Selling Cash-Secured Puts

What is a Cash-Secured Put?

A cash-secured put is when you sell a put option while holding enough cash in your account to buy the underlying shares if you get assigned. It's called "cash-secured" because your obligation is fully backed by cash.

How It Works

When you sell a put option, you're agreeing to buy 100 shares of a stock at the strike price if the buyer exercises their option. In exchange, you receive premium upfront.

Example:

• Stock XYZ is trading at $50
• You sell the $47.50 put for $1.20
• You collect $120 in premium (1 contract = 100 shares)
• You need $4,750 in cash to secure the position

Three Possible Outcomes

1. Stock Stays Above Strike (Most Common)

• Option expires worthless
• You keep the entire $120 premium
• Return: 2.5% on $4,750 in capital

2. Stock Falls Below Strike at Expiration

• You get assigned 100 shares at $47.50
• Your effective cost: $47.50 - $1.20 = $46.30
• You now own stock at a discount to where you sold the put

3. You Close Early

• Stock moves in your favor, option loses value
• Buy back for less than you sold it
• Keep the difference as profit

When to Sell Puts

The best conditions for selling puts:

Step-by-Step Process

1. Identify a stock you want to own at a lower price
2. Check implied volatility - higher IV means better premiums
3. Select a strike price below current support levels
4. Choose an expiration - typically 30-45 days out
5. Calculate your return - aim for 1-3% monthly
6. Place the trade and set any alerts

Risk Management

Cash-secured puts have defined risk, but that doesn't mean unlimited downside is acceptable:

• Never sell puts on stocks you wouldn't buy outright
• Position size appropriately - don't put all capital in one stock
• Have a plan for assignment - will you sell calls or hold?
• Consider rolling if the position moves against you

Calculating Returns

Common Mistakes to Avoid

1. Selling puts on stocks you don't want to own - this leads to panic when assigned
2. Ignoring implied volatility - low IV means poor premiums
3. Going too short-dated - higher gamma risk
4. Over-leveraging - using margin without understanding risk
5. No exit plan - know when you'll roll or take assignment
