California Water Service Group (CWT): fair value, margin of safety and Wheel Score
Ticker symbol CWT · Utilities · Regulated Water · United States · Blend
Is CWT undervalued?
CWT closed at 49.96 on 5 Nov 2026, more than 30% above the GLS average fair value of 25.23. Only 0 of the 6 models that produced a value sit above the price. By our models the shares are priced well beyond what the filed earnings, cash flow and book value support; the "below fair value" Wheel Trade Filter keeps names like this under 70.
The 6 models disagree widely: GLS Growth gives 10.35 while Graham Growth gives 44.91. 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, neither cheapness nor growth clearly wins for CWT, so the nightly engine files it under Blend (value score 31, growth score 24, out of 100).
Nine valuation models for CWT
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 | - | - | Present value of the projected free cash flows, discounted at the cost of capital; no value tonight |
| Graham Number | 38.88 | -22% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 44.91 | -10% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 13.60 | -73% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 10.35 | -79% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | - | - | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10%; no value tonight |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | 19.20 | -62% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 24.47 | -51% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | -57.65 | -215% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 53.00 | +6% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is average - CWT passes 6 of the nine Piotroski tests, which passes the "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is 5.4 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 thin or negative - ROIC 3.9%, ROE 7.6%, ROA 2.3% - with debt at 0.96 times equity and negative free cash flow.
The dividend yield is 2.61% at a payout ratio of 57%; for a wheel trader holding assigned shares the dividend adds to the covered-call premium, and the ex-dividend date is worth knowing before a call is sold. Revenue comes mainly from Residential 63%, Business 20%, Public Authorities 7% (quarter Q3 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 3.9% |
|---|---|---|---|
| GLS Moat | 5.4 / 10 | ROE | 7.6% |
| Debt / equity | 0.96 | ROA | 2.3% |
| Free-cash-flow yield | -8.5% | Payout ratio | 57% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 25: Weak
CWT scores 25 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 1, options that actually trade - options too quiet (285 open interest, 139 a day); and filter 3, below fair value - trades 98% above our fair value, and the parts are thin too - value weak, premium fair, moat fair, health good, red flags fair, option trading weak, stability fair. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility is 26% on the near-the-money contracts 20-60 days out: enough to pass the 25-80% Wheel Trade Filter, but under the 35-60% sweet spot the score rewards most. Chain open interest is thin - 285 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 691k shares a day on a market cap of $3.1B, with a beta of 0.47 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that fair.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Fails | options too quiet (285 open interest, 139 a day) |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Fails | trades 98% above our fair value |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 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 | 98% above fair value | |
| Premium | Fair | implied volatility 26% | |
| Moat | Fair | moat 5.4/10 | |
| Health | Good | Piotroski 6/9 | |
| Red Flags | Fair | Red Flags score 72/100 | |
| Option trading | Weak | 139 contracts a day, 285 open interest | |
| Stability | Fair | beta 0.47, $3.1B company |
