Our read on AMUN
CAn actively run ultra-short muni portfolio with roots to 1986, now in an ETF wrapper. The team hand-picks bonds and holds duration near two years or less, targeting federally tax-exempt income with less rate whiplash than long munis.
The fund seeks high after-tax current income while preserving capital.
Why people hold it
- Active, not an index tracker: the team picks credits and keeps weighted average effective duration around two years or less, dialing down interest-rate sensitivity versus longer muni funds.regulated-documents.saytechnologies.com
- Long lineage for the category: the strategy dates to 1986 and reached the market as an ETF through a fund conversion, run by Aberdeen's fixed income leadership.aberdeeninvestments.com
- Income mechanics are simple: at least 80% of assets in investment-grade tax-exempt munis, interest free from federal income tax (AMT can apply), distributions paid monthly.regulated-documents.saytechnologies.com
- The portfolio stays in the lane the prospectus advertises: US, ultra-short, investment-grade municipal bonds, with no drift into other asset classes.
Worth knowing
- You pay active-management prices. The fee runs several times the short-muni cohort median, where index rivals like VTES (0.05%) and SUB (0.07%) sit.
- Small and thinly traded next to the giants of the muni aisle, so bid-ask spreads can be wider and large orders may move the price.
- Credit flexibility cuts both ways: up to a fifth of assets can sit outside investment grade, and the fund is not required to sell a bond whose rating slips below it.regulated-documents.saytechnologies.com
