Ask us

How much would SUB fall if rates rose?

With a duration of 2.0 years, an immediate one-point rise in rates would take about 2.0% off its price. An equal fall would add about the same.

What is SUB's yield?

On August 31, 2026, according to its filing, the bonds it holds had a yield to maturity (YTM) of 2.99% a year, before the fund's costs. That is not the distribution the ETF pays, and it moves every day with prices.

How did SUB do in 2022?

In 2022 SUB returned -2.2% in total, as the fund reports it.

Is this SUB's dividend yield?

No. The yield to maturity shown here is what the bonds the fund holds would earn a year if held to maturity, at the prices on the filing date. The dividend yield measures what the ETF paid over the last 12 months against its price, and it lags, because it depends on the coupons of bonds bought earlier. The SEC yield the issuer publishes is a standardised 30-day figure after costs, and usually lands close to the yield to maturity, a little below. When rates have risen, the dividend yield is usually lower than the other two.
