How Dividend Vision calculates yield and returns

Distribution rate (the posted rate) is the latest regular payout annualized by the fund's stated frequency, divided by the last close. Issuers often publish this as “Distribution Rate” on the fact sheet. Trailing-12-month yield is the sum of distributions paid in the last 12 months, split-adjusted, divided by the last close. It lags a recent raise or cut. We show a 30-day SEC yield when the fund publishes one. Schwab and other issuers may report a TTM distribution yield or SEC yield on a different date — all can be valid; they are not interchangeable. 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. Figures below use Dividend Vision data as of September 3, 2026.

Who may consider MARS — and who may not
