What is TLT's observed maximum drawdown?

TLT's observed maximum drawdown was 47.6%, from a peak in 2020-07-31 to a trough in 2023-10-31, based on monthly closes from fund prices first observed on 2002-07-26. The sample contains 291 monthly observations through 2026-09-30. Monthly closes can miss deeper daily losses.

Methodology: observed TLT fund prices only, first available from 2002-07-26. Monthly closing-price statistics cover 2002-07-31 through 2026-09-30; no proxy or pre-inception simulation is included in this table. Educational information, not investment advice.

Hypothetical, not observed

Before 2002-07-26: simulated from the underlying index with assumptions

This separate series combines observed prices with a modeled pre-inception extension from 1970-01-31 through 2026-10-31. The 2026-10-31 endpoint is the legacy current partial-month bucket/month-end label, not evidence that TLT was observed through that future date. It is not observed TLT performance. The API's observed boundary is 2002-07-26; observed monthly statistics run from 2002-07-31 through 2026-09-30.
