PMMF: Bullish, But I'd Like To See Better Disclosure And I Remain Wary Of Untested Risks
The iShares Prime Money Market ETF offers exposure to a broad mix of cash products, including repos, CDs, and commercial paper. PMMF operates under Rule 2a-7, aiming to maintain NAV stability and mitigate 'break-the-buck' risk during market stress. The fund's prime money market status allows for non-government security exposure, resulting in varied liquidity profiles across holdings.
PMMF: Working As Designed
iShares Prime Money Market ETF offers intraday liquidity and regulatory protections under SEC Rule 2a-7, enhancing traditional money market fund structures. PMMF currently emphasizes repos and CDs, maintaining a short 40-day weighted average maturity and a 3.7% SEC yield with weekly distributions. PMMF has consistently outperformed both T-Bill ETFs and large mutual fund money market peers, delivering small but reliable alpha within a tightly regulated framework.
PMMF: Growth Rebound Calms Growth Mandate Response Forecast
The iShares Prime Money Market ETF (PMMF) eliminates duration risk amid growth rebound considerations and inflation still running hot. However, a growth rebound also makes some credit risk more appealing at the moment at low durations, provided by FLOT which also has a very low duration. Expense ratios are also lower on effectively similar low duration alternatives.
PMMF: New Prime Money Market ETF From iShares
PMMF is a newly launched ETF designed to offer intra-day trading liquidity for money market fund-like investments, adhering to SEC Rule 2a-7. This distinguishes it from traditional money market funds that operate with end-of-day NAV calculations. While aiming for high current income with liquidity and principal stability, PMMF's holdings, which include bank deposits and tri-party repos, introduce some counterparty credit risk, unlike pure T-Bill ETFs.
