Short Put Strategy
Selling puts is one of the most popular premium-collection strategies. Collect income when you are bullish on a stock, with the obligation to buy shares if the stock drops below your strike.
What is Short Put Strategy?
Short Put Strategy is a bullish income strategy where you sell a put option, collecting premium upfront. You profit if the stock stays above the strike price. If the stock falls below the strike, you are obligated to buy 100 shares.
Short puts can be cash-secured (full cash collateral) or margin-based (using less capital). The strategy benefits from time decay and falling implied volatility, making it popular among premium sellers.
TL;DR - Quick Summary
Short Put = Sell 1 put option. Collect premium immediately. If the stock stays above the strike, you keep the premium. If it drops below, you must buy 100 shares at the strike. Max profit = premium. Max loss = strike price minus premium (stock to zero).
What is a Short Put?
A short put means selling a put option to collect premium. You are making a bet that the stock will stay above the strike price by expiration. If it does, you keep the entire premium as profit. If the stock falls below the strike, you are obligated to buy 100 shares at the strike price.
Example: AAPL at $185. Sell a $175 put for $3.00 ($300 premium). If AAPL stays above $175 over the next 45 days, you keep $300. If AAPL drops to $165, you buy 100 shares at $175 with an effective cost of $172 after the premium.
Who uses short puts? Premium sellers, value investors waiting for pullbacks, and income-focused traders. It is one of the most common strategies used by professional options traders because time decay works in your favor every day.
When to Use Short Puts
- Bullish or neutral outlook: You believe the stock will stay flat or go higher
- High IV rank: When IV rank is above 50, put premiums are elevated, giving better credits
- Support level selling: Sell puts at key technical support where you expect the stock to hold
- Willing to own shares: Worst case, you buy a stock you like at a discount
Margin vs Cash-Secured
Cash-secured: Hold the full strike price in cash ($17,500 for a $175 put). Level 1 options approval. Very conservative.
Margin/Naked: Typically 20% of the underlying as margin ($3,500 for a $175 put). Level 3+ options approval. Higher return on capital but more risk if the stock drops sharply.
Profit & Loss Scenarios
Setup: Sell 1 SPY $520 put for $5.00 ($500). SPY at $540. 45 DTE.
SPY stays above $520
Put expires worthless. Full $500 premium is profit. This is the most likely outcome with a roughly 70-75% probability of profit.
SPY drops to $510
Assigned 100 shares at $520. Effective cost: $515 ($520 - $5 premium). Unrealized loss: $500. But you own SPY at a $25 discount to where it was when you sold the put.
Breakeven
SPY at $515 ($520 strike - $5 premium). Above this price, you profit. Below it, you lose.
