The players

iShares 20+ Year Treasury Bond ETF

An exchange-traded fund that tracks the performance of U.S. Treasury bonds with 20 or more years remaining until maturity.

The details

The fund's share price fell as traders offloaded long-dated Treasury bonds in the open market. Because the price of existing bonds generally moves inversely to yields, the selloff pushed the fund lower. This mechanism impacts the value of portfolios heavily weighted toward long-term fixed-income products.
