Head-to-head over the 11-year window both funds have in common (2015-09-14 → 2026-09-11): TLT (iShares 20+ Year Treasury Bond ETF) vs IEF (iShares 7-10 Year Treasury ETF) — total return with dividends reinvested, both starting at $10,000 on the same date.
On risk-adjusted return, IEF came out ahead of TLT —
but the gap is only half the story. Drawdown and yield often matter more.
