Frequently Asked Questions
What's the difference between TLT and BND?
TLT holds only long-term Treasury bonds (20+ year maturity). BND holds the entire aggregate bond market including corporates, MBS, and various maturities. TLT has much higher interest rate sensitivity (duration ~17 vs ~6).
Is TLT good for trading?
Yes, TLT is actively traded due to its high interest rate sensitivity and liquid options market. Traders use TLT to express views on rate cuts, hedge equity risk, or generate income through covered calls.
Why did TLT fall so much in 2022?
TLT fell ~30% in 2022 because the Fed raised rates from 0% to over 5%. With a 17-year duration, a 5% rate increase causes approximately 85% price decline in theory (though partly offset by yield). Long bonds are extremely rate-sensitive.
