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 (0.25%) 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.

CBTO risks and drawbacks

Payments are annual, so cash flow is lumpy versus a monthly fund. Total return has trailed SPY over the available window. The deepest 1-year drawdown on record here is 20.9%.

Who may consider CBTO — and who may not

It is a weaker fit for investors who need monthly cash flow (CBTO pays annual); investors whose main goal is matching SPY total return. This is educational context, not a recommendation to buy or sell.
