Cash-Secured PutStrategy
Generate regular premium income by selling put options with sufficient cash coverage.
What is a Cash-Secured Put?
A Cash-Secured Put is an options strategy where you sell a put option while keeping enough cash in your account to purchase the underlying shares if the option is exercised. This strategy is particularly suitable for investors who want to buy a stock at a lower price or generate regular premium income.
How Does It Work?
Select Stock
Choose a stock you would like to own at a lower price.
Sell Put
Sell a put option with a strike price at which you would buy the stock.
Collect Premium
You immediately receive the option premium credited to your account.
Reserve Cash
Keep enough cash ready (Strike × 100) to potentially buy the shares.
Practical Example
You want to buy Apple shares, but not at the current price of $180. You sell a put with a $170 strike.
What Happens With a Cash-Secured Put at Expiration?
Stock stays above strike (e.g., $175)
Put expires worthless
You keep the $300 premium as profit
Stock falls below strike (e.g., $165)
Put is exercised
You buy 100 shares at $170, effective price: $167
Stock exactly at strike ($170)
Uncertain
Put may be exercised or expire
What Are the Advantages of a Cash-Secured Put?
- Regular premium income
- Buy stocks below market value
- Defined risk
- Works in sideways markets
- Easy to understand and implement
- Lower risk than direct stock purchase
What Are the Risks of a Cash-Secured Put?
- Capital is tied up (opportunity cost)
- Loss risk in sharp price decline
- Limited profit potential (premium only)
- Obligation to buy shares if exercised
- Consider margin requirements
What Are Best Practices for Cash-Secured Puts?
Choose stocks you want to own
Only sell puts on stocks you would hold long-term.
Select strike price carefully
Choose a strike at which you would be happy to buy the stock.
Consider expiration
30-45 days often offers the best premium-to-risk ratio.
Check implied volatility
Higher IV = higher premiums, but also higher risk.
Avoid earnings
Don't sell puts right before quarterly reports.
