Hudson Technologies, Inc. (HDSN): fair value, margin of safety and Wheel Score
Ticker symbol HDSN · Basic Materials · Chemicals - Specialty · United States · Speculative
Is HDSN undervalued?
Hudson Technologies, Inc. (HDSN) closed at 4.41 on 5 Nov 2026. The GLS average fair value - the simple average of the 1 valuation models that produced a positive number - is 16.48, which puts the price 73% below it. 1 of the 1 models value the shares above the current price. A gap this wide is rare in our universe of ~7,400 US stocks and is exactly what the Value part of the Wheel Score rewards; it is also where the question "why is it this cheap?" matters most.
The average is built from just 1 models (DCF) - 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 HDSN 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 HDSN
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.

| 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 |

Quality and financial health
Hudson Technologies, Inc. scores only 2 of 9 on the Piotroski F-score, which fails the "Piotroski 6 or more" Wheel Trade Filter. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. On durability HDSN scores 5.6/10 on the GLS Moat - a middle reading; the Moat Score tab on the Quote page's Financials view shows which of the four parts hold it back.
Returns on capital are moderate - ROIC 6.7%, ROE 6.8%, ROA 5.2% - with debt at 0.02 times equity and negative free cash flow.
Hudson Technologies, 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 97%, Refrigerant Side Services 3% (quarter Q2 FY2026).
Institutional ownership scores 9/10, insider activity 8/10 and Congressional trading 5/10 on the GLS smart-money scales; the last recorded insider buy was on 2 Nov 2026.
| Piotroski F-score | 2 / 9 | ROIC | 6.7% |
|---|---|---|---|
| GLS Moat | 5.6 / 10 | ROE | 6.8% |
| Debt / equity | 0.02 | ROA | 5.2% |
| Free-cash-flow yield | -17.0% | Payout ratio | 0% |
| Institutions | 9 / 10 | Insiders · Congress | 8 · 5 / 10 |
Wheel Score 38: Weak
With a Wheel Score of 38 Hudson Technologies, 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 4, financially healthy - Piotroski 2/9 (under 6); and filter 8, big enough - market cap $186M (under $1.0B); and filter 9, not a penny stock - price 4.41 (under $5); Option trading (weak) is its weakest part.
Implied volatility is 75% on the near-the-money contracts 20-60 days out - above the 60% top of the sweet spot. It still passes the 25-80% filter, but the Wheel Score rewards it less because volatility this high usually comes with a reason. Chain open interest is thin - 1,548 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 770k shares a day on a market cap of $186M, with a beta of 0.89; 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 | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Fails | Piotroski 2/9 (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 | Fails | market cap $186M (under $1.0B) |
| 9 | Not a penny stock | Fails | price 4.41 (under $5) |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Strong | 73% below fair value | |
| Premium | Good | implied volatility 75% | |
| Moat | Fair | moat 5.6/10 | |
| Health | Weak | Piotroski 2/9 | |
| Red Flags | Fair | Red Flags score 70/100 | |
| Option trading | Weak | 156 contracts a day, 1,548 open interest | |
| Stability | Fair | beta 0.89, $186M company |
