Acorn Energy, Inc. (ACFN): fair value, margin of safety and Wheel Score

Is ACFN undervalued?

Acorn Energy, Inc. (ACFN) closed at 16.10 on 5 Nov 2026, close to the GLS average fair value of 17.65 (8.8% below 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.

Ranked against every other company we cover, ACFN is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 28, growth score 62, out of 100).

Nine valuation models for ACFN

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.

Quality and financial health

Financial health is average - ACFN passes 5 of the nine Piotroski tests, which falls one point short of the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is 6.0 out of 10: a record that is solid on some of the four parts the score weighs (returns on capital, pricing power, lasting growth, balance sheet) and weaker on 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 3.6%.

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.

Wheel Score 23: 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. It fails the first Wheel Trade Filter (options that actually trade), so the score stays under 70 and is shown as "No options" (23 here). The valuation and quality numbers still apply to owning the shares outright.

Volume runs at 70k shares a day on a market cap of $40M, with a beta of 0.26 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls: a stock must pass all 9 Wheel Trade Filters to score 70, and the score then ranks the ones that pass; the Sunday Scan is the top 10. It is updated nightly and is not a recommendation. How the Wheel Score works · the walkthrough lesson shows how it fits into a trade, start to finish.
