How TLT selects and weights its holdings
Providing exposure to long-term government debt, the iShares 20+ Year Treasury Bond ETF aims to replicate the performance of an index. This benchmark index is comprised exclusively of U.S. Treasury securities with maturities extending beyond two decades.
Today that leaves 47 positions, with the largest at 4.5% and the top 10 at 41% of the fund. Those weights move with share prices and reset whenever the fund rebalances, so the table above changes over time.
