How to screen stocks for the wheel, step by step
Screening for the wheel is five checks in a fixed order: can you afford it, do its options trade, does it pay enough, is the business sound, and is there an earnings date in the way. Here's each step with the numbers to look for.
The short answer
Screen stocks for the wheel strategy in this order: price, liquidity, implied volatility, quality, earnings date. Each step throws names out. What's left is a short list of stocks you could own, whose options you can trade, that pay enough to bother with, with no known shock inside the expiry.
Run it once a month. The order matters: the cheap checks first, so you don't study the finances of a stock you can't afford.
Step 1: Price (can you afford to be assigned?)
A cash-secured put sets aside the strike × 100. A covered call needs 100 shares. So the first filter is the share price.
- Work out the most cash you'd put in one name: some sellers use a fifth of the account or less.
- Divide by 100. That's your top share price.
- Throw out everything above it.
With a $10,000 account and a one-fifth rule, that's stocks under about $20. With $25,000, under about $50. Our guide on how much money the wheel strategy needs has the full sizing rule.
Canada: the same math applies in a TFSA or RRSP. Covered calls are widely allowed; cash-secured puts depend on the broker. Options permissions differ by broker.
Step 2: Liquidity (do its options actually trade?)
Open the Options chain about 30 to 45 days out. Look at the put strike roughly 5% below the price and the call strike 5% above. For each:
- Open interest: hundreds of contracts, not dozens.
- Spread: the bid-ask gap is a few cents, or under about a tenth of the mid price.
- Volume today: more than zero.
A thin chain costs you a slice of every premium and can trap you when you need to close. See how to check an option's liquidity. Throw out anything that fails.
Step 3: Implied volatility (does it pay enough, and not too much?)
Implied volatility sets the premium. Too low, and the premium isn't worth capping your upside or tying up the cash. Too high, and the market is warning you about something.
Use IV rank: where today's IV sits between the stock's low and high over the past year, from 0 to 100.
- Under about 20: the premium is probably thin. Maybe wait.
- Roughly 30 to 60: enough to pay, nothing alarming.
- Over about 80: ask why. Earnings, a lawsuit, a slide. Usually a skip.
The full reading is in using IV rank to pick stocks.
Step 4: Quality (would you own this for a year?)
Now, and only now, open the company's numbers. In plain words:
- Does it make a profit? Both of the last two years.
- Can it carry its debt? Debt that's small next to what the business owns, and cash coming in to pay the interest.
- Is cash actually coming in? Free cash flow positive.
- Are sales growing, or at least not shrinking?
A stock that fails here is a falling knife waiting to happen. The checklist is in quality checks before you wheel a stock.
Step 5: Earnings date (is there a known shock inside the expiry?)
Find the next earnings date. If it falls before your expiry, either pick an expiry before it or skip the name this month. An earnings gap is a common way a wheel put ends up deep in the money overnight. See check the earnings date before you sell.
Also note any ex-dividend date; it matters for covered calls.
The screen as one table
| Step | Check | Pass | Fail |
|---|---|---|---|
| 1 Price | Strike × 100 vs your cap | Fits in one fifth of the account | Too big |
| 2 Liquidity | OI and spread at your strike | Hundreds; a few cents | Dozens; a wide gap |
| 3 IV rank | Where IV sits over a year | Roughly 30–60 | Under 20 or over 80 |
| 4 Quality | Profit, debt, cash flow | All yes | Any no |
| 5 Earnings | Date vs expiry | Outside the expiry | Inside it |
A worked example (an illustration, not a trade idea)
You have $20,000 and a one-fifth cap, so $4,000 per name. A made-up stock, XYZ, trades at $38.
- Price: a $35 put sets aside $3,500. Passes.
- Liquidity: the $35 put shows open interest of 640 and a bid-ask of $0.70 / $0.76. Passes.
- IV rank: 44. Passes.
- Quality: profitable both years, debt is modest, cash flow positive. Passes.
- Earnings: in 52 days; your expiry is 38 days out. Passes.
You sell the 38-day $35 put for $0.72. You collect $72.
| XYZ at expiry | What happens | Shares | Premium | Total |
|---|---|---|---|---|
| $29 | Assigned at $35; worth $29 | −$600 | +$72 | −$528 |
| $33 | Assigned at $35; worth $33 | −$200 | +$72 | −$128 |
| $34.28 | Assigned; break-even | −$72 | +$72 | $0 |
| $35 | Put expires or assigned at cost | $0 | +$72 | +$72 |
| $42 | Put expires | — | +$72 | +$72 |
Passing every step didn't stop the first row. XYZ fell 24% on a bad sector day, no earnings needed, and you lost $528. The screen's job isn't to prevent losses. It's to make sure that when you're assigned, you own a business you'd keep, with options you can trade, and no shock you could have seen coming.
What to do next
- Set your per-name cash cap and your top share price.
- List ten stocks you know. Run steps 1 and 2 on each; many lists lose half here.
- Run steps 3 to 5 on what's left.
- Write the survivors in a watchlist with the date you checked them. See building a wheel watchlist.
- Re-run the screen monthly. Names come off as often as they go on.
Questions
What's the best free stock screener for the wheel?
Most brokers have one built in with price, market cap and dividend filters. Few screen by option liquidity or IV rank, so those two steps are usually done by opening the chain. We don't recommend any one tool.
How many stocks should pass the screen?
Five to ten is plenty for most accounts. More than that and you can't watch them. If thirty pass, your filters are too loose; tighten the quality step.
Should I screen for the highest premium?
No. Premium is the output of volatility, and the highest-paying names are the ones with the most risk priced in. Screen for affordability, liquidity, quality and timing, and accept whatever premium those names pay.
Do ETFs go through the same screen?
Steps 1, 2 and 3 apply. Step 4 becomes "would I hold this fund for years?" and step 5 mostly drops away, since funds have no earnings date. See best ETFs for the wheel strategy.
