How to read a cash-secured put candidate
Assume one standard 100-share contract, a $50 strike, a $1.00 premium per share, and 30 days to expiration. This example excludes fees, taxes, and interest on collateral.
| Metric | Example | What it means |
|---|---|---|
| Strike / time remaining | $50 / 30 days | The agreed purchase price and remaining contract term. |
| Premium received | $100 | $1.00 per share × 100 shares. This is cash received, not guaranteed profit. |
| Gross cash obligation | $5,000 | $50 × 100 shares if assigned. Broker cash requirements can differ. |
| Period premium yield | 2.00% | $100 ÷ $5,000, using gross strike collateral as the denominator. |
| Simple annualized yield | 24.33% | 2% × 365 ÷ 30. A comparison metric, not an expected annual return. |
| Expiration breakeven | $49 per share | Strike minus premium per share, before costs. |
If the stock is worth $40 at expiration and the put is assigned, the shares are worth $4,000 against a $5,000 purchase obligation. Including the $100 premium, the net loss is $900 before costs. If the stock becomes worthless, the loss is $4,900.
These calculations use the stated example convention. Check the live scanner’s field definitions and quote basis before comparing its metrics with this illustration.
What to check beyond the highest premium
- Assignment commitment. Decide whether you can fund and are willing to hold the resulting shares, including during a price decline.
- Expiration and events. Check earnings dates and other company events against the contract term. TradeGemini’s earnings filter helps narrow the list; it does not eliminate event risk.
- Execution. Inspect the bid/ask spread, liquidity, and data timestamp. An indicative or modeled premium may not be executable.
- Return definition. Compare like-for-like collateral and time periods. Annualization assumes repetition that actual trading may not achieve.
- Portfolio exposure. Several puts in related companies can create concentrated exposure if assigned together.

Common questions
What is a CSP screener?
A cash-secured put screener narrows a set of stocks and put contracts using screening criteria. It helps organize research; it does not guarantee a profitable trade or protect against a fall in the underlying stock.
Is TradeGemini’s full screener free?
The full Wheeling Hub scanner requires Premium+ access. This public page is an educational preview. Check pricing for current subscription and trial terms.
Which controls does the scanner offer?
Choose your watchlist or the curated universe, a goal preset, and a days-to-expiration bucket. The scanner also includes an earnings-risk filter. Open the app to inspect the current controls and candidate details.
Does a high annualized yield mean a better trade?
No. A high quoted premium can accompany greater uncertainty or downside exposure. Review the underlying company, contract terms, and execution costs before interpreting a yield figure.
