Harmonic Inc. (HLIT): fair value, margin of safety and Wheel Score
Ticker symbol HLIT · Technology · Communication Equipment · United States · Speculative
Is HLIT undervalued?
Harmonic Inc. (HLIT) closed at 10.21 on 5 Nov 2026, 403% above the GLS average fair value of 2.03. 2 of the 2 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.
The average is built from just 2 models (DCF, 10 Cap) - the rest returned nothing because an input they need (dividends, free cash flow, book value) is zero or negative - so treat it with more caution than usual.
The nightly engine files HLIT under Speculative - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for HLIT
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 | 1.81 | -82% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | - | - | The most a defensive investor pays for the earnings and book value per share; no value tonight |
| Graham Growth | - | - | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields; no value tonight |
| Lynch | - | - | EPS × the earnings growth rate (PEG of 1), growth capped at 25%; no value tonight |
| GLS Growth | - | - | EPS compounded ten years at the blended growth rate, discounted back at 15% a year; no value tonight |
| 10 Cap | 2.25 | -78% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | - | - | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend; no value tonight |
| EPV | - | - | Earnings power value: current EPS capitalised at 9% with no growth; no value tonight |
| Zombie (liquidation) | 1.46 | -86% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 17.50 | +71% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Harmonic Inc. scores 5 of 9 on the Piotroski F-score: a middling result that falls one point short of 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. A GLS Moat score of 3.8/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, so the Moat part of the Wheel Score contributes little.
Returns on capital are thin or negative - ROIC -8.2%, ROE -11.3%, ROA -6.0% - with debt at 0.39 times equity and a free-cash-flow yield of 2.5%.
Harmonic 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 Product 89%, Professional Services 11% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | -8.2% |
|---|---|---|---|
| GLS Moat | 3.8 / 10 | ROE | -11.3% |
| Debt / equity | 0.39 | ROA | -6.0% |
| Free-cash-flow yield | 2.5% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 33: Weak
With a Wheel Score of 33 Harmonic Inc. sits in the Weak band. It fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 3, below fair value - trades 403% above our fair value; and filter 4, financially healthy - Piotroski 5/9 (under 6); Value (weak) is its weakest part.
Implied volatility is 54% on the near-the-money contracts 20-60 days out - inside the 35-60% sweet spot the Wheel Score rewards most: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is 3,751 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 2.3M shares a day on a market cap of $1.1B, with a beta of 1.37 - 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 | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Fails | trades 403% above our fair value |
| 4 | Financially healthy | Fails | Piotroski 5/9 (under 6) |
| 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 | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 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 | Weak | 403% above fair value | |
| Premium | Strong | implied volatility 54% | |
| Moat | Fair | moat 3.8/10 | |
| Health | Fair | Piotroski 5/9 | |
| Red Flags | Strong | Red Flags score 95/100 | |
| Option trading | Weak | 138 contracts a day, 3,751 open interest | |
| Stability | Fair | beta 1.37, $1.1B company |
