TLT vs EDV: Long Treasuries vs Extended Duration STRIPS
Both TLT and EDV bet on long-term US Treasury bonds. EDV is cheaper and more volatile, and its longer duration amplifies both gains and losses when rates move.
TLT (iShares 20+ Year Treasury Bond ETF) and EDV (Vanguard Extended Duration Treasury ETF) are both long-duration US Treasury bond funds used as interest rate hedges, deflation protection, or portfolio diversifiers. TLT holds Treasury bonds with maturities over 20 years (effective duration ~17 years) at 0.15% with massive liquidity ($55B AUM). EDV holds Treasury STRIPS with 20-30 year maturities (effective duration ~25 years) at a lower 0.06%, but with ~50% more price sensitivity to rate changes. If rates drop 1%, EDV gains roughly 25% while TLT gains about 17%. That leverage works both ways: rising rates in 2022-2023 caused TLT to fall ~40% and EDV to fall ~60%. Both are extremely volatile by bond standards and are not appropriate as core bond holdings for most investors.
Whether the lower-cost fund suits your situation depends on your existing holdings, account type, tax situation, and how you use each fund. This is a cost comparison, not a personalized recommendation.
