TLT is an ETF of US Treasury bonds with more than 20 years remaining to maturity. It aims to track a long-term Treasury index and holds roughly 50 bonds. Its price is particularly sensitive to changes in long-term interest rates.
History and development
TLT began on July 22, 2002, focusing on long-dated US Treasuries rather than short-term debt or the entire bond market. Its long-maturity portfolio has a distinct interest-rate sensitivity. The ETF's bond-price exposure is different from a series reporting the yield on ten-year Treasuries.

Comparing charts on this board
Pair TLT with US thirty- and ten-year yields to read bond prices against rates. Rising yields with falling TLT, and falling yields with rising TLT, provide the basic price-yield lens. BND adds a broader bond-market comparison.
Add the S&P 500 to distinguish Treasury buying during equity weakness from joint stock-and-bond selling. These patterns guide investigation toward growth concerns or rate and inflation news. Separate daily prices from distribution-inclusive performance.
