Where the TLTW yield comes from
Current yield = average coupon ÷ average price. Pull to par = yield to maturity − current yield. The distribution yield is what was actually paid out over the past 12 months.

About the TLTW bond portfolio
iShares 20+ Year Treasury Bond BuyWrite… holds a portfolio of bonds. They yield 5.52% to maturity, have an average coupon of 3.67% and an average maturity of 24.7 years. With an effective duration of 15.34 years, a one-percentage-point rise in interest rates would lower the fund's price by about 15.3%, and a fall of the same size would raise it by about as much.
Because the bonds trade at an average of 74.69 per 100 of face value, part of the expected return comes from prices drifting back to par as they mature, adding roughly 0.61% a year. The current yield is 4.92%. Over the next 12 months, rates could rise by about 0.36 percentage points before the price drop would cancel out a year of yield. The worst 12-month return in the fund's price history was −14.4%, and the worst calendar year 2024 (−2.2%).
The fund reports 104.0% of assets in bonds and a small short cash position, typical for funds that buy mortgage-backed securities through “to be announced” (TBA) forward contracts, which are paid for later.
EODHD does not publish the individual bonds held, so this page uses the fund-level statistics; the full list of bonds is on the issuer's website.
