iShares Prime Money Market ETF (PMMF)

The iShares Prime Money Market ETF (PMMF) is an actively managed fund from iShares, the exchange-traded fund business of BlackRock. It invests in high-quality, short-term money market instruments with the aim of providing current income while preserving capital and liquidity.

As a prime fund, it can hold not only U.S. government securities but also short-term corporate and bank obligations such as commercial paper, certificates of deposit and repurchase agreements. Unlike a traditional money market mutual fund, its shares trade on an exchange throughout the day at market prices.

PMMF is listed on the New York Stock Exchange.
