How Dividend Vision calculates yield and returns
Distribution rate (the posted rate) uses calculation basis unavailable. Issuer rates can use a different denominator and date, including ex-date NAV. Trailing-12-month yield is the sum of split-adjusted cash distributions with ex-dates in the last 12 months, divided by the published price. It lags a recent raise or cut. Total return uses split-adjusted close with distributions reinvested on the ex-dividend date (a modeling convention, not the cash-settlement date) from the first stored bar on or after inception through the latest bar, compared with the same window on the benchmark. That is the security's total return, not your personal gain/loss.
