TLT iShares 20+ Year Treasury Bond ETF

Events before 24 September 2026 were rebuilt on 26 September 2026 with the rules in use now; they were not published at the time. From 24 September 2026 they are as published. The record starts on 28 February 2025: before that there is not enough history to judge a session.

Turnover here is dollar volume as a share of the fund's assets, not of market cap. We hold one assets figure per fund, the latest, so an event's turnover is measured against the assets held when it was published or rebuilt, not necessarily that day's. The multiple of normal compares dollar volume alone and does not depend on it.

Composition

Bond funds hold thousands of individual issues and do not publish a top-ten or sector breakdown in a comparable form.

Dollar volume as a share of assets. High turnover means a fund is being traded hard relative to its size — often a sign of active positioning rather than buy-and-hold ownership.
