Getting paid to wait for a price you'd be happy to buy at — and what it costs when you're wrong.
3 min read
A cash-secured put is the entry point to the wheel. You sell someone the right to make you buy 100 shares at a set price, and you're paid a premium up front for taking on that obligation. "Cash-secured" means you set aside the full purchase price, so if you do get the shares, you already have the money.
The trade only makes sense on a stock you would genuinely be happy to own at the strike, because owning it is the outcome you're agreeing to. If you'd resent holding it, you're not running the wheel — you're betting the stock doesn't fall, which is a different trade with worse odds than it looks.
$5,000 per contract.Selling one 30-day put
Stock trades at $52. You sell one $50 put expiring in 30 days for $1.20.
Collateral set aside: $5,000. Premium received: $120.
Return on capital: $120 / $5,000 = 2.4% over 30 days (~29% annualized).
Breakeven: $50 − $1.20 = $48.80.
Above $50 at expiration: the put expires worthless, you keep $120, capital is free again.
Below $50: you buy 100 shares at $50, but your effective cost is $48.80.
Strike selection is the whole trade. Further out of the money means a lower chance of assignment and less premium; closer to the money means more premium and a higher chance of owning shares. Neither is correct in isolation — it depends on whether you want the stock.
| Strike choice | Delta (rough) | What you're saying |
|---|---|---|
| Well below the price | 0.10–0.20 | I mostly want the premium, assignment would be a surprise |
| Moderately below | 0.20–0.35 | The common wheel range: decent premium, assignment is fine |
| At or near the money | 0.45–0.55 | I actively want these shares and I'm being paid to wait a little |
Delta is a useful shorthand here: a 0.30 delta put has roughly a 30% chance of finishing in the money. Rough, not exact — see the Greeks for what that number really measures.
Your downside is the stock's downside, minus a small cushion
Collecting $120 against $5,000 of collateral means the premium absorbs a 2.4% drop. A stock that falls 30% leaves you holding a loss of roughly $1,380 on that position. The premium feels like protection and is really just a discount — selling puts does not reduce how far a stock can fall, it only changes the price you paid to be exposed to it.
The second failure mode is subtler: the capital is committed. While $5,000 sits as collateral it isn't available for anything else, including a better opportunity that appears next week. A string of small premiums on a stock going quietly sideways-to-down can underperform simply owning something better.
Earnings
Premium is high before an earnings report because the market is pricing in a possible gap. Selling into that is a real strategy, but it's a different one — you're being paid more precisely because the risk is larger. Wheel Folio flags open positions whose expiration falls after an earnings date so it's never a surprise.
If the put expires worthless, sell another one. If it's assigned, you own 100 shares and the wheel turns to covered calls. If you want to avoid assignment without closing for a loss, look at rolling.

Educational only
Nothing here is investment, financial, or tax advice. Options carry risk, including losing more than the premium collected, and the examples use round numbers to show the mechanics rather than to suggest a trade. Read risk and position sizing before putting real money behind any of it.
Assignment
The part that makes people nervous, and why on the wheel it's usually just the plan working.
