Cash Secured Put

Get Paid to Buy Stocks

Overview

Think of a cash secured put as getting paid to place a limit buy order. You're saying "I'll buy this stock at $X price" and the market pays you for making that commitment. If the stock stays above your strike, you pocket the premium and move on. If it drops below, you buy shares at a discount (your strike minus the premium you collected). It's the perfect strategy for building positions in stocks you want to own anyway—you either get paid to wait, or you get the stock at a better price than today.

Based on example: Sell AAPL $145 put for $2.50, hold $14,500 cash

How It Works

  1. 1Set aside cash equal to 100x the strike price
  2. 2Sell 1 put option at your target purchase price
  3. 3Collect premium upfront
  4. 4If stock stays above strike, keep premium (no assignment)
  5. 5If stock drops below strike, buy 100 shares at strike price

Key Parameters

Delta Target
0.20 - 0.40 (3 levels)

Delta tells you the probability of assignment. We show three levels so you can choose based on your goals: • Conservative (0.20Δ): ~80% chance premium expires worthless, lower income • Balanced (0.30Δ): ~70% chance, sweet spot for most traders • Aggressive (0.40Δ): ~60% chance, higher premium but more likely to own shares

Ideal DTE
7-90 days (30-45 preferred)

Shorter expiration (7-14 days): Quick premium, less time for stock to move against you. Longer expiration (30-45 days): Maximum theta decay efficiency—your time works hardest here. We search the full 7-90 day range and show you the best opportunities.

Min AROC
8%+

CSPs typically yield slightly less than covered calls (put skew), but 8%+ annualized still beats most alternatives. Since your cash is tied up as collateral, we want returns that justify the opportunity cost.

Choosing Your Delta Level

We show three delta levels so you can match the strategy to your conviction. Lower delta = safer but less premium. Higher delta = more premium but higher chance of assignment.

Conservative (0.20Δ)

Strike is further out of the money. You collect less premium but have ~80% chance of keeping your cash. Best for: income seekers who want steady premiums without buying shares.

Balanced (0.30Δ)

The sweet spot. Strike is moderately OTM. You collect solid premium with ~70% chance of expiring worthless. Best for: most traders who want decent income with reasonable assignment risk.

Aggressive (0.40Δ)

Strike is closer to current price. You collect rich premium but only ~60% chance of keeping your cash. Best for: traders who actually want to own the shares at that price.

Selecting Stocks for Cash Secured Puts

When selling puts, you're committing to potentially own the stock—so choose wisely. The best candidates are quality stocks that have pulled back to support levels, giving you a chance to "get paid to wait" for your entry price. Review the company's fundamentals: revenue growth, profit margins, debt levels, and competitive position. Avoid stocks in free-fall or facing existential threats.

Key Considerations

1Only sell puts on stocks you would happily own at the strike price
2Look for stocks that have pulled back 10-20% from recent highs
3Check support levels on the chart - sell puts near strong support
4Avoid selling puts into earnings unless you want the volatility exposure
5Higher IV environments provide richer premiums - elevated VIX is your friend
6Review the dividend schedule - assignment before ex-div means you get the dividend
7Consider position sizing: never put more than 5-10% of portfolio in one CSP

Pro Tips for Cash Secured Puts

These are techniques we've found useful. Your mileage may vary depending on your goals and risk tolerance.

The Wheel Strategy

CSP is half of the famous "Wheel" strategy. Sell puts until you get assigned, then immediately sell covered calls on those shares. Get called away? Go back to selling puts. Rinse and repeat for consistent income on stocks you love.

Support Level Targeting

Sell puts at or below key support levels on the chart. If the stock drops to support, you're buying at a level where buyers historically step in. Technical analysis meets income generation.

The 50% Rule

If your put loses 50% of its value quickly (stock rallied), consider closing early and redeploying. You captured half the premium in less time—your capital can now work on the next trade.

Rolling Down and Out

If your put is threatened (stock dropping toward strike), you can "roll" it: buy back the current put and sell a new one at a lower strike and/or further expiration. This gives you more cushion and often collects additional credit.

Assignment is Not Failure

Getting assigned means you bought a stock you wanted at a price you chose, minus premium collected. That's a win! Start selling covered calls immediately and continue the income cycle.

Position Sizing Matters

Never commit more than 5-10% of your portfolio to a single CSP. If you get assigned, you want enough capital to manage the position or average down. Concentration kills portfolios.

Example Trade

Setup
Sell AAPL $145 put for $2.50, hold $14,500 cash
Max Profit
$250 (premium if stock stays above $145)
Max Loss
$14,250 (stock goes to $0, kept $250)
Breakeven
$142.50 (strike - premium)

Best For

  • +Building positions in stocks you genuinely want to own
  • +Neutral to bullish outlook (you're betting it won't crash)
  • +High IV environments—elevated VIX means richer premiums
  • +Stocks that have pulled back to support levels
  • +Generating income while waiting for your target entry price

Risks

  • -Stock could drop significantly below strike—you're buying into a falling knife
  • -Capital is tied up as collateral (opportunity cost)
  • -May miss buying opportunity if stock rallies past your strike
  • -Early assignment risk near ex-dividend dates
  • -In a market crash, you'll be assigned on everything simultaneously
