BlackRock Taxable Municipal Bond Trust (BBN): fair value, margin of safety and Wheel Score

Is BBN undervalued?

At 14.93 (close of 5 Nov 2026), BBN trades 30% below the GLS average fair value of 21.36. That average comes from 8 models run on the latest filings, and 6 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns BlackRock Taxable Municipal Bond Trust the full Value points in the Wheel Score - and a closer look at what the market is pricing in.

The 8 models disagree widely: GLS Growth gives 2.87 while Graham Growth gives 56.11. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.

BBN looks like a fund, note or preferred share rather than an operating company, so the nightly engine files it under Fund / Note: the valuation models are not built for it, and its Wheel Score is capped at 45.

Nine valuation models for BBN

Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.

Quality and financial health

On financial health BBN scores 7/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. There is no GLS Moat score for BBN: funds, notes and second share lines get none, and so does a company with fewer than two years of accounts on file. The Moat part of the Wheel Score is zero.

Returns on capital are thin or negative - ROIC 4.8%, ROE 7.4%, ROA 4.8% - with debt at 0.53 times equity and a free-cash-flow yield of 6.8%.

The dividend yield is high at 7.92% (payout ratio 120%) - a payout above 100% of earnings, which is not covered by profits. A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual.

Institutional ownership scores 5/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 29: No options

BBN has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business. It fails the first Wheel Trade Filter (options that actually trade), so the score stays under 70 and is shown as "No options" (29 here). The valuation and quality numbers still apply to owning the shares outright.

Volume runs at 580k shares a day on a market cap of $923M, with a beta of 0.66 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls: a stock must pass all 9 Wheel Trade Filters to score 70, and the score then ranks the ones that pass; the Sunday Scan is the top 10. It is updated nightly and is not a recommendation. How the Wheel Score works · the walkthrough lesson shows how it fits into a trade, start to finish.

Upcoming events

No upcoming earnings date is recorded for BBN in the nightly calendar. The shares go ex-dividend on 13 Nov 2026 (0.0986 per share), so a covered call sold before then carries a small early-assignment risk around that date.
