State Street Prime Money Market ETF (MMK) Price & Chart

State Street Prime Money Market ETF

State Street Prime Money Market ETF (MMK) is an actively managed, ultra-short‑term ETF that seeks to provide income, preserve capital and maintain liquidity by broadly investing in high‑quality money market and short‑dated credit instruments from around the world. Unlike government‑only cash funds, MMK targets a broad‑credit opportunity set—including negotiable certificates of deposit, commercial paper, short‑term corporate notes and repurchase agreements—allowing the manager to pursue incremental yield across a diversified pool of issuers. The fund’s in‑house credit research team conducts issuer‑level analysis and relative‑value assessments to select securities that balance yield potential with credit quality and liquidity. Portfolio construction emphasizes an ultra‑short weighted average maturity to limit interest‑rate sensitivity and make the ETF suitable for cash management, short‑term parking of assets, or as a low‑volatility sleeve within a larger portfolio. As a broadly focused, ultra‑short credit solution, MMK offers investors broader credit exposure than government money market alternatives while retaining the conservative characteristics typical of cash‑management strategies. Investors should note that MMK is subject to credit, liquidity and market risks and is not insured or guaranteed by any government agency.
