Is ACFN undervalued?
Acorn Energy, Inc. (ACFN) closed at 18.74 on 16 Oct 2026, close to the GLS average fair value of 17.59 (6.5% above fair value). 3 of the 8 models that produced a number sit above the price, 5 below - the market and our models roughly agree. With little margin of safety either way, the case for or against the stock rests on the quality numbers and the option premium rather than on price.
The 8 models disagree widely: EPV gives 6.84 while GLS Growth gives 37.66. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.

Quality and financial health
Financial health is average - ACFN passes 5 of the nine Piotroski tests, which falls one point short of the Sunday Scan's "6 or more" rule. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is 5.1 out of 10: a ten-year record that is consistent in some of the metrics the score tracks (revenue, earnings, margins, cash flow, returns on capital) and patchy in others.
Returns on capital are high - ROIC 27.0%, ROE 30.4%, ROA 18.8% - with debt at 0.13 times equity and a free-cash-flow yield of 3.1%.
Acorn Energy, Inc. 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 Monitoring 67%, Hardware 33% (quarter Q2 FY2026).
Institutional ownership scores 5/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | 27.0% |
|---|---|---|---|
| GLS Moat | 5.1 / 10 | ROE | 30.4% |
| Debt / equity | 0.13 | ROA | 18.8% |
| Free-cash-flow yield | 3.1% | Payout ratio | 0% |
| Institutions | 5 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 35: No options
ACFN has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business; the Wheel Score is capped at 39 and shown as "No options" (35 here). The valuation and quality numbers still apply to owning the shares outright.
Volume runs at 54k shares a day on a market cap of $47M, with a beta of 0.24 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 6 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 10 / 25 | -7% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 8 / 15 | moat 5.1/10 | |
| Premium | 0 / 20 | no option data | |
| Stability | 6 / 20 | 54k shares/day, $47M cap, beta 0.24 |
