How Dividend Vision calculates yield and returns

Distribution rate (4.37%) 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 (4.24%) 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. Fund total return uses split-adjusted close with distributions reinvested from the first stored bar on or after inception through the latest bar, compared with the same window on the benchmark. That is what the fund did, not your personal gain/loss. Figures below use Dividend Vision data as of August 19, 2026.

Who may consider VMBS — and who may not

VMBS may suit someone looking for low-cost broad dividend exposure, a high Distribution Safety Score, moderate current income with a quality tilt. It is a weaker fit for investors hunting double-digit covered-call yields; investors whose main goal is matching SPY total return. This is educational context, not a recommendation to buy or sell.
