Enter a ticker to learn what the company does and how it makes money.
This fund owns a big basket of long-term U.S. government bonds, giving investors a simple way to hold Treasurys that mature in more than 20 years.
This is a fund, not a normal company. It holds a large collection of U.S. Treasury bonds β the IOUs the American government sells to borrow money β and it only buys the ones that come due in more than 20 years. An investor who buys a share gets a tiny slice of that whole pile of very long-dated government debt, packaged into one easy trade.

The point of the fund is to track a market-value-weighted index of those long Treasurys. In plain words, it holds the same bonds, in roughly the same proportions, as the index it follows, so its returns should rise and fall almost in lockstep with that slice of the bond market. It is a passive "BetaBuilders" product, meaning it is built to copy the market cheaply rather than to have a manager pick winners. Long bonds behave very differently from short ones. Because the money is tied up for decades, their prices swing hard when interest rates move β more than almost anything else in the bond world. When rates fall, these bonds can jump in price; when rates climb, they can fall sharply. So investors typically use a fund like this either to make a deliberate bet that rates will drop, or as a piece of a bigger portfolio that wants long-term government exposure.
The fund earns its keep by charging a small management fee, a sliver of assets each year, which is how the issuer, J.P. Morgan, gets paid for running it. It is listed on Cboe US and trades like a stock, so anyone with a brokerage account can buy or sell shares during the day. The appeal is simplicity and low cost: one ticker gives you a ready-made holding of long-dated Treasurys without buying individual bonds.
