AB Tax-Aware Long Municipal ETF

AB Tax-Aware Long Municipal ETF (TAFL) is an actively managed AllianceBernstein fund. It holds mostly long-term municipal bonds whose interest is free from federal income tax, and its managers can add taxable bonds and swaps when those look better after tax. It costs 0.28% a year, below the 0.39% average of similar funds. It is also the smallest in its group, with $67.6 million in assets as of August 31, 2026.

• Over the year to Oct 27, 2026, TAFL returned -1.0%, 7th of 8 among similar funds.
• Its worst full calendar year was 2024 (+2.0%); its best was 2025 (+3.5%).
• The deepest fall in its price history was 7.8% (Jul 6, 2026 to Sep 29, 2026), not yet recovered.

As of Aug 31, 2026, the fund held 128 securities; the ten largest made up 19.24% of assets.

The bonds mature in 23.5 years on average (weighted by size), with an average coupon of 5.06%.

• Over the three months to Aug 31, 2026, investors added a net $11.2M (creations minus redemptions, per the N-PORT report).
• Monthly total returns reported for that quarter: +1.12%, -1.71%, -0.40%.

This actively managed AllianceBernstein fund tracks no index. At least 80% of net assets normally sit in municipal bonds from states, cities and agencies, paying interest free of federal income tax (some may be subject to the alternative minimum tax). The rest can hold taxable bonds when they should beat municipal bonds after federal tax; state and local taxes aren’t counted. Puerto Rico debt and lower-rated “junk” bonds are allowed, but junk is not the main focus.

The manager weighs credit quality, maturity, diversification and after-tax return, plus the tax cost of selling. It targets an effective duration (price sensitivity to interest rates) of seven to fourteen years, which is long. Its largest holdings on August 31, 2026, were Triborough Bridge & Tunnel Authority sales-tax bonds (2.7%), Wisconsin Public Finance Authority toll bonds (2.4%) and Chicago waterworks bonds (2.3%). Several airport bonds followed at about 1.6% each, and the fund may hold over 25% in bonds tied to similar projects.

Derivatives, mainly swaps, can hedge, add income or create leverage by pushing exposure beyond net assets. It held 17 on August 31, 2026, including interest-rate and inflation swaps. Because shares can be created and redeemed in cash, the prospectus expects the fund to be less tax-efficient than ETFs that exchange securities instead.

• TAFL charges 0.28% a year, versus an average of 0.39% for the similar funds below (3rd of 8, cheapest first).
• Using the prospectus's standard example, $10,000 invested would cost about $29 in the first year and $356 over 10 years (assuming a 5% annual return).

It pays monthly income that is mostly exempt from federal income tax, with a 4.33% trailing yield as of October 27, 2026.

TAFL could provide monthly income that is mostly free of federal tax, held in a taxable account. Over the 12 months to October 27, 2026, it paid $1.04 per share, a trailing yield of 4.33%. Costs are modest. In the SEC's standard example, $10,000 invested would cost $29 in the first year and $356 over 10 years.

The fund launched in December 2023, so it missed the 2008, 2020 and 2022 sell-offs. Its weakest calendar year was 2024, when it gained 2.25%, according to the prospectus. Its deepest drop was 7.8%, from July 6 to September 29, 2026, and it had not recovered as of October 27, 2026. Because it holds long-maturity bonds, a rate jump could force a retiree who needs cash to sell at a loss. Past results don't predict future ones, and a plan should look at the whole portfolio, not one fund.
