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.
