Boston Scientific Corporation (BSX): fair value, margin of safety and Wheel Score
Healthcare · Medical - Devices · United States · High Growth
Is BSX undervalued?
BSX has a margin of safety of 33%: the stock closed at 44.14 on 16 Oct 2026 against a GLS average fair value of 65.77. 5 of the 8 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 Lynch (21.32) and GLS Growth (151.93). 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 BSX under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

| Lynch | 21.32 | -52% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 151.93 | +244% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |

Quality and financial health
Boston Scientific Corporation scores 8 of 9 on the Piotroski F-score, the nine yes/no tests of profitability, leverage and efficiency on the latest annual accounts - a strong reading that passes the Sunday Scan's "6 or more" rule with room to spare. A GLS Moat score of 7.9/10 puts BSX among the more durable businesses we track: over ten years the metrics the score watches (revenue, EPS, book value, margins, cash flow, ROIC) have mostly moved the right way, year after year.
Returns on capital are moderate - ROIC 7.9%, ROE 11.9%, ROA 6.6% - with debt at 0.51 times equity and a free-cash-flow yield of 5.7%.
Boston Scientific Corporation pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Cardiovascular 67%, Med Surg 33% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 10/10 and Congressional trading 1/10 on the GLS smart-money scales; the last recorded Congressional buy was on 18 Aug 2026.
| Piotroski F-score | 8 / 9 | ROIC | 7.9% |
|---|---|---|---|
| GLS Moat | 7.9 / 10 | ROE | 11.9% |
| Debt / equity | 0.51 | ROA | 6.6% |
| Free-cash-flow yield | 5.7% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 10 · 1 / 10 |
Wheel Score 95: Prime
With a Wheel Score of 95, Boston Scientific Corporation sits in the Prime band - price, quality and premium all line up for the wheel strategy. The parts: Value 25/25, Health 18/20, Moat 12/15, Premium 20/20, Stability 20/20. A high score is a ranking, not a signal: it says nothing about timing, the earnings date or your position size.
Implied volatility is 51% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. The option chain is deep: 899,633 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 13.6M shares a day on a market cap of $64.0B, with a beta of 0.57 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 20 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 33% margin of safety | |
| Health | 18 / 20 | Piotroski 8/9 | |
| Moat | 12 / 15 | moat 7.9/10 | |
| Premium | 20 / 20 | implied volatility 51% | |
| Stability | 20 / 20 | 13.6M shares/day, $64.0B cap, beta 0.57 |
