Cash-Secured Puts

Get paid to wait for a stock to come to you. Sell a put, collect premium upfront, and either keep the cash when the option expires worthless — or buy the stock at your target price at a discount.

The Basics

What Is a Cash-Secured Put?

When you sell a put option, you're giving someone else the right to sell you 100 shares of a stock at your chosen strike price. "Cash-secured" means you keep enough cash in your account to buy those shares if the option gets exercised.

In exchange, the buyer pays you a premium upfront. If the stock stays above your strike by expiration, you keep the premium and move on. If it drops below, you buy the shares at the strike — which is a price you already said you were happy to pay.

💡

The core idea: You're being paid to place a limit buy order. Instead of just waiting for a stock to hit your price, you collect income while you wait — and if it never drops, you still profit.

Key Terms

Strike Price

The price at which you agree to buy 100 shares. Should be a price you're genuinely happy to own the stock at.

Cash-Secured

You hold the full cash to purchase the shares (strike × 100) in your account as collateral.

Premium

The cash you receive upfront. Yours to keep regardless of whether you end up buying the stock.

Assignment

If the stock closes below your strike at expiration, you're assigned — you buy 100 shares at the strike price.

Put-Call Parity

CSPs and covered calls have the same risk/reward profile — just expressed differently.

Walk-Through

A Real Example

You like SPY at $470 and wouldn't mind owning it at $465. You set aside $46,500 in cash as collateral.

You sell 1 put with a $465 strike expiring in 30 days. You collect $2.85/share = $285 premium credited to your account immediately.

Wait for expiration. Two outcomes:

✓ SPY stays above $465

Put expires worthless. You keep the $285 premium and your $46,500 cash. Sell another put next month.

+$285 income, ~7.4% annualized

⬇ SPY drops below $465

You buy 100 shares at $465. Your effective cost basis is $465 − $2.85 = $462.15/share. Now sell covered calls to generate more income.

Profit & Loss

The P&L Profile

Profit is capped at the premium. Risk is owning the stock at the strike price if it falls below.

Profit zone — stock stays above strike

Loss zone — stock falls below breakeven

Strike — assigned below here, buy at discount

Strategy

When to Use It

Cash-secured puts work best when:

You want to own a stock but think it's slightly overpriced right now
You have cash sitting idle and want to generate income on it
The stock has elevated implied volatility (more premium)
You're bullish or neutral on the underlying
You want to pair with covered calls in the "Wheel Strategy"

⚠️

Only sell puts on stocks you WANT to own. If the stock gets assigned and craters, you're holding a losing position. Never sell a put on a stock you wouldn't want in your portfolio.

Metrics

What to Target

0.25–0.35

Delta at entry

~25–35% probability of assignment. Good balance of premium vs. risk.

30–45

Days to expiration

Optimal theta decay zone. Close at 50% profit or 21 DTE.

1–2%

Premium / cash secured

Target 1–2% return on the cash held as collateral per month.

IV Rank >30

Implied volatility rank

Sell when IV is elevated — you collect more premium for the same risk.
