Is CPST undervalued?
Calamos S&P 500 Structured Alt Protection ETF - September (CPST) closed at 28.24 on 5 Nov 2026. None of the nine GLS valuation models produced a positive value for the stock - the company lost money over the last twelve months, EPS -2.26, it pays no dividend and its debts exceed what its assets would fetch - so there is no GLS average fair value and no margin of safety to report. The quality, option and event numbers below still apply; the Quote page's Wall Street View shows what analysts expect instead.
CPST looks like a fund, note or preferred share rather than an operating company, so the nightly engine files it under Fund / Note: the valuation models are not built for it, and its Wheel Score is capped at 45.
Nine valuation models for CPST
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 | - | - | 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 | - | - | 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 | - | - | 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) | -3.63 | -113% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 0.0000 | -100% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is weak: CPST passes 1 of the nine Piotroski tests. Our scans drop the stock at the health filter; a low score is often the reason a stock looks cheap on the valuation models. There is no GLS Moat score for CPST: funds, notes and second share lines get none, and so does a company with fewer than two years of accounts on file. The Moat part of the Wheel Score is zero.
Returns on capital are thin or negative - ROIC -39.5%, ROE -141.2%, ROA -24.9% - with debt at 2.57 times equity and negative free cash flow. Debt of 2.57 times equity is on the high side for the sector and is worth checking against the cash flow before treating the stock as a long-term hold.
Calamos S&P 500 Structured Alt Protection ETF - September pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain.
Institutional ownership scores 10/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 1 / 9 | ROIC | -39.5% |
|---|---|---|---|
| GLS Moat | - / 10 | ROE | -141.2% |
| Debt / equity | 2.57 | ROA | -24.9% |
| Free-cash-flow yield | -73.6% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 8: No options
CPST 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" (8 here). The valuation and quality numbers still apply to owning the shares outright.
Volume runs at 0k shares a day on a market cap of $32M, with a beta of 0.18 - 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 | no listed options |
| 2 | A real business, not a gamble | Fails | a fund or note, not a company |
| 3 | Below fair value | Fails | trades right at our fair value |
| 4 | Financially healthy | Fails | Piotroski 1/9 (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 | Fails | no implied volatility |
| 8 | Big enough | Fails | market cap $32M (under $1.0B) |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Weak | 0% below fair value | |
| Premium | Weak | no option data | |
| Moat | Weak | no moat score | |
| Health | Weak | Piotroski 1/9 | |
| Red Flags | Fair | not scored yet - half marks | |
| Option trading | Weak | no option volume data | |
| Stability | Fair | beta 0.18, $32M company |
