BlackRock Science and Technology Trust II (BSTZ): fair value, margin of safety and Wheel Score

Is BSTZ undervalued?

At 27.95 (close of 16 Oct 2026), BSTZ trades 93% below the GLS average fair value of 413.55. That average comes from 6 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 Science and Technology Trust II the full Value points in the Wheel Score - and a closer look at what the market is pricing in.

There is a wide gap between DDM (60.53) and GLS Growth (916.15). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.

The nightly engine files BSTZ under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.

Nine valuation models for BSTZ

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.

Quality and financial health

BlackRock Science and Technology Trust II scores only 3 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. A GLS Moat score of 3.4/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.

Returns on capital are high - ROIC 18.1%, ROE 18.3%, ROA 17.9% - with debt at 0.01 times equity and negative free cash flow.

The dividend yield is high at 14.72% (payout ratio 17%). 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 4/10, insider activity 9/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 39: No options

No options are listed on BlackRock Science and Technology Trust II in our nightly snapshot. The Wheel Score is therefore capped at 39 (it reads 39) and the stock is left out of every options screen; the fair value and health figures above are still useful for a plain stock position.

Volume runs at 150k shares a day on a market cap of $1.9B, with a beta of 1.50 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 9 of 20.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls; it is updated nightly and is not a recommendation. The walkthrough lesson shows how the score fits into a trade, start to finish.

Upcoming events

No upcoming earnings date is recorded for BSTZ in the nightly calendar. The shares go ex-dividend on 13 Nov 2026 (0.1625 per share), so a covered call sold before then carries a small early-assignment risk around that date.
