BlackRock Science and Technology Trust (BST): fair value, margin of safety and Wheel Score
Financial Services · Asset Management · United States · High Yield Income
Is BST undervalued?
BST has a margin of safety of 86%: the stock closed at 48.55 on 16 Oct 2026 against a GLS average fair value of 348.52. 6 of the 9 valuation models that produced a number sit above the price. Our screens treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
There is a wide gap between 10 Cap (18.25) and GLS Growth (1,108.41). 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 BST under High Yield Income: a dividend yield above 4%.

| DCF | 39.65 | -18% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 149.10 | +207% | The most a defensive investor pays for the earnings and book value per share |

| GLS Growth | 1,108.41 | +2183% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |

Quality and financial health
BlackRock Science and Technology Trust scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of the Sunday Scan's "6 or more" rule. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 2.6/10 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 16.9%, ROE 16.9%, ROA 16.8% - with debt at 0.00 times equity and a free-cash-flow yield of 1.9%.
The dividend yield is high at 13.40% (payout ratio 23%). 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 3/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | 16.9% |

Wheel Score 39: No options
No options are listed on BlackRock Science and Technology Trust 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 91k shares a day on a market cap of $1.7B, with a beta of 1.38 - 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 8 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 86% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 4 / 15 | moat 2.6/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 8 / 20 | 91k shares/day, $1.7B cap, beta 1.38 |
