Investment Thesis

For a Californian in the top brackets, CMF's 3.1% double-tax-free yield is worth over 6% pre-tax — the single most tax-efficient income stream a Golden State investor can buy in one ticker. The mildly negative year is muni duration in a rising-rate tape; the exemption mathematics are untouched.

Who It's For

California residents in high brackets, full stop — the double exemption is the entire product. Out-of-state investors should hold MUB/SUB instead.
