Is BST undervalued?
BST has a margin of safety of 87%: the stock closed at 46.03 on 5 Nov 2026 against a GLS average fair value of 348.58. 6 of the 9 valuation models that produced a number sit above the price. Our scans 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.
Ranked against every other company we cover, BST is clearly cheaper than it is fast-growing, so the nightly engine files it under Value (value score 91, growth score 45, out of 100). It also carries the Income tag (Income = a dividend yield of 4% or more).
Nine valuation models for BST
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.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 40.21 | -13% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 149.10 | +224% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 1,035.63 | +2150% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 452.63 | +883% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 1,108.41 | +2308% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 18.25 | -60% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 36.13 | -22% | Eight years of compounded free cash flow: the price at which the business pays for itself |

| EPV | 201.17 | +337% | Earnings power value: current EPS capitalised at 9% with no growth |

Quality and financial health
BlackRock Science and Technology Trust scores 6 of 9 on the Piotroski F-score: a middling result that passes the "Piotroski 6 or more" Wheel Trade Filter. 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. On durability BST scores 6.2/10 on the GLS Moat - a middle reading; the Moat Score tab on the Quote page's Financials view shows which of the four parts hold it back.
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 2.0%.
The dividend yield is high at 14.13% (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 | 6 / 9 | ROIC | 16.9% |
|---|---|---|---|
| GLS Moat | 6.2 / 10 | ROE | 16.9% |
| Debt / equity | 0.00 | ROA | 16.8% |
| Free-cash-flow yield | 2.0% | Payout ratio | 23% |
| Institutions | 3 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 33: No options
No options are listed on BlackRock Science and Technology Trust in our nightly snapshot, so it fails the first Wheel Trade Filter (options that actually trade) (it reads 33, under 70) and is left out of every options scan; the fair value and health figures above are still useful for a plain stock position.
Volume runs at 90k shares a day on a market cap of $1.6B, with a beta of 1.40 - 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 rates that fair.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Fails | no listed options |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Fails | no implied volatility |
| 8 | Big enough | Passes | Market cap $1 billion or more |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 87% below fair value | |
| Premium | Weak | no option data | |
| Moat | Good | moat 6.2/10 | |
| Health | Good | Piotroski 6/9 | |
| Red Flags | Fair | not scored yet - half marks | |
| Option trading | Weak | no option volume data | |
| Stability | Fair | beta 1.40, $1.6B company |
