Cash-Secured Puts: The Complete 2026 Guide

A cash-secured put is the mirror image of a covered call — and the entry point to half of the wheel strategy. You sell a put option on a stock you'd be happy to own, set aside enough cash to buy 100 shares at the strike, and collect premium income. If the stock stays above the strike, you keep the premium. If it dips below, you buy quality shares at a discount. Either way, you get paid to wait.

How Selling Cash-Secured Puts Works

The mechanics in four steps:

1. Pick a stock you actually want to own.Cash-secured puts are not speculation — they're a buy-the-dip system with a built-in income stream.
2. Choose a strike price below today's priceat a level you'd gladly pay. For a stock at $50, you might sell the $47 put (6% below market).
3. Set aside the collateral.The put is "cash-secured" because you reserve enough cash to buy 100 shares at the strike — $4,700 in the example above.
4. Collect the premium and wait. If the stock stays above $47 at expiration, the put expires worthless and you keep the entire premium. If it dips below, you get assigned 100 shares at $47, with a true cost basis of $47 minus premium.

Cash-Secured Put Example with Real Numbers

Suppose AMD is trading at $155. You sell the 30-day $145 put for $2.10, collecting $210 in premium. You set aside $14,500 in cash as collateral. Three possible outcomes:

• AMD stays above $145: Put expires worthless. You keep the $210. Return on collateral: 1.45% in 30 days, or ~17.4% annualized — without ever owning the stock.
• AMD dips to $142:You're assigned 100 shares at $145. True cost basis: $145 − $2.10 = $142.90. You bought a dip in a quality name at an effective price 7.8% below where it started.
• AMD crashes to $120:You're still assigned at $145. Cost basis $142.90, current value $120 — an unrealized loss of $2,290. The premium softens it but doesn't eliminate it. This is why stock selection matters.

Cash-Secured Put vs Covered Call: What's the Difference?

Both are short-premium strategies that benefit from theta decay. The structural difference is what you collateralize with:

• Covered call = sell a call against 100 shares you already own. Collateral is the stock itself.
• Cash-secured put = sell a put against cash equal to 100 shares at the strike. Collateral is cash.

For tax and risk purposes, they have a similar profit/loss profile at expiration. The main practical difference: a covered call is the natural strategy when you already own shares, while a cash-secured put is the natural strategy when you want shares but at a better entry price.

Choosing the Right Strike Price

Strike selection drives every outcome. The same framework from our covered call strike guide applies in reverse:

• Delta 0.30 puts:~30% chance of assignment. Balanced premium with a real buffer. The most common "wheel" entry.
• Delta 0.15–0.20 puts:Lower premium, lower assignment risk. Best for stocks you'd rather collect income on than actually own.
• Delta 0.40–0.50 puts: Aggressive entry, near-the-money. High premium and high probability of assignment. Use only when you genuinely want to be assigned.

Risks of Selling Cash-Secured Puts

Cash-secured puts have the same downside profile as owning the stock outright below the strike. The premium softens the blow but doesn't eliminate it. Key risks:

• Gap-down risk. A bad earnings report or geopolitical shock can blow through your strike overnight. The premium might cover 1% of a 15% gap-down.
• Opportunity cost on collateral. $14,500 set aside on a single put earns nothing else (besides T-bill yield if your broker pays it). Sizing matters.
• Assignment timing. American-style equity puts can be exercised early, especially around ex-dividend dates and on deep ITM contracts.

Tracking Cash-Secured Puts Properly

Tracking puts is harder than tracking calls because of the cash collateral. Most spreadsheets either (a) ignore the collateral and inflate your return, or (b) double-count when assignment converts cash into shares. CoverEdge handles both sides of the wheel natively — every put trade is treated with the same lifecycle as a covered call, and when assignment converts cash into a stock position, the new cost basis is automatically calculated through the ledger.

FAQ

What's the difference between a cash-secured put and a naked put?

A cash-secured put has enough cash reserved to buy the shares if assigned. A naked put does not, relying on margin instead. Naked puts have far higher risk and are usually only permitted on a margin account with options approval level 3+.

How much capital do I need to sell cash-secured puts?

Strike price × 100. For a $20 stock, that's $2,000 per contract. Most traders start with $5,000–$10,000 to diversify across 2–3 underlyings.

Can I roll a cash-secured put?

Yes — and the same rolling principles apply. Rolling down and out (lower strike, later expiration) is the most common defensive move when a put goes in-the-money but you don't want to be assigned yet.

Are cash-secured puts a good strategy for beginners?

They can be — but only if you have the cash to back them and you treat assignment as a feature, not a bug. Many traders start with cash-secured puts as their first options strategy because the maximum loss is clearly defined (strike × 100 − premium) and identical to simply buying the stock outright below the strike.
