Key Metrics to Screen For
1. Annualized Premium Yield
This is the single most important number. It tells you what percentage return you'd earn if you could sell the same call repeatedly for a year.
Formula: (Premium / Stock Price) × (365 / DTE) × 100
Example: $2.50 premium on a $100 stock with 30 DTE = (2.50/100) × (365/30) × 100 = 30.4% annualized
Screen for yields between 15-40%. Below 15% isn't worth the hassle. Above 40% usually means the stock is highly volatile or has earnings coming up.
2. Delta
Delta approximates the probability of the option expiring in the money. For covered calls:
Most systematic covered call sellers target the 0.20-0.30 delta range.
3. Days to Expiration (DTE)
Screen for 25-45 DTE. This window captures the steepest theta decay curve while giving you enough time premium to collect meaningful income. Shorter than 20 DTE has thin premiums. Longer than 50 DTE ties up your capital and has slower theta decay.
4. Open Interest and Volume
Minimum open interest of 100 contracts and daily volume of 50+ ensures tight bid-ask spreads. Illiquid options will cost you 5-15% of the premium just on the spread.
5. Earnings Date Filter
Exclude any stock with earnings within your option's expiration window. Post-earnings IV crush destroys the premium you were counting on, and the stock gap risk can be enormous.
Building a Screener From Scratch
If you're using a platform like thinkorswim or Power E*TRADE:
What a Good Screener Result Looks Like
| Stock | Price | Strike | DTE | Premium | Annual Yield | Delta | OI |
AMD and ABBV offer solid yields with reasonable deltas and deep liquidity. F has high yield but the low stock price means small dollar amounts per contract.
Common Screener Mistakes
Chasing the highest yield. A stock showing 80% annualized yield is screaming that the market expects massive price movement. That premium exists because the risk is enormous.
Ignoring the underlying stock quality. Screening only by premium yield without considering whether you'd want to own the stock for months is a recipe for bagholding.
Not accounting for dividends. Ex-dividend dates increase early assignment risk on in-the-money calls. Screen for ex-dates and adjust your strategy accordingly.
OptionsPilot's Built-In Screener
OptionsPilot's covered call finder scans your watchlist and portfolio holdings automatically, ranking every available strike by annualized yield with filters for delta, DTE, and liquidity. It highlights which trades meet your income targets and flags any that have earnings or ex-dividend dates before expiration — so you can go from screening to execution in seconds rather than building spreadsheets.
