs 5-year average, instrument type, and size — see our methodology for the exact formula. Tax-efficiency flags identify covered-call ETFs, REITs, and mREITs which distribute primarily as ordinary income.
This is educational, not investment advice. Scores reflect a snapshot of public data on the "as of" dates shown on each ticker's safety page. Verify on the issuer's investor relations page or your brokerage before making decisions.
