LDRT is a fund of funds designed to track the BlackRock iBonds 1-5 Year Treasury Ladder Index. The index holds iShares iBonds Treasury ETFs, each targeting U.S. Treasuries across five consecutive maturities (1–5 years). Annually rebalanced on the last business day in June, the strategy removes the nearest-maturing ETF and adds a new 5-year ETF, maintaining a rolling exposure to Treasury bonds. Constituents are equally weighted, though price fluctuations may cause temporary drift, with weights reset during the next rebalance. This ladder structure aims to diversify interest rate risk while optimizing exposure to U.S. Treasury markets. The Fund invests primarily in these ETFs, cash, and cash equivalents, including BlackRock-affiliated money market funds. Its design aligns with the Underlying Index's methodology, ensuring disciplined rebalancing and risk management.
