How To Read It
- TLT is a bond-price ETF proxy, so it generally moves opposite long-term yields and is not itself a yield chart.
- Because the fund owns long-duration bonds, changes in inflation expectations, real yields, and term premium can drive large price swings.
- Pair it with the 10-year yield and full Treasury curve board to see which part of the rates backdrop is driving the move.
