Is BELFB undervalued?
Bel Fuse Inc. (BELFB) closed at 219.07 on 16 Oct 2026, 103% above the GLS average fair value of 108.01. 9 of the 9 models that produced a number value the shares below the current price. A gap this wide usually means the market is paying for growth or a story the trailing numbers do not show yet; the models work from filed results, not forecasts, so they are conservative by design.
There is a wide gap between DDM (4.12) and Graham Growth (195.03). 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 BELFB under High Growth: revenue and earnings growing fast enough that the growth-based models carry the valuation.

Quality and financial health
Bel Fuse Inc. 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. On durability BELFB scores 6.3/10 on the GLS Moat - a middle reading; the Scorecard on the Quote page's Financials tab shows which ten-year lines are steady and which are not.
Returns on capital are moderate - ROIC 9.5%, ROE 14.5%, ROA 6.6% - with debt at 0.52 times equity and a free-cash-flow yield of 2.7%.
The dividend yield is 0.13% with a payout ratio of 6% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Power Solutions and Protection 58%, Magnetic Solutions 42% (quarter Q4 FY2025).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 8 / 9 | ROIC | 9.5% |
|---|---|---|---|
| GLS Moat | 6.3 / 10 | ROE | 14.5% |
| Debt / equity | 0.52 | ROA | 6.6% |
| Free-cash-flow yield | 2.7% | Payout ratio | 6% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 57: Fair
A Wheel Score of 57 puts Bel Fuse Inc. in the Fair band - below the 70 the Sunday Scan requires. Value 0/25, Health 18/20, Moat 9/15, Premium 19/20 and Stability 11/20; the weakest part is Value (0/25).
Implied volatility is 64% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (19 of 20) because volatility this high usually comes with a reason. Chain open interest is thin - 1,154 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 203k shares a day on a market cap of $2.7B, 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 11 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -103% margin of safety | |
| Health | 18 / 20 | Piotroski 8/9 | |
| Moat | 9 / 15 | moat 6.3/10 | |
| Premium | 19 / 20 | implied volatility 64% | |
| Stability | 11 / 20 | 203k shares/day, $2.7B cap, beta 1.38 |
